level 2. I will try when I get out of the hospital. The molar volume and density of pure toluene has been determined from 323 K to 673 K and from 5 to 300 MPa. Either way I will gladly take racemic/not as potent meth over this ISO bullshit any day of the fucking week! It was an enjoyable and different high. I'm sorry to ask another, what are the implications to ordering n-iso online? New comments cannot be posted and votes cannot be cast. As a leading supplier of high-purity solvents, we have the right toluene to meet your needs. Why has toluene (111°C) a higher boiling point than ethanol (78°C)? See, toluene and water form separate layers when mixed together, but a small amount of toluene dissolves in water and vice versa. Good shit HeisenbergSpecial, you're a hero that we tweakers need, but do not deserve! New comments cannot be posted and votes cannot be cast. I hope you speak truth, for it has been the darkest of days here in the gacklands. Reddit. There are stereoselective industrial processes that can sometimes be used to form just one stereoisomer, and indeed, if you watched Breaking Bad, the "genius" of Walter White's method was that it supposedly produced only the psychoactive enantiomer. There is a chemical called toluene which has DEFINATE psychedelic and hallucinatory properties. So the thing to note here is that n-iso (or whatever) is insoluble in dry toluene, no matter the temperature, but soluble in hot wet toluene. However, there is no (For methamphetamine, "stereoisomer" and "enantiomer" are interchangeable, but they can mean different things if referring to other molecules.) that a good portion of each piece was broken off and into tiny pieces, mixed together. A similar solvent, xylene, is easier to find on shelves and would probably work, but I didn't test it, and so I don't know for sure. Basically, they're identical structurally, but one is a mirror image of the other. DOT ID & Guide. It makes me cough and gives a tightness in my chest. The toluene-rich bottom phase could be later redistilled, to improve its purity. 9000 says keep up the damn good work!!!!! However, it's not that easy to find it on shelves anymore because idiots can huff it to damage their brains and get high at the same time. Press J to jump to the feed. Press question mark to learn the rest of the keyboard shortcuts. Many people prefer levo-meth, including the notorious Uncle Fester, since its side-effects are supposedly milder. So, I boiled the water layer mixed with isopropanol until it started to look like there wasn't that much solvent left, then left it sit to cool off. This revealed an interesting phenomenon. Toluene, also known as methylbenzene, is a clear, colorless liquid with a distinctive sweet smell that is widely used in industrial settings as a solvent. Calixarenes are very heat stable. Here's a picture: So, I got out my heat gun and ~10 mL glass vial with a cap. (only tried once) Small amounts were given to friends in baggies and none of them complained. Tartaric acid is derived from natural sources, typically from winemaking, and as such it only occurs in the levo form. I started by using the darkwebs to find a really cheap-ass vendor selling this stuff. It's quite subtle, but eventually it's pretty easy to notice, and with experience, will produce a gag reflex of sorts. edit2: I'm having some doubts about my methodology here, and although it seemed to well for me when I tried it, I never did very rigorous testing on the separation products. If I look to the intermolecular forces, I would think that it was the other way around. 16 different constant volumes have been used and with stepwise increasing temperatures, pairs of temperature and pressure values have been taken along isochors. Wait, I guess I have a third general chemistry question. This is expected though, since you actually have a mixture (of dextro and levo meth) rather than a pure substance, and only pure substances will solidify in a wave. Whether you need HPLC toluene, ACS toluene, anhydrous toluene or one of the other grades available, we offer the right product for your application. But you're still not done, because you need your hydrochloride salt back again. The present protocols available to separate toluene/pyridine mixtures are several energy‐intensive distillation methods, which are not environmentally friendly and cost‐effective. Pyrolytic soot formation of dilute fuel systems in Argon between 1500 and 2500 K at 10, 20, and 30 atm total pressure was examined using multiple wavelength diagnostic capability. I hope you can help. No. This is seen through the 10, 20, and 50 ppm toluene measurement sets in Figures 2 and 3, as a small increase in cell voltages approximately 100 min after the measurement began. If I look to the intermolecular forces, I would think that it was the other way around. Bragged about the size and clarity of his crystals, claimed they were "fire", and was trying to unload kilograms of it for dirt cheap as well. Cookies help us deliver our Services. A reactive Molecular Dynamics (MD) study of toluene oxidation at high temperatures under externally applied electrostatic fields has been performed. (To think they never even asked me. Although flat, layered n-iso crystals didn't form from the water layer, that doesn't mean there weren't any there, among other things. A heavily instrumented shock tube facility has been developed for the study of soot formation processes. 1294 130. Toluene is typically used in a mixture with other solvents and chemicals such as paint pigments. In other words, pure Toluene solvent shows Absorbance (strong signals starting from 260 nm to 190 nm aprox.) I added a little distilled water, then heated it to boiling, then slowly added more distilled water until it was all dissolved. So you can filter out what doesn't dissolve, and crystallize what does, which separates them. Additionally, high concentrations of toluene, usually from use in a confined space or unventilated area, can cause loss of consciousness, respiratory depression, and death. By using our Services or clicking I agree, you agree to our use of cookies. Some of the additional effects of toluene include the following: Eye and nose irritation This is apparently a thing now that people are writing exams from home. Does this similarity also apply to the substance in question? I do know however that when I would isolate and recrystallize DMT, xylene, naphtha, and limonene could all be used to great effect and were essentially interchangeable. Xylene and toluene are not available where I live. Bin Zhu, Lu-Yao Zhang, Meng Li, Yan Yan, Xiao-Min Zhang, Yi-Min Zhu, High-performance of plasma-catalysis hybrid system for toluene removal in air using supported Au nanocatalysts, Chemical Engineering Journal, 10.1016/j.cej.2019.122599, (122599), (2019). Let's say, hypothetically speaking of course, that something seemed both wrong/off about this substance yet other characteristics seemed exactly as they should. Reddit; Wechat; Abstract. Toluene vapor has a sharp or sweet odor, which is a sign of exposure. It'd be a cold day in hell if his shit was the real deal. The fuel systems examined were toluene, toluene with hydrogen, toluene with acetylene, and toluene with … A highly regio‐ and stereoselective syn‐carbometalation of terminal secondary or tertiary propargylic alcohols with primary alkyl Grignard reagents in toluene or phenylmagnesium bromide in Et 2 O was developed, in which the alkyl or phenyl group from the Grignard reagents is introduced into the terminal position of the alcohols. But really, who the fuck cares? Extreme overexposure (for example, in an enclosed or confined space) can cause pulmonary edema, a potentially life-threatening condition in which the lungs fill with fluid. An autoclave is described which has a variable internal sample volume. 58 / Monday, March 26, 2012 / Rules and Regulations Date of issue: 03/21/2014 Revision date: … Cheers! ... Reddit. Toluene is a common solvent, especially in spray paint. Synonyms & Trade Names Methyl benzene, Methyl benzol, Phenyl methane, Toluol CAS No. Formula. Regards. The 3‐MnO 2 sample prepared by using three equivalents of stoichiometric H 2 O 2 displays the best catalytic activity for the total combustion of toluene (concentration is up to 1000 ppm) at 300 o C. The mechanism of the influence of different H 2 O 2 addition amount has also been discussed by catalytic performance and nature of materials. Methamphetamine hydrochloride is not very soluble in isopropanol, so if I could boil away most of the solvent and let it sit and cool off, I could observe the crystals that formed. If I remember correctly, one will dissolve in a common alcohol solvent, and the other will not. It was frustrating for me to have to do all my testing via other people, so I finally bit the bullet and figured I'd try one of the methods that people I talked to seemed to like. You guys all know that you can make chloroform by adding a very small amount of acetone to very cold bleach, right? Second; I have vm&p naphtha. 77, No. Will that work as the non polar solvent? Also please don't use this sub to cheat on your exams!! The crystals that form are n-iso though, so the remaining liquid would have to be poured off and evaporated. Abstract. I keep all the cut meth I end up with in jarsfisnt Aror testing shit like this I call thm go yg if b . You're doing the Dark Lord's work. That was 2018. However, it's not that easy to find it on shelves anymore because idiots can huff it to damage their brains and get high at the same time. A number of case reports describe neonatal effects that have been attributed to toluene abuse during pregnancy. I started to get a headache just looking at it. I'm no proper chemist like yourself, but I am curious if you think you may have lost some potency in the final product, which is why it seems to be racemic/not as good as it should be? All their physical properties are the same too. This actually makes isopropanol useful for crystallization, since the solubility changes a lot more with temperature than it does with solvents that it's more soluble in. Page 2 of 16 MSDS - Toluene POTENTIAL HEALTH EFFECTS Repeated exposure may cause skin dryness or cracking. All Answers (2) 1st Apr, 2015. Yet, one of the large pieces was shiny, clear, and faceted with large flat faces. There should be plenty of YouTube videos out there showing how to do it. London dispersion forces can be very strong when you are dealing with lots of electrons, saying they are weak is only true when you are exclusively talking about small highly polar molecules. The deliberate inhalation of paint or glue may result in high levels of exposure to toluene, as well as to other chemicals, in solvent abusers. Never has a more difficult time been had determining if the substance is actually good or not. I attempted this, a little brazenly with my entire 1g sample. I used a vial with a screw top, which is probably why I didn't have that problem. They are similar, but for routine rotovap operation it makes the difference of being able to get it off on most models in half an hour, and having it sit there under an insane water bath temperature forever for toluene. TL;DR: If you're sick of crystal clear meth that makes you sleepy and listless and gives you a headache, then read the whole damn thing. I actually added isopropyl alcohol to the water layer (I used 100% concentration, but 90-91% should work well too.) XS5250000. The site may not work properly if you don't, If you do not update your browser, we suggest you visit, Press J to jump to the feed. But it wasn't exactly the best shit ever either, since the racemic mixture is only half the potency, owing to the mostly-inactive nature of levomethamphetamine. It easily separated into two layers, although both layers were somewhat cloudy. Toluene is a clear, colorless liquid which becomes a vapor when exposed to air at room temperature. The hardware store employee told me my state banned the import and sale of Toluene, only allowing stores to sell of existing stocks. Toluene Safety Data Sheet according to Federal Register / Vol. I smoked a joint the other day after a couple of months of strictly dabs. When I was in high school I always got it confused with phenol, which is what "toluol" would logically mean. Ethanol can make hydrogen bonds and has a large dipole moment (1.7D), whereas toluene only has a dipole moment of 0.36D. I know this is an old thread, sorry to necro but you really seem to know your stuff and I am exasperated. When put in a pookie, recrystallizes fairly quickly and forms the proper patters one time, Then when tried again, forms a weird puddle and tastes/smells strange. When it's made by reducing pseudoephedrine, it only forms dextro-meth, but when it's made using a more industrial type of synthesis, it'll form both dextro-meth and levo-meth, and this mixture is referred to as "racemic". It's just that only one (dextro-meth) happens to be psychoactive. Long term and repeated workplace exposure to toluene affect the central nervous system. When I went to shake the hot mix in the stoppered test tube, the entire contents blew out like it was new year's eve. Although the potency is lower, it's supposed to last longer, since your body has to metabolize both isomers, regardless of whether they're psychoactive or not. A hierarchical petal-on-petal MnO2/vertical graphene (VG) foam catalyst for high-performance toluene decomposition with low pressure drop in postplasma catalysis is demonstrated in this work. While it was hot, I took an eyedropper (actually a pipette, which is sort of like a big plastic eyedropper) and pulled all the water layer out and put it in another vial. Deep eutectic solvents (DESs), which are emerging as efficient green solvents, were introduced as the toluene absorbent in this work. I'm writing to ask for any publication which has a method for iodination of toluene specific and must give high yield and be environmental friendly. How do I know in advance which one to use for different applications? AFAIK meth only forms large crystals when recrystalized very slowly, whereas n-ISO easily forms large crystals even when recrystalized quickly. 108-88-3 RTECS No. Ethanol can make hydrogen bonds and has a large dipole moment (1.7D), whereas toluene only has a dipole moment of 0.36D. Post your questions about chemistry, whether they're school related or just out of general interest. Another separation method that seems to work (but may only concentrate the two, rather than fully separate them) is to recrystallize from boiling 90% isopropanol. Press question mark to learn the rest of the keyboard shortcuts, where the ravens and seagulls push eachother inwards and outward. Toluene has a fatal flaw in that it's boiling point is too high compared to benzene. (That is, due to the lower solubility in isopropanol, crystals would form in it more easily. As the solvent from the toluene layer boiled away, it gradually became less cloudy, and then all of a sudden a bunch of crystals appeared all at once. I have to keep things on the DL because of a roommate. Toluene. ... like it's an alcohol. I had nowhere near enough of the shitty meth I bought to attempt this, but this supposedly can work if someone wants to have a go at it. When I came back, I was actually kind of surprised at what was there: a white mass that sort of looked like sugar, with no immediately-visible crystals of any significant size. This could be repeated several times if there's too much n-iso remaining. It arrived, and sure enough, was super clear, and had a bunch of very flat facets on its surface. It's possible to "resolve" (meaning to separate) the isomers by forming the free base, (ie, removing the "hydrochloride" part of "methamphetamine hydrochloride") and then forming a new salt from tartaric acid instead of hydrochloric acid. So that means forming the free base again, and forming the HCl salt with hydrochloric acid. Measurements of the isochoric heat capacity, the critical point (TC, ρC) and vapor–liquid coexistence curve (TS, ρS) of high-purity toluene near the critical point. Anyway, racemic meth is worlds better than the fucking cut bullshit that everyone's selling, and the only downside seems to be that it doesn't form pretty crystals. Since both the acid (tartaric acid) and the base (methamphetamine) are chiral (have mirror images that aren't identical to themselves) this makes the tartaric acid salts of methamphetamine have different properties depending on whether the tartaric acid is forming a salt from dextro or levo meth. Bleach was inconclusive. Will a reagent test even show it? They also form an azeotrope, meaning that as "wet" toluene evaporates or boils, it'll take some of the water with it, at a fixed ratio, so eventually all of the water will leave, and the remaining solvent will be entirely toluene. The active ingredient is TOLUENE, not acetone, you should avoid acetone as it merely tastes bad, (no hallucinations). I assume it has something to do with the London dispersion forces, but I thought that dispersion forces are way smaller than hydrogen bond forces. I can also acquire ether. I can't find any data on it, but I see no reason it wouldn't be given that it's very soluble in water and quite soluble in ethanol as well. Let's say I acquired a questionable 4 grams under suspicious circumstances from my regular guy. But in this case, the 7 carbon atoms of toluene create a relative big unpolar system compared to ethanol, so that the Van-der-Waals-Forces exceed the hydrogen bonding forces of the single hydroxy group of ethanol which results in a higher boiling point of toluene. Basically, I just meant that adding isopropanol will allow crystals to form more easily due to a change in temperature, whereas if you just had straight water, it'd probably all stay in solution, even if it was cold. NFPA Hazard ID: Health: 2 Flammability: 3 Reactivity: 0 Also, because they don't quite fit together with each other, they'll only form crystals when the two enantiomers/stereoisomers are segregated from each other. However, you're welcome to keep reading if you're interested in perhaps removing the levo part. Their synthesis involves cracking their linear precursors at >150 C. Also I do further reactions on them at high temperature (160-180C) with no noticable degradation. Look it up if you're interested.). Toluene is a common solvent, especially in spray paint. If swallowed, may be aspirated and cause lung damage. What is the actual difference between these solvents mentioned? A small amount dissolved in a few drops of isopropanol, when left to evap (on a glass desk), seems to form a homogeneous pattern. Toluene occurs naturally in crude oil and in the tolu tree. Most recent answer. These seem to be n-isopropylbenzylamine hydrochloride. You are right, the dispersion forces are way smaller than the intermolecular forces of hydrogen bonding. Why has toluene (111°C) a higher boiling point than ethanol (78°C)? The highest concentrations of toluene usually occur in indoor air from the use of common household products (paints, paint thinners, adhesives, synthetic fragrances and nail polish) and cigarette smoke. Whether that is true or not, I have no idea. How do you know meth hcl isn't soluble in isopropyl alcohol? Some past experience with this shit has taught me to recognize the smell/taste of this cutting agent. The joint got me high as hell. Please do not post entire problem sets or questions that you haven't attempted to answer yourself. May cause central nervous system depression. Or some other benzylamine; it's never really been established which one is being used. on the real, a place for humans who prefer to go fast (in whatever way they like) to come together, commune, communicate, share stories of our lives, ask questions, share knowledge (always in the interest of harm reduction), make friends, and revel in the wonders of life. Plus, this is an important topic that needs to be discussed. (Oh yeah, you should probably start with two vials...) Then I used the heat gun to evaporate the toluene layer. From what I've read about n-ISO I believe you've fucking done it my friend! when the blank was exactly the same cuvette. I have two questions if you please Mr. Heisenberg. Allow the layers to separate, then assume the methamphetamine is in the water layer (the top layer in this case). Fluid Phase Equilibria 2008 , 263 (1) , 71-84. Related Pages. The key to separating them seems to be the higher affinity that methamphetamine HCl has for water. First, is there another test that can be used to determine the presence of n-iso aside from melting point test and a reagent test? You can explain it briefly, (if you choose to answer). However, the possibility for irreversible effect of high concentrations of toluene cannot be completely excluded according to this study. Exposure to toluene at high levels can irritate the lungs, causing chest pain and shortness of breath. Ooh, sorry to hear that. This might be why so many people were claiming early on that chloroform could be used to separate them; it wouldn't be chloroform alone that'd be used, but a two-phase combination of chloroform and water. Still, none of the n-iso bullshit lethargy and headaches, so I think we can chalk that up as a win. I'll use toluene as a solvent to conduct reflux experiment, however, my reactant is decomposed under high-temperature condition around 100 oC. Toluene is a widely used industrial solvent, and humans may also have high exposures to toluene from the deliberate inhalation ("sniffing") of paint reducer, paint thinner, or paint for their narcotic effects. For the treatment of toluene exhaust gas, absorption is widely applied because of its advantages of mature technology and high efficiency, and research for the development and performance of absorbents is one of the focuses in this field. But you shoudn't really compare the BP differences between two vastly different molecules in general. Then I shook it up a bunch. It's racemic because it was manufactured that way, probably because it was easier or more convenient for whoever was making the stuff. Sometimes, achieve desired effect, other times, not. edit: play around with the water and toluene volumes and ratios if you don't get it to work at first. I refuse to distill toluene from spray paint. You need to do it in a glass jug/bottle so you can see it collect at the bottom, among other things. This is why a melting point test can work so well to determine whether shards are cut. Then I added twice the volume of water, in toluene. Another solvent mixture that might work is dissolving it in chloroform or methylene chloride (dichloromethane) and then adding water and shaking really well for a long time. It's pretty cheap, from like sigma or whatnot. It's temporary but annoying. Which seems to fit your description. Natural compounds removed from marijuana during distillation for e-liquids and concentrates, and added back in for taste and smell, may produce toxic chemicals in … Anyway, I capped it and heated it up with the heat gun until it was all pretty hot to the touch. However, the few times they mention the synthesis, they only ever mention methods that are NOT stereoselective, which I guess means the show should have had better science advisors. Looks like you're using new Reddit on an old browser. Reason being, it's really annoying to try and characterize crystals that form from boiling water away, and just evaporating the water at room temperature takes a long time. ... Reddit. The effect of the OH instead of a simple H already increased the BP by ~150-160 degrees. Hey whattup 9000 haven't seen you around here in awhile how u been? (1) Toluene exposure may also occur in the workplace, especially in occupations such as printing or painting, where toluene … The hydrogen bonds already have a huge effect, look at the BP of ethane, (−88.5 °C or 184.6 K). Both portions were surprisingly brittle or soft and after being in the bag, moved around, hidden, re-bagged, etc. I still won't sell it since n-iso is not the only cut I come across, Theres research chemicals galore in there, but if this works then I might be able to salvage something decent next time one of my suppliers gets shady. May be irritating to the eyes, nose, throat, and lungs. It is soluble in isopropanol, just not nearly as soluble as it is in water, ethanol, or methanol. For example, let's say it looked good; cloudy, waxy, heavy, dense, bitter; lines going in same direction. "Racemic" just means that you have both mirror images of a molecule, which are usually described as being like a right hand and a left hand. Toluene naturally occurs in crude oil at low levels and, as such, toluene is typically generated during the process of making fuels from crude oil. Gross. The production of high purity toluene and pyridine is of significance in both industrial production and synthetic chemistry. It has to do with pi stacking, and toluene’s molecular weight. Isopropanol also forms an azeotrope with water. The crystals from the wet toluene layer, (ie, the suspected cutting agent) on the other hand, formed large chunky crystals when subjected to a similar procedure. Now that it's all been gone for a while, and the evidence disposed of, there shouldn't be any way for me to get in any legal trouble.
