This is apparently a thing now that people are writing exams from home. Plus, this is an important topic that needs to be discussed. ... like it's an alcohol. Whether that is true or not, I have no idea. Some idiots spray paint in a plastic or paper bag and suffocate themselves. Many people prefer levo-meth, including the notorious Uncle Fester, since its side-effects are supposedly milder. It easily separated into two layers, although both layers were somewhat cloudy. Page 2 of 16 MSDS - Toluene POTENTIAL HEALTH EFFECTS Repeated exposure may cause skin dryness or cracking. The fuel systems examined were toluene, toluene with hydrogen, toluene with acetylene, and toluene with … I will try when I get out of the hospital. Either way I will gladly take racemic/not as potent meth over this ISO bullshit any day of the fucking week! 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? Regards. Abstract. Does this similarity also apply to the substance in question? Exposure to toluene at high levels can irritate the lungs, causing chest pain and shortness of breath. Some of the additional effects of toluene include the following: Eye and nose irritation Additionally, high concentrations of toluene, usually from use in a confined space or unventilated area, can cause loss of consciousness, respiratory depression, and death. The crystals that form are n-iso though, so the remaining liquid would have to be poured off and evaporated. Post your questions about chemistry, whether they're school related or just out of general interest. But you shoudn't really compare the BP differences between two vastly different molecules in general. Related Pages. 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. The present protocols available to separate toluene/pyridine mixtures are several energy‐intensive distillation methods, which are not environmentally friendly and cost‐effective. 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. 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. Synonyms & Trade Names Methyl benzene, Methyl benzol, Phenyl methane, Toluol CAS No. I started to get a headache just looking at it. Hey whattup 9000 haven't seen you around here in awhile how u been? 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. 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. I can also acquire ether. Formula. 108-88-3 RTECS No. On top of not getting high, it kills my throat now. Toluene is typically used in a mixture with other solvents and chemicals such as paint pigments. Long term and repeated workplace exposure to toluene affect the central nervous system. 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. 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. You guys all know that you can make chloroform by adding a very small amount of acetone to very cold bleach, right? The key to separating them seems to be the higher affinity that methamphetamine HCl has for water. It's temporary but annoying. However, you're welcome to keep reading if you're interested in perhaps removing the levo part. Press J to jump to the feed. So that means forming the free base again, and forming the HCl salt with hydrochloric acid. Deep eutectic solvents (DESs), which are emerging as efficient green solvents, were introduced as the toluene absorbent in this work. 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. 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. 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. Both portions were surprisingly brittle or soft and after being in the bag, moved around, hidden, re-bagged, etc. ... Reddit. 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. 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. It is soluble in isopropanol, just not nearly as soluble as it is in water, ethanol, or methanol. Let's say, hypothetically speaking of course, that something seemed both wrong/off about this substance yet other characteristics seemed exactly as they should. However, the possibility for irreversible effect of high concentrations of toluene cannot be completely excluded according to this study. 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. 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. 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. 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. 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. As far as solvents go, I also have methyl ethyl ketone and limonene. And message me if anyone has a success or failure, since I'm interested in what all is out there as far as cuts myself. The hydrogen bonds already have a huge effect, look at the BP of ethane, (−88.5 °C or 184.6 K). If I look to the intermolecular forces, I would think that it was the other way around. Xylene and toluene are not available where I live. Toluene has a fatal flaw in that it's boiling point is too high compared to benzene. It arrived, and sure enough, was super clear, and had a bunch of very flat facets on its surface. Will that work as the non polar solvent? 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. Toluene vapor has a sharp or sweet odor, which is a sign of exposure. Most recent answer. 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 … 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. New comments cannot be posted and votes cannot be cast. (Oh yeah, you should probably start with two vials...) Then I used the heat gun to evaporate the toluene layer. 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 naturally occurs in crude oil at low levels and, as such, toluene is typically generated during the process of making fuels from crude oil. The joint got me high as hell. I attempted this, a little brazenly with my entire 1g sample. It was an enjoyable and different high. The toluene-rich bottom phase could be later redistilled, to improve its purity. I smoked a joint the other day after a couple of months of strictly dabs. 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. Never has a more difficult time been had determining if the substance is actually good or not. 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. By using our Services or clicking I agree, you agree to our use of cookies. (To think they never even asked me. 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". 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. Toluene Safety Data Sheet according to Federal Register / Vol. Tartaric acid is derived from natural sources, typically from winemaking, and as such it only occurs in the levo form. 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. Then I added twice the volume of water, in toluene. So you can filter out what doesn't dissolve, and crystallize what does, which separates them. 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. 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 can explain it briefly, (if you choose to answer). However, there is no 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. Here's a picture: So, I got out my heat gun and ~10 mL glass vial with a cap. 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. May be irritating to the eyes, nose, throat, and lungs. Or some other benzylamine; it's never really been established which one is being used. 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. This could be repeated several times if there's too much n-iso remaining. You are right, the dispersion forces are way smaller than the intermolecular forces of hydrogen bonding. 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. May cause central nervous system depression. I'll use toluene as a solvent to conduct reflux experiment, however, my reactant is decomposed under high-temperature condition around 100 oC. 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. The hardware store employee told me my state banned the import and sale of Toluene, only allowing stores to sell of existing stocks. I refuse to distill toluene from spray paint. Cheers! Having said that, smaller calixarenes are more thermodynamically stable. Ethanol can make hydrogen bonds and has a large dipole moment (1.7D), whereas toluene only has a dipole moment of 0.36D. Why has toluene (111°C) a higher boiling point than ethanol (78°C)? (only tried once) Small amounts were given to friends in baggies and none of them complained. 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. Toluene. How do you know meth hcl isn't soluble in isopropyl alcohol? when the blank was exactly the same cuvette. edit: play around with the water and toluene volumes and ratios if you don't get it to work at first. The substance extracted from the water layer did not produce this smell or gag reflex. 16 different constant volumes have been used and with stepwise increasing temperatures, pairs of temperature and pressure values have been taken along isochors. Toluene occurs naturally in crude oil and in the tolu tree. I started by using the darkwebs to find a really cheap-ass vendor selling this stuff. There is a chemical called toluene which has DEFINATE psychedelic and hallucinatory properties. Toluene react with chlorosulphonic acid to produce o-toluene sulphonyl chloride at zero degree temperature but in that more than 20 % p-toluene sulphonyl chloride is form. Toluene is a common solvent, especially in spray paint. Press question mark to learn the rest of the keyboard shortcuts. Ooh, sorry to hear that. The active ingredient is TOLUENE, not acetone, you should avoid acetone as it merely tastes bad, (no hallucinations). Will a reagent test even show it? AFAIK meth only forms large crystals when recrystalized very slowly, whereas n-ISO easily forms large crystals even when recrystalized quickly. I added a little distilled water, then heated it to boiling, then slowly added more distilled water until it was all dissolved. XS5250000. Fluid Phase Equilibria 2008 , 263 (1) , 71-84. 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. ... Get high-quality answers from experts. Calixarenes are very heat stable. "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. 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. I have to keep things on the DL because of a roommate. Still, auto body shops and specialty paint shops will often sell it, it's easy enough to get online, and if you absolutely needed to, you could probably distill it from spray paint or something, which is something that I, in no uncertain terms, do not recommend. Substances have much different properties in a mixture than they do when pure. (1) Toluene exposure may also occur in the workplace, especially in occupations such as printing or painting, where toluene … 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.
