Toluene vapor has a sharp or sweet odor, which is a sign of exposure. 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. Will a reagent test even show it? The hydrogen bonds already have a huge effect, look at the BP of ethane, (−88.5 °C or 184.6 K). Cheers! 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. ... Reddit. 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 … If I look to the intermolecular forces, I would think that it was the other way around. 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. May cause central nervous system depression. But really, who the fuck cares? Gross. Here's a picture: So, I got out my heat gun and ~10 mL glass vial with a cap. 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. 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. Synonyms & Trade Names Methyl benzene, Methyl benzol, Phenyl methane, Toluol CAS No. 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 key to separating them seems to be the higher affinity that methamphetamine HCl has for water. Tartaric acid is derived from natural sources, typically from winemaking, and as such it only occurs in the levo form. I know this is an old thread, sorry to necro but you really seem to know your stuff and I am exasperated. Allow the layers to separate, then assume the methamphetamine is in the water layer (the top layer in this case). The hardware store employee told me my state banned the import and sale of Toluene, only allowing stores to sell of existing stocks. Calixarenes are very heat stable. 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. It was an enjoyable and different high. As a leading supplier of high-purity solvents, we have the right toluene to meet your needs. 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. I actually added isopropyl alcohol to the water layer (I used 100% concentration, but 90-91% should work well too.) Reddit. Hey whattup 9000 haven't seen you around here in awhile how u been? Toluene is a common solvent, especially in spray paint. Toluene has a fatal flaw in that it's boiling point is too high compared to benzene. 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. 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. Which seems to fit your description. On top of not getting high, it kills my throat now. DOT ID & Guide. 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. 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. What is the actual difference between these solvents mentioned? Cookies help us deliver our Services. 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. Post your questions about chemistry, whether they're school related or just out of general interest. ... Reddit. 58 / Monday, March 26, 2012 / Rules and Regulations Date of issue: 03/21/2014 Revision date: … It's quite subtle, but eventually it's pretty easy to notice, and with experience, will produce a gag reflex of sorts. 4th Jul, 2019. Toluene is a clear, colorless liquid which becomes a vapor when exposed to air at room temperature. (1) Toluene exposure may also occur in the workplace, especially in occupations such as printing or painting, where toluene … The present protocols available to separate toluene/pyridine mixtures are several energy‐intensive distillation methods, which are not environmentally friendly and cost‐effective. 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. However, there is no 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. Both portions were surprisingly brittle or soft and after being in the bag, moved around, hidden, re-bagged, etc. Bleach was inconclusive. You're doing the Dark Lord's work. (For methamphetamine, "stereoisomer" and "enantiomer" are interchangeable, but they can mean different things if referring to other molecules.) If I remember correctly, one will dissolve in a common alcohol solvent, and the other will not. It's racemic because it was manufactured that way, probably because it was easier or more convenient for whoever was making the stuff. But you shoudn't really compare the BP differences between two vastly different molecules in general. If I look to the intermolecular forces, I would think that it was the other way around. Toluene is typically used in a mixture with other solvents and chemicals such as paint pigments. New comments cannot be posted and votes cannot be cast. Will that work as the non polar solvent? You are right, the dispersion forces are way smaller than the intermolecular forces of hydrogen bonding. 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. 108-88-3 RTECS No. 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. Ethanol can make hydrogen bonds and has a large dipole moment (1.7D), whereas toluene only has a dipole moment of 0.36D. Long term and repeated workplace exposure to toluene affect the central nervous system. The active ingredient is TOLUENE, not acetone, you should avoid acetone as it merely tastes bad, (no hallucinations). There should be plenty of YouTube videos out there showing how to do it. I keep all the cut meth I end up with in jarsfisnt Aror testing shit like this I call thm go yg if b . 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. 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 deliberate inhalation of paint or glue may result in high levels of exposure to toluene, as well as to other chemicals, in solvent abusers. Then I added twice the volume of water, in toluene. Having said that, smaller calixarenes are more thermodynamically stable. Reddit; Wechat; Abstract. I hope you speak truth, for it has been the darkest of days here in the gacklands. 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. Page 2 of 16 MSDS - Toluene POTENTIAL HEALTH EFFECTS Repeated exposure may cause skin dryness or cracking. It'd be a cold day in hell if his shit was the real deal. Related Pages. How do you know meth hcl isn't soluble in isopropyl alcohol? Anyway, I capped it and heated it up with the heat gun until it was all pretty hot to the touch. Sometimes, achieve desired effect, other times, not. Let's say, hypothetically speaking of course, that something seemed both wrong/off about this substance yet other characteristics seemed exactly as they should. As far as solvents go, I also have methyl ethyl ketone and limonene. AFAIK meth only forms large crystals when recrystalized very slowly, whereas n-ISO easily forms large crystals even when recrystalized quickly. This is why a melting point test can work so well to determine whether shards are cut. 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. 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. 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. Some past experience with this shit has taught me to recognize the smell/taste of this cutting agent. From what I've read about n-ISO I believe you've fucking done it my friend! Some of the additional effects of toluene include the following: Eye and nose irritation It arrived, and sure enough, was super clear, and had a bunch of very flat facets on its surface. Toluene occurs naturally in crude oil and in the tolu tree.
