The difference between attack by methanol and attack by water is that aluminum methoxide is soluble in methanol, whereas aluminum oxide is insoluble in water: hence the corrosion rapidly stops with water, but continues with methanol. The Caution! Methanol, acetone, and toluene are flammable! No flames! Obtain 8 clean, dry 10x75 mm test tubes. If compound A is soluble in water and ethanol at room temperature and is insoluble in dichloromethane, petroleum ether, and toluene at all temperatures describe how you would recrystallize an impure sample of A if you only had these five solvents available to you.

These impurities are  15 Apr 1996 Methamphetamine (also known as speed, meth, crystal, crank, and Evaporate off the water and you have methamphetamine hydrochloride. The mixture is filtered while hot, and the precipitate of sodium zincate is washed on the filter with a little warm methanol. Sometimes when the meth is synthesized (especially by inexperienced cooks) it is not “washed” or recrystallized to filter out impurities. The methamphetamine HCl will disassociate from the non-polar solvent and dissolve in the aqueous HCl; this water/acid mixture is insoluble in the non-polar solvent, will separate from it in a layer that may drained from the separatory funnel, thus collecting the methamphetamine HCl in an aqueous solution. i;ve read that this is the best way to salt meth, but nowhere can i find which also, some cuts like msm might form as separate crystals, but then dilute meteorological. PURIFICATION: The product dissolves readily in methanol but not in water, so you can blend the two together to make a suitable solvent (mixed solvent recrystallization). An ideal mixing (total volume inlet = total volume outlet) of two incompressible fluids which is between water and methanol (SG =0. In comparison, the solubility ofsodium oleate also depends on temperature (2 g per 100 mL at 20 °C, vs. You cannot dry it out either once it's been mixed with alcohol, (water and IPA form an azeotrope). Methamphetamine use and manufacture can adversely affect people and animals for many years to come who have the misfortune of being in a place where it was made or used.

Recrystallization of salicylic acid contaminated aspirin Dissolve the impure aspirin in 15 ml of ethyl alcohol, in a 150 ml beaker, then warm on a hot plate and pour into the solution 25 ml of warm water. The production of methamphetamine has been made more difficult by federal regulations, like the Combat Methamphetamine Act of 2005, aimed at controlling the flow of precursor chemicals such as ephedrine and pseudoephedrine (found in some cold remedies), as well as other necessary components. For each of the above which of the following solvents would allow recrystallization: water, methanol, ethanol, toluene, ligroin.
