how is  denatured alcohol used in meth?

I've never heard of it being used. Most likely to wash it after it's already made.

no, you cant.\n\nU cant even test the pH for alcohol even if it is slightly acidic compared to other organic compounds, because it's a weaker acid than water. Alcohol can dissolve in aqueous soln; they dont ionize but form network of hydrogen bonds with water molecules.\n\nIn aqueous solution, no matter how basic it is, (let's say 14, that's the best u can do) alcohol will not lose an hydrogen atom 'cause its conjugate base is a stronger base than hydroxide ions (strongest base in aqueous soln). pKa for water is 15, alcohol is 16-18.

rinse in just plain water and than take a gulp of gin or whiskey, the water  is for the leftover food , the alcohol is for disinfection/\nand now to be serious, don't be cheap buy a bottle.

The most obvious reason is because it evaporates so quickly.  The cooling that takes place during evaporation causes water from the atmosphere to condense on it's surface.  This would lead to "wet" crystals.\n\nAlso, upon filtering the purified organic crystals you would see "ice crystals" form on the filter paper as the diethyl ether evaporated.\n\nA practical reason is because it is not one of the better solvents for most organic materials that one would wish to purify by recrystallization.  Alcohols are better for polar materials and benzene, dichloromethane or a petroleum hydrocarbon are better for others.\n\nIn terms of student lab, the anesthetic effects of the ether must also be considered.

To answer this question I would need to what material you're using (wood, metal or what)  and what are the dissolving tablets (Alka-seltzer or hydrocloric acid). Sorry.

You could probably just dehydrate it with concentrated sulfuric acid and heat.\n\nAnother method would be to generate a alkyl halide with thionyl chloride (SOCl2) and then eliminate it in a E2 reaction with sodium ethoxide in ethanol (especially strong base to be sure you get elimination, and not SN1)

rubbing alcohol will desolve most adheisives

You betcha! The fumes created by processing meth is deadly. It can cause maybe problems, the most of common of which are respiratory.  \n\nGod people are stupid. How could they do that to their child!???!

It gets denatured. All enzymes have a working temperature range. Bolilng would definitely lead to denaturation.

To perform a solution-based separation, you need a solvent in which one or some of the solutes (in the mixture to be separated) is/are highly soluble, and in which the other components are highly insoluble.\n\nA simple example might be separating an ethanol/pentane mixture by using water.  Ethanol, being polar, will readily dissolve in water; but the nonpolar pentane will not.

lol. Wtf? Are you planning on making mass amounts of Meth or blowing something up?

Distill it.\n\nIn cooking, supposedly you can put a piece of raw potato (sometimes, the hint says a piece of lettuce) in food that's too salty and it takes the salt out.  But I don't know if that works.  I'd go with distillation.  \n\nDistillation is where you boil a liquid and then catch the vapor and condense it.  In the case of salt water, the vapor would be plain water with nothing dissolved in it (the salt gets left behind in whatever you use to boil the liquid in.)  Distillation is also used to make an alcoholic liquid more alcoholic.  I guess the alcohol gets vaporized and condensed.

You're not going to easily deploymerize it. You may have a chance of dissolving it though. Look up its solubility parameter and choose a solvent with the same value of solubility parameter.

put it in the freezer and leave it.  the water will freeze and the alcohol won't.  that's why good vodka is kept in the freezer...

The ratio is 1 part rubbing alcohol to 2 parts water.I usually use 1 cup and 2 cups. Put the mixer in a gallon size zip lock then, place the zip lock into another zip lock to prevent any leakage. You can reuse this ice pack over and over. OR - you can make several smaller ice packs if you don't want a gallon size one.

methanol (rubbing alcohol);\n\none carbon, attached to one oxygen, with hydrogen everywhere else\n\nethanol (drinking alcohol);\n\ntwo carbons attached, one oxygen, with hydrogen everywhere else\n\nethyl ketone (very bad variation on ethanol, which is naturally occuring)\n\ntwo carbons attached, an oxygen attached by double bond, and hydrogen (one less hydrogen) everywhere else
