Hi folks, I found the following in the Amphetamine FAQ:
Put your speed into a flask, beaker or some other container you can heat on a stove (note: use a stove without a naked flame, as these volatile organic chemicals produce explosive vapours). Pour acetone into the container so that the speed is completely submerged in it with a centimetre or 2 of excess liquid and swish it around to dissolve any soluble impurities. Next gently heat the acetone until it boils, and then take it off the heat. Now slowly add (with an eyedropper or pipette) just enough alcohol for all the speed to dissolve - stirring gently until the speed dissolves. If you add too much alcohol you won't get as high a yield as possible so don't add too much. Anything that doesn't dissolve is adulterant and should be separated out by filtration: use 2 coffee filters in a funnel to filter the solution, then cover it so a little air can escape and leave to cool to room temperature. Once it has cooled down you should notice crystals starting to form. Put the container in the fridge, and then the freezer to encourage more crystals to form (i.e., increasing the yield). The slower the solution cools, the larger the dry crystals will be. Once the solution has been freezer cooled, filter the crystals out with some coffee filters, then wash the filtered out solid in the funnel with a few drops of alcohol and allow to dry. Voila, you have pure speed. Save the acetone, it can be reused.

I have two questions regarding this to those who have done it before or know the chemistry behind it...

1) Why would I heat the acetone after all the impurities are already dissolved in it?

2) I don't get how adding the alcohol to the acetone would do any good... All the impurities and the amphetamine will now be dissolved in the solution and cooling the solution will just result in both impurities and ethanol to recrystallize, right? Or is the idea to add so much excessive acetone that no recrystallization will happen at a temperature change, while the little alcohol (that would get heated by the acetone when it is added) used will in fact force the amp out of solution?

I would've gone about this a different way intuitively:
-Dissolve impurities in acetone
-Filter (amp now in the filter)
-Add just enough warm ethanol to this for the material to dissolve
-Cool and watch crystals form
-OR just keep the filter's contents after puring the acetone off, clean enough I guess

I'd be very grateful if someone could clear this up cause I'll be starting to study in 3 wks lol!
 
meth crystals are larger when allowed to form at room temperature,followed by a refigerator,with a faster drying and crystalization time,but smaller crystals.The freezer is the quickest way for the crystals to form but produces/grows,the smallest crystals of the three ways.Best at room temp. overnight somewhere dry and a little warm.If you are in a hurry then use the fridge or freezer,but they will be much smaller crystal.The size of a crystal of methamphetamine does not have anything to do with it's purity or yield when washing it in acetone.And never heat the acetone to boiling,vaporize the acetone off 20 seconfds or so at a time in a microwave oven,take it out,let it cool off and repeat,not letting the glassware or whatever get too hot..always allow a minute or so of cooling when vaporizing off acetone or alcohol in the microwave...

I appreciate your trying to help, but that really doesn't answer my question at all... :D Besides, it's amphetamine, not methamphetamine.
 
Concentrated sulfuric is a stringer oxidising/dehydrating agent than dilute sulfuric, so using 25-50% shouldn't be an issue. You'll probably want to recrystallise it anyway to remove any residual water.
