The two steps outlined above, in the washing and re crystallization procedure you are utilizing the solubility of MDMA in various solvents and temperatures. MDMA has terrible solubility in Acetone. You wash the MDMA in acetone, anything soluble in acetone is now gone. Dry the MDMA and heat Isopropyl, MDMA is soluble only slightly in iso, so by heating it you increase its solubility. Then the general practice is to throw this mixture in an ice bath now the solubility crashes, along with MDMA as a solid, crystallizing. Scratch the beaker with a glass stir rod if it is slow to occur.
You generally pick these solvents based on what your products solubility as various temperatures. You want all the junk to stay soluble and MDMA to crystallize
This is incorrect and this is why anhydrous magnesium sulphate is added to a pure acetone mixture to remove any H20.
MDMA and Amphetamines are only soluble in h20 not anhydrous acetone or anhydrous isopropyl alcohol.
Both are strictly to be anhydrous otherwise you will loose product.
As I said I lost minimal product weighing it prior and post wash then the product I was left with a clear product rather than a looking like crystaline sand.
My loss of product was somewhere placing the MDMA at 85% pure because as you know 11% of MDMA is made up of HCL which would have likely purified the product to it's maximum potential of 89%.
Furthermore I have decided to get my equipment together to test this theory with a roll report unaffected by any other subtances then another roll report of the mdma, mda and amphetamine sulphate mixture.
To clarify on an ice bath that's partially correct.
If you prefer for your crystals to be smaller and more glass shard like drop it in an ice bath.
If you prefer larger clearer crystals you reduce temperature gradually so no contaminants and present within the recrystallization.
This is also why an ice bath is a bad idea because it causes moisture which can make it's way into your solution and a higher temperature on cooldown allows the heat to rise and push the h20 away from your recrystallization.
Another thing to note that this is an easy process and highly recommmend for recreational amphetamine users.
You will never go back to unwashed drugs again.
So smaller crystals cooled quickly=less purity and potential contaminants trapped inside.
Larger crystals= Lower risk of impurities trapped inside.
This information was given to me with someone very high up with a high degree in chemistry.
Hope this helps.
Edit just read the post and I read it incorrectly I thought you were saying mdma is soluble in acetone.
This is also why a boiling stone or if you didn't want to raise alarms by going into a chemical/science shop you could use a matchstick as a boiling stone to eliminate the risk of anhydrous isopropyl alcohol from superheating and destroying your product.
