When i have the mdma freebase i mix it 1:2 white aceton and bring ph to 2/3 and put it in freezer for 24 hours.
But nothing come? Somebody can help me?
Your Ratios are all wrong, You need a ph range of 7 - 6.5, because your PH is 2-3 your powder will solute again. Your next problem is that you need to make sure your Acetone is anhydrous and you need a Freebase to Acetone ratio of 1:4.
I guess you overestimate MDMA FB solubility in DCM, petroleum ether, hexanne and similar solvents. In the reality it is about 3-4 ml of those solvents per 1 gr of base.
If I understand it correctly, T must be kept 8-10C while all the stirring process.
What is expected ice consumption for 20-30L jacketed reactor used with a pump, submerged to a ice bath? Or this is wrong concept, and better to target for flow electric cooler?
Your method is using methylamine gas right? But methylamine is use methylamine HCI mix with methanol right? Can use methylamine solution to replace methylamine HCI?
Do you understand that methylamine gas is used in order to make methylamine methanol (MeOH) solution? Not methylamine hydrochloride methanol solution. You can directly use methylamine free base methanol solution.
