And you will get MDMA everytime.
750 ml MeOH
150mg HgCL2(eyeball it)
27.5 g Aluminium foil, properly nuggetized. You might have a little left at the end, but not 10 grams.
I like to add about 5 ml of water to that mix(my MeOH is anhydrous). Also, I like to add a bit of nitromethane to the mix prior to drpping in the ketone/MeNO2 mix. Maybe 2-5 ml.
Drip in your ketone/MeNo2/MeOH. Addition should take about 30-40 minutes after your aluminium just started to float(which signals to start the addition)
Have a long condenser, more then 200mm.
Leave to stir for 3 hours. Add your NaOh solution and extract with your non-polar.
You now have your freebase in np.
Now you need to clean it up. MM doesnt clean it up enough to me. A minimum is an A/B to get quite pure MDMA.
Distilling after would be best.
So wash your Np with 5% NaOH a couple of times to get rid of any water soluble impurities present.
Then Acid extraction. Use 10 % HCl, 100ml then 50 ml extractions. At that scale, all the MDMA salt goes into the first 100 ml, but do another extraction to be sure.
You now have you MDMA in water. Wash that solution with fresh and clean non-polar. This is to get rid of np soluble impurities.
Basify your water solution until MDMA is turned into freebase again. The pka for MDMA is 9.6 which means that bringing the pH to 12 is well enough.
Extract that basic water with a non-polar to extract the freebase again.
You've now completed an A/B.
Dry the np and gas. You will get white crystals.
You really have to clean up your freebase or else it will turn either yellow, brown, maybe even red.
This is hard to fuck up. You wont maybe get 20 grams yield the first time, but after a little practice, youll get there.
For a proper answer, you will need to provide more details as to what you've done, how it looked, etc. This is where keeping track of everything you do, especially when you start, is useful. Keep a lab book. The only problem is the extra proof it gives to the DA. Good luck and dont give up you're so close!
