As I understand, MDMA solubility in boiling IPA is around 1.4 ml of IPA per 1 gr of chloride. May be, you can specify what is MDMA solubility in IPA at RT and frozen IPA?

I did try ABE with liquid kept in the freezer. There was 50 gr of salt that shall give 42 gr of FB. Immediately as alkaline was added, the solution was put into the freezes for 4 hours. Then p.ether previously kept in the freezer too was added. As the result, separation done much easier with 40...

thinking about birthday gift for myself. the best option, I believe is a programmable hotplate. what is the best option considering price/functionality for such device in the EU? I don't think I will use it for some complicated synth. but show recrystallization - yeah!

Did try S newly separated from your racemic. Difficult to say, how pure is this S, but effect is distinguishable different. First of all, it has much less stimulating effect: all is about emotions. Also detected: much less bruxism (me personally didn't feel any bruxism at all), less sweating...

I really love this re-crystallization method for its simplicity, but not 100% satisfied with color. This is the best result I was able to get with this method at point 107C. It is not bad, but still not perfectly white transparent. This time I checked the weight of water I drained.. It was 2...

28.2 gr yeld after re-crystallization. PH=8.

Yes, you are right, NaCl works pretty well. I tried it a couple of times in proportions 15-20 gr : 100 ml and it makes my life much easier. But still thinking, may be proper temperature can improve the process much better.

S-iso was taken after 24 hours in the freezer. Final yeld is 29 gr of pinkish powder. PH = 5 It was dissolved in water 1 gr : 1 ml, and heated up to 108C for re-crystallization. Second photo at point 106C. Color is weird. Probably around-2-4% of impurities. Next time I will wash it with...

Come on, man: you can do it. If me with my arms growing from my ass can, then you can too. And yes! Nothing is more pleasing to my eyes than MDMA after ether washing.

@G.Patton general, does it worth to heat the water + FB solution + p.ether 40/60 up to 38-39C while ether washing is performed? probably it shall increase ether solubility and make emulsion dissolvation more easy?

Small correction on Step 2: Prepared L-tartaric - 24.85 gr. Used 22 gr.

First time MDMA isomers separation. Full report. Step 1. 40 gr of FB washed with p.ether obtained. The color slightly yellowish but good. Step 2. 20.65 gr of L-tartaric CAS 87-69-4 prepared in 40 ml of water. Molar proportions FB:tartaric 1:08. FB and tartaric colled in the freezer till 0C...

if there is excess of acid probably there is only one way resolve this issue: to do ABE again. simple washing in acetone will not help.

Looks very similar with Vevor. Is it this one?

I tried to rethink all I read here about isomers separation, and it looks you are totally right: the best way is to do it in water. Just one thing is bothering: if we use FB and tartaric in molar proportions 1:1 there will be an excess of unreacted tartaric in bottom layer together with...

Then, how much is such revolut account?

How many hours I have to finalize the payment after the deal has been confirmed?

Rotavap, Distillation kit, for example. All of them are built on 24/40. I know, there are different adapters on the market, but I haven't seen any for 24/40. Probably, it is Aliex realm.
