Sorry, meant to say the white powder form.
So there are 3 forms, wax, oil and powder?

IF
I thought the original process was from powder form. So it was originally from the oil pmk version that you started not the wax powder? (I tried from the wax powder and once cooled down to room temperature the material does not seperate into 2 layers)
Curiousonion If you followed the process step by step you should have 2 layers, explain me point by point what you do exactly

Added h20 with distilled water, while it was warming up melted the powder then added it.
Refluxed for an hour, then added hcl and refluxed for another hour.
Stopped reaction, waited for it to cool and seperate.
No separation occurred.

CuriousonionH20 with distilled water?;-)
I Guess is a writing mistake you woukd mean NaOH.
What PH has your mixture now?Seems not enough HCL.

Yeah sorry, Naoh.
I added the exact amount of hcl as written in the procedure.
Once you add the hcl is start boiling and fuming and when you reach the hcl saturation levels the reaction just settles and changes color to yellowish.

CuriousonionWhat is the current PH?

that I don't know anymore, I did that workup last night and neutralized the acid.
What is the ph supposed to be?
I mixed the reaction with a bicarb solution then seperated it with dcm. That seems to work, dcm with oil goes to the top for some reason.

I will try another reaction now, what is the ph of the final solution after it cools down to 25c supposed to be?

CuriousonionIs not only about neutralize the acid is about to turns the mixture acid.PH after HCL process must be at least in 2. DCM goes to top?Something is wrong for sure now web must Discover what is.
I did that synth yesterday again and allí smooth like always.

Ok so I will try it again.
But I followed the exact procedure you wrote.
The dcm with oil in it has that smell that mdma usually has.
I also find it strange that the dcm goes to the top

btcboss2022UPDATE:
Tried it again at same ratios provided in original recipe for 333 grams pmk powder.
All ingredients were scaled down.
Upon adding the HCL to the reflux, waited another half an hour, measures ph, it was slightly above 2.
Added more hcl until ph was at 2.
Ended reflux, clear separation occurred.

One question, when the 2 layers seperate the oil looks very nice and clean.
Is the bicarb wash that really necessary? Can't the oil be used as such and impurities washed away when doing crystallization at the end?

Final "Cola" MDMA ;-)
btcboss2022
How did you get such big rocks of crystal? buchner funnel with vaccuum so the crystals get pressed?
And what was your yield from 1L of mdp2p oil to mdma hcl, how many dried Cola mdma crystals you got from 1l mdp2p?
If you maybe know the dry yield already :)

CuriousonionIn my opinion is necessary because is not only about impurities the final mixture is too acid so is not good idea to use it directly, the bicarbonate-water washing will remove part of that acid and any future process will be smoother.

ChingShihThe crystals are made with normal crystallization process first with acetone and later with water you can find a lot of different techniques for that.
From 1L I got around 900gr.

Hello,

After check and test the methods posted in the thread http://bbzzzsvqcrqtki6umym6itiixfhn...-methyl-pmk-glycidate-conversion-to-pmk.2013/ I decided the post the best method for me:

1. Put 47,5 liters of H2O in the reactor and add 2,5kg of sodium bicarbonate, stirring until complete dissolution, take out the mixture and keep it.
2. Put in the reactor 7L of H2O
3. Add while stirring 1,2kg of sodium hydroxide
4. While the H2O and the sodium hydroxide are mixing and getting temp put 5kG of wax PMK to melt by low heat.
5. When PMK is melted add it to the reactor and put the mixture at 80C reflux during 1 hour stirring.
6. Add 3,25kg of HCL 37% in small portions, once all added keep the mixture at 80C reflux during 1 hour stirring.
7. Stop stirring and put the mixture at 25C
8. Discard the water top layer.
9. Put again in the reactor the oil top layer.
10. Add the H2O and sodium bicarbonate mixture, stirring 2-3 minutes.
11. Add 10 liters of DCM( from freezer preferably)
12. Let it get separated around 10-15 min.
13. Evaporate DCM from the bottom layer.

Yield: 3,72kg of PMK oil
btcboss2022UPDATE:

In big scale step 6 must be done in cold, is very dangerous and slow to make that step in hot.

I thought refluxing it with HCl was enough. I know it would work with methyl glycidate, but what about ethyl? Is this krapcho decarboxylation?
