Hello,
I got very small amount of powder after crystallizing in acetone are mostly big crystal pieces and I filter them yes.

Hi, so the method described in the beginning of this thread does work? And does one vacuum distill the ketone to purify afterwards? Is this necessary?
Hi, yes, it is still here by reason that it works. Yes, it worth to distill before further synthesis.
I think someone asked this, but I didn't see a reply. Can the amount of water be reduced in the initial step, with all other ratios staying the same? And can one use diethyl ether in place of dcm for all uses of dcm here?

Hello,
If you reduce the water amount possibly the oil will be less clean about replace DCM by Ether no problem.

Thank you! I doubt I'd ever go at this scale, but I'd probably just clean it up with the bisulfite addiction, I believe that works with ketones.
Hello,does put 47 mean is adding aluminum?What is the serving size?
For many years we have been engaged in the production of phenylethylamines.
MDMA - high purity and no impurities.
We get the substituted ketone from methyl glycidate.
We use several technologies in the production of MDMA.
The resulting ketone after the hydrolysis of glycidate, we fractionally distill under vacuum.
The purified ketone is mixed with methylamine and dried from the formed water. The resulting imine is reduced to amine.
We select the base and distill fractionally under vacuum.
All substances that are chasing to the desired temperature are discarded. The desired fraction is collected and neutralized in ether with trimethylchlorosilane.
The resulting salt is filtered on centrifuges and washed with chemical grade acetone.
After that, it is filtered again, dried and crystallization is formed on the basis of mixtures of alcohols.
The recovered crystals are washed again with ether to dry quickly.
A cycle of 4 days allows you to get from 50 kg of finished MDMA.
We are always ready to cooperate with manufacturers and wholesale buyers.
We can guarantee the quality of our products and services.

As we can see, 1 cycle I have 31 liters of MD ketone with a total weight of ~ 37.5 kg
The next photo is a filtered MDMA salt.
The next photo is the vacuum drying of an MDMA crystal.
And the crystal after drying.
As a result, we get a snow-white crystal of MDMA hydrochloride with a yield of 40-43KG, which by moles is more than 85-90%+ yield for ketone.

hello again , just to be sure, i need a more extense explanation in couple points, i was using with success the Fring metod, the one you mention here with a link, and yours there are a thing i need to be sure before to try/loss something, so:
in the finalm step, he just wash with NAOH and the remaining oil is vacuum distilled to get rid of the water in it , but you instead, add DCM, so the question is, i assume thats an extraction in the DCM , then you distill to get pure oil, right? i mean the oil goes to the DCM, a normal extraction?
so the step is , instead to wash with naoh, and discard the water layer, then distill to get rid of water, after you wash with bicarbonate, YOU DONT SEPARATE ANY LAYER? YOU JUST ADD DCM, THEN KEEP THIS DCM LAYER TO DISTILL AFTER? i think i understood, and sounds logicall, but i prefeer to read it from you , please let me know....
YIELD IMPROVEMENT
Possibly many people think about it or even do it, in fact I don't know why I don't put it in the process here because I do it each time hahahah
Point 8. "Discard the water top layer" MISTAKE always is remaining oil in the water layer so to improve oil yield we must extract that oil from this layer.
Method:
- Add NaOH+H2O solution to the water layer until PH 12.
- Add DCM to the mixture stir and let separate layers.
- Discard top layer.
- Add the bottom layer to the bottom layer separated in point 12.
- Optional before point 13 you can dry and filter the mixture.
Sorry to forgot to add it before!
Hi everyone, sorry but is the starting material here, this PMK wax. Is this just Paraffin Wax, Piperonyl Methyl Ketone PMK? Or is this PMK wax something completely different? Thanks
