PMK Oil Synthesys From PMK (CAS 28578-16-7 Wax Form) Large Scale

[Bartholomeus]

Thank you again for clarification
I see people are the same everywhere, you offer them purity they want the impure junk, it's the same everywhere

how many pmk-glycidate beginning?

 

[Curiousonion]

Thanks man, I was really searching for that method but could only find the methylamine gas route. This one seems much easier and safer.

 

[Curiousonion]

That method is for methamphetamine synthesis which is sensitive to water.
Since you are making mdma base I don't think the reaction needs to be kept anhydrous so the addition of the dessicant is not necessary.
Any one has any opinions on this?

???I think you didn't read carefully the text, 5kg mate!;-)

 

[btcboss2022]

Hello,

Is totally necessary is not about meth or mdma is about amine production in a water free reaction. With water inside this mixture the amine won't be produced correctly but anyway always you can test it yourself ;-)
Thanks.

 

[btcboss2022]

Clean one before crystalize, after crystallization is even more clean ;-)

 

[btcboss2022]

Sorry is imine production not amine haahah

 

[luckyboy888]

sir
Could you please make an example of the steps after getting the oil what method to apply after getting the oil to get the ''cola'' mdma

 

[Selassi]

Totally different question about this conversion... Hope u have an answer



Swim is going to do this conversion but his ptfe stirring rods for mixing havent arrived yet.

Can he for once stir with a 316 steel stirrer for once maybe for 1.5 hr? I know the hcl eats away the 316 but doesnt matter if its trash afterwards.

Does the steel which is solved by the hcl during the conversion impact or influence the conversion itself?

Or maybe colorchanges to the oil?



Swim needs to do thr conversion and cant wait untill thr ptfe stirring rods arrive...



Maybe someone has an alternative option?

 

[G.Patton]

I think it has influence, but it is negligible.

 

[Selassi]

Thats what i think too, its only 1,5hrs and the hcl is very diluted with water and there is also caustic to neutralize a part.
Its not like with 5449 that needs 5 hrs with stronger solutions

But if someone has xp with this let me know, swim starts saturday conversion

 

[Selassi]

Swim already succeeded the testconversion on phosphoric acid with 500gr of 28578

 

[Bartholomeus]

If i see correctly yield is somewhere between 350-370ml from 500g starting material?
Starting material was powder or wax oil?

 

[Selassi]

White powder starting material was this test, i also have sample from yellow waxy lumpy powder.
Swim will do a small testconversion tomorrow also on phosphoric acid...

 

[Bartholomeus]

Thanks very much for answers
Can you tell me what was temperature and time when converting it with phosphoric acid?
What was your ratio of reagents, if you could write down your synthesis in few steps it would be very nice contribution to community

 

[Selassi]

1kg P
1kg water
150gr NaOH

Mix and melt at 85/90 for 1hr

450gr Phos and again 1,5hr at 85/90

After should be immediate separation from the layers

 

[Sjeik]

Stirring needed doing the conversion ? Phos 85% ?

 

[Katty Korner]

This seems way more dense than the starting post. 1 kilo of pmk glycidate, 1 kilo of water (which iirc is one liter) and 150 grams naoh seems much denser than other posts.

It'd be much nicer if it was that dense, instead of requiring gallons for a few kilos.

Anyone care to say if this can be done at this density, or concentration of reagents?

 

[Curiousonion]

After this do you neutralize it with a bicarb solution and extract with dcm or use it as such?

 

[Selassi]

Yes washing after is prefferable as the oil is going to contain less contaminants.
But ye i also know people who just yank the oil straight into the reactionvessel after conversion.

 

[Curiousonion]

Ah ok, so you just do a bicarb wash or also a dcm extraction?
I noticed after the bicarb wash it looks grainy and once you extract it with dcm and evaporate it you get a pure oil
