All in One Thread for Ethyl-Methyl PMK Glycidate conversion to PMK
- Thread starter Fring
- Start date
someone can explain to me the difference on the molecul when it's powder or vax ?
why is like that, and when i am asking directly to them.... they don't have a real answer.
as a chemist mind... i really to understand everything.
and ok, the pmk glycidate was banned / ok the pmk methyl glycidate is banned / right to be clear we have only the PMK ETHYL GLYCIDATE.
someone knows the difference on the conversion ? or if this new group bring something different to the yield at the end.
i am curious to get some tips and differents point of view.
and i have the feeling the kind of oil we have at the end it's bit crappy..
someone has some technique to have a best oil, very clear and pure or doesn't matter during process ?
thank you

maybe this can sound annoying or excessively stupid of me, or maybe its the loose definitions thrown around all the time. When you guys say "the one that is solid", does that mean CAS 13605-48-6 or the 28578-16-7 in alleged "powder" form, and is there such thing? What do the chinese mean by powder 28578-16-7? It is my noob preconception that if there is a substance, it has it's own cas, if there is some salt of it, it's a different CAS.
So at the end of the day I would finally like to know what would the best procedure for CAS 13605-48-6 be? If it is the procedure previously described and referred to the Sydney bust, how can one optimize the maximum total volume in the flood ( for 35g, the paper indicates 600ml flood, very unpractical and troublesome)? And how can the copper step from the procedurebe skipped (using hcl?)
thanks everyone

and by the way, because... it sound right now most of the mdp2p from this new pmk glycidate it make me a dark and not very clear oil...
some people have few tips ?
cause i would like to know, after the conversion what is the best to extract this ketone.
which kind of solvent can i use to clean my oil ?
few method to make it more clear and pure ? ( distillation ? freezer ? washing with saturated nahco3 ?

why you all guys want to have a non dark oil? whats the matter? this is different pre-precursor, so the result is different...dark red oil... the goal is to have a clean and non dirty oil, following the descibed method (base-acid) the vacuum distill... the result is DIFFERENT, not the same GLY as before guys... so not the same colour...
As i was reading all topics about the PMK-glycidate with CAS: 28578-16-7 to be clear it can come in powder and in oil substance which can get hard under 33*C. All methods above is about the oil/wax substance.
As far as i could get notes about the process i write it in clear language so people can understand this better (included me). I have some questions about those improvements and what to do if made so.
Improvement as read at the forum:
Question about the improvement:
Do we heat this up to 80*C or do we keep it with NaOH at 20*C. Do we add PMK-gly-eth at 20*C directly or we heat more up?
Step 2: adding acid:
If improvement was made in the step with NaOH and we are adding hydrochloric acid do we raise temperature to 80*C? or do we keep it at 20-21*C? if keep it at 20-21*C do we continue again 12 hours or do we add this step within the first 12 hours?
Step 3 separation:
Step 4 vacuum distill:

well...didnt tried the saponification at room temp. for 12 hours, but i will for sure, since the dark brown colour in this conversion appears after the 80c saponification..maybe it can solve it...about other benefits i dont know....
as for the acid adittion, thats other proccess, yes you should put at 80ª for sure

well...the mistake here its because some folks thinks they can buy the old CAS , but thats not correct, the only available form is the waxy one, there arr 2 presentations of this , but its just the way the producer are finishing it..one is more yellow wax , and other is more white powder, but as soon as those reach 30ªc they will melt...its the same molecule, trust me.
same products, same proccess...
the matter of improve colour...well..maybe it exists but IMO all the new MDMA will be darker thatn before, you'll see...the new MDP2P is the same stuff but with a darker colour, then the MDMA will darker... just a bit , my results were like old unwashed "coca-cola" looking... no matter how much times you wash it, it keeps that colour

I am not an expert here, please contact @G.Patton @William Dampier , they are expert in this forum and very helpful
and please make sure your PMK cas no. is correct before proceeding any steps, here is few helpful links you might need to refer:

read better bro, the correct conversion its already posted, and yes, i have beautiful crystals , very small scale, but that will not make difference.
Conversion by alkali or acid. If a dirty product, purify with bisulfite adduct (soon video). If all this does not work, then your glycidate is trash.
I buy from chinese in nowember and december 2021 few kilo of what they told me was CAS 13605-48-6. They didnt deliver any instruction. So what i understand from BenyBoy i should do as below:
The method was provided for the one that is solid at room temp (mine is white powder)
1:1:1 PMK powder CAS 13605-48-6 :etanol : dh20 - heat at 60c for 1 hr
2. Add HCL heat 3.5 hr. At 75c (how much of HCL?) - can somebody give advice?
I ask because there is chance that i have old stuff thay they deliver in late 2021. If its impossible and i have the 28578-16-7 than i will do as it was in this post.
Is there any chance to tell the diference between 13605-48-6 and 28578-16-7 when its in the form of white powder?
Thank You
