Synthèse d'huile de PMK à partir de PMK (CAS 28578-16-7 Wax Form) à grande échelle

[Curiousonion]

Cette méthode concerne le pmk CAS 28578-16. Vous pouvez donc l'obtenir sous forme de poudre qui se transforme en huile une fois la réaction terminée.
Mais cela semble extrêmement facile, est-ce que quelqu'un a essayé ?

It is bullshit from powder pmk dont work

 

[G.Patton]

Ce billet est une bonne explication, qui a été postée par @btcboss2022 (merci). Je confirme qu'il s'agit d'une méthode éprouvée et opérationnelle.

 

[C14]

Hello the pmk powder gkyciate got one special smell?? Maybe i.got fake pmk

 

[ukises]

Hello Funciona.para el pmk ethyl powder???

 

[C14]

Your methode Dont work for pmk powder

 

[G.Patton]

Hello, the method in this topic work for PMK methyl glycidate as well

 

[C14]

Methyl , but really for pmk ethyl powder dont work,thanks

 

[Jordan Belfort]

You mean that dark pmk powder with only desolved with ethanol/alcohol @C14

 

[G.Patton]

Are you sure that you have PMK ethyl glycidate?

 

[C14]

Really now not sure, i am cheking my pmk powder dont have any smell , i mean odor, it is neutro

 

[G.Patton]

It's not a test, check its melting point and compare with a literature data.

 

[C14]

If is oil pmk, how i can know if is original or not?

 

[G.Patton]

I'm talking about its precursor PMK methyl glycidate. P2P can be checked by its boiling point, density.

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.

also in after dcm add step 12 any layer sepration heppen ?
@btcboss2022
and last qustion what is the purity of mdp2p

What do u mean? Try to read your question before to post and understand, Is it readable or has a sense?
>and last qustion what is the purity of mdp2p
@btcboss2022 will not answer cuz he's offline Aprill 22th 2024.
It isn't possible to answer this question.
The same as ask, will your soup be taste? Nobody know how are you prepare it, dude...

 

[realboss]

. Add 3.25kg of HCL 37% in small portions, once all added keep the mixture at 80 °C reflux during 1 h stirring.
hcl 37% water solution ?

 

[C14]

Hello for what use.the s bicarbonate, for clean or.for change ph?

 

[Jordan Belfort]

Both, and probably some NaCl will be formed if aquous HCL has been used, resulting in general better kinetics (if minor trace stays in the oil).

 

[G.Patton]

It's need to carry out alkaline hydrolysis of ester.
