PMK eļļas sintēze no PMK (CAS 28578-16-7 vaska forma) lielā mērogā

[Curiousonion]

Šī metode ir paredzēta pmk CAS 28578-16. Tātad to var iegūt pulvera veidā, tad pēc reakcijas pabeigšanas tas pārvēršas eļļā.
Bet tas šķiet ļoti vienkārši, vai kāds to ir izmēģinājis?

It is bullshit from powder pmk dont work

 

[G.Patton]

This post is a good explanation, which was posted @btcboss2022 (thank you). I confirm, that it is a proven and working method.

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.

 

[C14]

Hello meting point is 66 degrees c ?. Dificul find this information, thanks

 

[btcboss2022]

IF
Ja jūs ievērojāt procesu soli pa solim, jums vajadzētu būt 2 slāņiem, paskaidrojiet man punktu pa punktam, ko tieši jūs darāt

Hello i got pmk.glicidate i dont know exactly cas number, but is white not shinning , it is fatty , In water in ph 10, i cooked 2 times with naoh and hcl but after i use hcl start precipitatie white powder again, i think that is not.necesary use naoh becouse the ph is alcal ine, you got any idea?

Sveiki, kungs, vai es varu izmantot šo metodi
1. Pievienojiet 100 ml etanola 100 g PMK pulvera un pēc tam pievienojiet 100 ml destilēta ūdens, tad aiztaisiet un maisiet istabas temperatūrā 90 minūtes, līdz tas kļūst nedaudz pulverveida.
2. Šķidrumu filtrē (pulveri nosver) un pievieno sālsskābi ar attiecību 1:2.
3. Ielej pulveri reakcijas katlā, pievieno sālsskābi, sāk maisīt, paaugstina temperatūru līdz 75 grādiem un maisīt 3 stundas. Būs redzama tumša eļļaina viela.
4. Izņemiet eļļu un izmantojiet to nākamajā solī.

Hello for 100 grms pmk, how many grams of hcl? Thanks

 

[C14]

Hello Hcl radio 1:2 you mean 100 gr pmk and 200 gram hcl?

 

[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.

 

[C14]

Hello , this one Add 3.25kg of HCL 37% pure. Not with something water? Thanks
