Syntéza oleje PMK z PMK (CAS 28578-16-7 vosková forma) ve velkém měřítku

[Curiousonion]

No tato metoda je pro pmk CAS 28578-16. Takže to můžete získat ve formě prášku, který se pak po dokončení reakce změní na olej.
Ale zdá se to nesmírně snadné, zkoušel to někdo?

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
Pokud jste postupovali krok za krokem, měli byste mít 2 vrstvy, vysvětlete mi bod po bodu, co přesně děláte

 

[C14]

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?

Dobrý den, pane, mohu použít tuto metodu
1. Ke 100 g prášku PMK přidejte 100 ml ethanolu a poté přidejte 100 ml destilované vody a poté uzavřete a míchejte při pokojové teplotě po dobu 90 minut, dokud se nestane trochu práškovitým.
2. Kapalinu přefiltrujte (prášek odvažte) a přidejte kyselinu chlorovodíkovou v poměru 1:2.
3. Prášek nasypte do reakční konvice, přidejte kyselinu chlorovodíkovou, začněte míchat, zvyšte teplotu na 75 stupňů a míchejte 3 hodiny. Objeví se tmavá olejovitá látka.
4. Olej vyjměte a použijte jej pro další krok.

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
