Ei bine, această metodă este pentru pmk CAS 28578-16. Deci, puteți obține asta sub formă de pulbere, apoi se transformă în ulei după ce ați terminat cu reacția.
Dar acest lucru pare extrem de ușor, a încercat cineva acest lucru?

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

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

Bună ziua, domnule, pot folosi această metodă
1. Adăugați 100 ml de etanol la 100 g de pulbere PMK și apoi adăugați 100 ml de apă distilată și apoi sigilați și amestecați la temperatura camerei timp de 90 de minute până când devine un pic pulverulent.
2. Filtrați lichidul (cântăriți pulberea) și adăugați acid clorhidric într-un raport de 1:2
3. Turnați pulberea în cazanul de reacție, adăugați acid clorhidric, începeți să amestecați, ridicați temperatura la 75 de grade și amestecați timp de 3 ore. Veți vedea o substanță uleioasă de culoare închisă.
4. Scoateți uleiul și folosiți-l pentru pasul următor.

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).
