Uus pmk
Cas 718-08-1

Etüül-3-okso-4-fenüülbutanaadi süntees on järgmine: Monoetüülmonokaaliummalonaat (12,9 g, 2,3 ekvivalenti) segati tetrahüdrofuraaniga (200 ml) ja segu jahutati 5 °C-ni. Lisati trietüülamiini (8,2 g, 2,5 ekvivalenti) ja magneesiumkloriidi (8,62 g, 2,8 ekvivalenti) ning segu segati 5-20 °C juures 3 tundi. Reaktsioonisegu jahutati 5 °C-ni. Järk-järgult lisati fenüülkloriidi (5 g, 32 mmol, 1 ekvivalent) ja segu segati 63 tundi temperatuuril 5-20 °C. Segu jahutati 5°C-ni ja lisati 1 N soolhapet (30 ml). Tetrahüdrofuraan aurustati vähendatud rõhu all ja ekstraheeriti etüülatsetaadiga (50 ml). Orgaaniline kiht pesti järjestikku 1 N soolhappe (30 ml), vee (10 ml), küllastunud naatriumvesinikkarbonaadi vesilahuse (30 ml) ja veega (10 ml). Lahusti aurustati vähendatud rõhu all, et saada etüül-3-okso-4-fenüülbutanaat kahvatukollase õlina (5,82 g, saagis: 86%).
Kuid kas keegi on töötanud selle
Ja kas on võimalik fosfori või sidruni peal kuidagi

Ma kuulsin, et Cas 718-08-1 on ka Bmk ja mitte Pmk.
Kuid on olemas New Pmk, millel on sama sulatamismeetod kui vanal Pmk 28578-16-7

Just keep Adding hydrochloride acid to your Bmk untill you reach ph less than 1.
When you reach under ph 1
Keep stirring at room temperature for 17-18 hours
You will than see that the water is at the bottom and the oil on top.

Do NOT throw away the remaining water. Because if the yield is not high. Than the oil is still in the water.

So adjust the ph level with sodium hydroxide to neutralize ph to ph 7.

You will than see the oil coming out.
