Cas 718-08-1

Syntesen af ethyl 3-oxo-4-phenylbutanoat er som følger: Monoethylmonokaliummalonat (12,9 g, 2,3 ækvivalenter) blev blandet med tetrahydrofuran (200 ml), og blandingen blev afkølet til 5 °C. Triethylamin (8,2 g, 2,5 ækvivalenter) og magnesiumchlorid (8,62 g, 2,8 ækvivalenter) blev tilsat, og blandingen blev omrørt ved 5 til 20 °C i 3 timer. Reaktionsblandingen blev afkølet til 5 °C. Phenacylchlorid (5 g, 32 mmol, 1 ækvivalent) blev tilsat gradvist, og blandingen blev omrørt i 63 timer ved 5 til 20 °C. Blandingen blev afkølet til 5 °C, og 1 N saltsyre (30 ml) blev tilsat. Tetrahydrofuran blev inddampet under reduceret tryk, og ekstraktion blev udført med ethylacetat (50 ml). Det organiske lag blev vasket med 1 N saltsyre (30 ml), vand (10 ml), mættet vandig opløsning af natriumhydrogencarbonat (30 ml) og vand (10 ml) i rækkefølge. Opløsningsmidlet blev inddampet under reduceret tryk for at opnå ethyl-3-oxo-4-phenylbutanoat som en lysegul olie (5,82 g, udbytte: 86 %).
Men er der nogen, der har arbejdet med dette
Og er der nogen måde på fosfor eller citron

Jeg har hørt, at Cas 718-08-1 også er Bmk og ikke Pmk.
Men der er New Pmk, som har den samme smeltemetode som den gamle 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.
