Cas 718-08-1

Syntesen av etyl 3-oxo-4-fenylbutanoat är som följer: Monoetylmonokaliummalonat (12,9 g, 2,3 ekvivalenter) blandades med tetrahydrofuran (200 ml) och blandningen kyldes till 5°C. Trietylamin (8,2 g, 2,5 ekvivalenter) och magnesiumklorid (8,62 g, 2,8 ekvivalenter) tillsattes och blandningen omrördes vid 5 till 20°C i 3 timmar. Reaktionsblandningen kyldes till 5°C. Fenacylklorid (5 g, 32 mmol, 1 ekvivalent) tillsattes gradvis och blandningen omrördes under 63 timmar vid 5 till 20°C. Blandningen kyldes till 5°C och 1 N saltsyra (30 ml) tillsattes. Tetrahydrofuran indunstades under reducerat tryck och extraktion utfördes med etylacetat (50 ml). Det organiska skiktet tvättades med 1 N saltsyra (30 ml), vatten (10 ml), mättad vattenlösning av natriumvätekarbonat (30 ml) och vatten (10 ml) i följd. Lösningsmedlet indunstades under reducerat tryck för att erhålla etyl-3-oxo-4-fenylbutanoat som en blekgul olja (5,82 g, utbyte: 86%).
Men har någon arbetat med detta
Och finns det något sätt på fosfor eller citron

Jag hörde att Cas 718-08-1 också är Bmk och inte Pmk.
Men det finns New Pmk som har samma smältmetod som den gamla 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.
