Cas 718-08-1

La síntesis del 3-oxo-4-fenil butanoato de etilo es la siguiente: El malonato monopotásico de monoetilo (12,9 g, 2,3 equivalentes) se mezcló con tetrahidrofurano (200 ml) y la mezcla se enfrió a 5°C. Se añadieron trietilamina (8,2 g, 2,5 equivalentes) y cloruro de magnesio (8,62 g, 2,8 equivalentes) y la mezcla se agitó entre 5 y 20°C durante 3 horas. La mezcla de reacción se enfrió a 5°C. Se añadió gradualmente cloruro de fenacil (5 g, 32 mmol, 1 equivalente) y la mezcla se agitó de 5 a 20°C durante 63 horas. La mezcla se enfrió a 5°C y se añadió ácido clorhídrico 1 N (30 ml). El tetrahidrofurano se evaporó a presión reducida y la extracción se realizó con acetato de etilo (50 ml). La capa orgánica se lavó sucesivamente con ácido clorhídrico 1 N (30 ml), agua (10 ml), solución acuosa saturada de hidrogenocarbonato sódico (30 ml) y agua (10 ml). El disolvente se evaporó a presión reducida para obtener el 3-oxo-4-fenil butanoato de etilo como un aceite amarillo pálido (5,82 g, rendimiento: 86%).
Pero ¿alguien ha trabajado en esto
Y ¿hay alguna manera en fósforo o limón

He oído que Cas 718-08-1 también es Bmk y no Pmk.
Pero existe el Nuevo Pmk que tiene el mismo método de fusión que el antiguo 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.
