Cas 718-08-1

Etilo 3-okso-4-fenilbutanoato sintezė yra tokia: Monoetilmonokalio malonatas (12,9 g, 2,3 ekvivalento) sumaišytas su tetrahidrofuranu (200 ml) ir mišinys atšaldytas iki 5 °C temperatūros. Įpilta trietilamino (8,2 g, 2,5 ekvivalento) ir magnio chlorido (8,62 g, 2,8 ekvivalento) ir mišinys maišytas nuo 5 iki 20 °C temperatūroje 3 valandas. Reakcijos mišinys buvo atvėsintas iki 5 °C temperatūros. Palaipsniui buvo pridėta fenacilo chlorido (5 g, 32 mmol, 1 ekvivalentas) ir mišinys maišytas 63 valandas 5-20 °C temperatūroje. Mišinys buvo atšaldytas iki 5 °C ir įpilta 1 N druskos rūgšties (30 ml). Tetrahidrofuranas buvo išgarintas sumažintu slėgiu ir ekstrahuotas etilacetatu (50 ml). Organinis sluoksnis iš eilės buvo plaunamas 1 N druskos rūgštimi (30 ml), vandeniu (10 ml), sočiu vandeniniu natrio vandenilio karbonato tirpalu (30 ml) ir vandeniu (10 ml). Tirpiklis buvo išgarintas esant sumažintam slėgiui, kad būtų gautas etilo 3-okso-4-fenilbutanoatas kaip šviesiai geltonas aliejus (5,82 g, išeiga: 86 %).
Bet ar kas nors dirbo su šiuo
Ir ar yra koks nors būdas dėl fosforo arba citrinos

Girdėjau, kad Cas 718-08-1 taip pat yra Bmk, o ne Pmk.
Tačiau yra Naujasis Pmk, kurio lydymosi metodas toks pat kaip senojo 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.
