Cas 718-08-1

Etil 3-okso-4-fenil-4-butanoāta sintēze ir šāda: Monoetilmonokālija malonātu (12,9 g, 2,3 ekvivalenti) sajauca ar tetrahidrofurānu (200 ml) un maisījumu atdzesēja līdz 5°C. Pievienoja trietilamīnu (8,2 g, 2,5 ekvivalenti) un magnija hlorīdu (8,62 g, 2,8 ekvivalenti) un maisījumu maisīja 3 stundas 5-20 °C temperatūrā. Reakcijas maisījumu atdzesēja līdz 5°C. Pakāpeniski pievienoja fenacilhlorīdu (5 g, 32 mmol, 1 ekvivalents) un maisījumu maisīja 63 stundas 5-20 °C temperatūrā. Maisījumu atdzesēja līdz 5°C un pievienoja 1 N sālsskābi (30 ml). Tetrahidrofurānu iztvaicēja zem pazemināta spiediena un ekstrahēja ar etilacetātu (50 ml). Organisko slāni mazgāja secīgi ar 1 N sālsskābi (30 ml), ūdeni (10 ml), piesātinātu nātrija hidrogēnkarbonāta ūdens šķīdumu (30 ml) un ūdeni (10 ml). Šķīdinātāju iztvaicēja zem pazemināta spiediena, lai iegūtu etil 3-okso-4-fenil-4-butanoātu gaiši dzeltenas eļļas veidā (5,82 g, iznākums: 86 %).
Bet vai kāds ir strādājis ar šo
Un vai ir kāds veids, kā izmantot fosforu vai citronu?

Es dzirdēju, ka Cas 718-08-1 ir arī Bmk, nevis Pmk.
Bet ir jaunais Pmk, kuram ir tāda pati kušanas metode kā vecajam 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.
