Cas 718-08-1

Sinteza etil 3-okso-4-fenil butanoata je naslednja: Monoetilmonokalijev malonat (12,9 g, 2,3 ekvivalenta) smo zmešali s tetrahidrofuranom (200 ml) in zmes ohladili na 5 °C. Dodana sta bila trietilamin (8,2 g, 2,5 ekvivalenta) in magnezijev klorid (8,62 g, 2,8 ekvivalenta), zmes pa je bila mešana pri 5 do 20 °C 3 ure. Reakcijsko zmes smo ohladili na 5 °C. Fenakil klorid (5 g, 32 mmol, 1 ekvivalent) je bil dodan postopoma in zmes je bila mešana 63 ur pri 5 do 20 °C. Mešanico smo ohladili na 5 °C in dodali 1 N klorovodikovo kislino (30 ml). Tetrahidrofuran je bil uparjen pod znižanim tlakom, ekstrakcija pa je bila izvedena z etil acetatom (50 ml). Organsko plast smo zaporedno izpirali z 1 N klorovodikovo kislino (30 ml), vodo (10 ml), nasičeno vodno raztopino natrijevega hidrogenkarbonata (30 ml) in vodo (10 ml). Topilo smo uparili pod zmanjšanim tlakom, da smo dobili etil 3-okso-4-fenil butanoat kot bledo rumeno olje (5,82 g, izkoristek: 86 %).
Ali se je kdo ukvarjal s tem
In ali obstaja kakršen koli način na fosforju ali limoni

Slišal sem, da je Cas 718-08-1 tudi Bmk in ne Pmk.
Obstaja pa novi Pmk, ki ima enako metodo taljenja kot stari 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.
