Technology Process of Ethyl malathion

There total 3 articles about Ethyl malathion which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

methanol (67-56-1) + Diethyl maleate (141-05-9) → O,O-methyl ethyl S-(1,2-dicarboethoxy)ethyl phosporodithioate (71133-15-8) + [(dimethoxyphosphinothioyl)thio]-butanedioic acid, diethyl ester (121-75-5) + diethoxythiophosphorylsulfanyl-succinic acid diethyl ester (3700-86-5)

Guidance literature:

methanol; ethanol; With phosphorous (V) sulfide; In toluene; at 70 ℃;

Diethyl maleate; With hydroquinone; In water; at 55 ℃; for 5h;

Reference yield:

O,O-Diethyl hydrogen phosphorodithioate (298-06-6) + diethyl Fumarate (623-91-6) → diethoxythiophosphorylsulfanyl-succinic acid diethyl ester (3700-86-5)

Guidance literature:

With triethylamine; hydroquinone;

Reference yield:

O,O-Diethyl hydrogen phosphorodithioate (298-06-6) + Diethyl maleate (141-05-9) → diethoxythiophosphorylsulfanyl-succinic acid diethyl ester (3700-86-5)

Guidance literature:

upstream raw materials:

O,O-Diethyl hydrogen phosphorodithioate

diethyl Fumarate

Diethyl maleate

methanol

Downstream raw materials:

O,O-Diethyl-S-(1,2-dicarbethoxy-ethyl)-phosphorothioat
