Direct Synthesis Of Dichlorvos
Aug 13, 2018

Using trimethyl phosphite and trichloroacetaldehyde reaction, remove a molecule of chloromethane and synthesize, known as perkow reaction. Operation will trimethyl phosphite (or chloral) at room temperature drops to the chloral trimethyl phosphite (or) the heat energy that is released by cooling, control and temperature 60 ℃, drops, in 70 ℃ heat 90 min, trimethyl phosphite and chloral ratio of 1:1, yield of 94.53%.
