Phosphorodithioic acid, O,O-dimethyl ester, ammonium salt (1:1) Use and Manufacturing

Methods of Manufacturing

The preparation method is to use methyl sulfide and ammonium bicarbonate to prepare methyl sulfide ammonium salt. Under stirring, put 20kg of kerosene, 500kg of water, and 300kg of ammonium bicarbonate into the reaction kettle, and finally add methyl sulfide dropwise, control the pH of the reaction solution = 6-7, stop stirring, let stand for 20min, filter, stand for layering , An aqueous solution of methyl sulfide ammonium salt is obtained. NaHCO3, NaOH, etc. can also be used instead of NH4HCO3 to prepare methyl sulfide sodium salt.

Uses

Dimethyl phosphorodithiolate derivatives used as insecticides.
