Diethylphosphorodithioate Usage And Synthesis

Chemical Properties

Diethylphosphorodithioate is a colorless oily liquid, and the industrial grade is a brown liquid. It is flammable, has a foul odor, soluble in water and organic solvents, decomposes at high temperature, and highly corrosive.

Uses

Diethylphosphorodithioate is an important pesticide intermediate, which can be used for the preparation of organophosphorus pesticides such as phorate, terbution, phosphine, etc.

Definition

ChEBI: Diethyl dithiophosphate is an organic thiophosphate.

Synthesis

Diethylphosphorodithioate was prepared by phosphorus pentasulfide stirred in absolute ethanol at 50～65℃ for 30-45min.
