Quinalphos Use and Manufacturing

Methods of Manufacturing

Using o-phenylenediamine, chloroacetic acid and hydrogen peroxide as raw materials, the intermediate 2-hydroxyquinoxaline is prepared, and then condensed with O, O-diethylthiophosphoryl chloride in acetonitrile and potassium carbonate to obtain quinosulfide phosphorus. Raw material consumption quota: 1200kg/t o-phenylenediamine, 1150kg/t chloroacetic acid, 800kg/t O, O-diethylthiophosphoryl chloride.

Uses

Quinalphos is used to control both chewing and sucking insects and mites in a large number of different crops.
