Uses

Phosalone (2310-17-0) is non-smoking within the broad-spectrum organophosphate insecticide to kill mites. It is mainly used for cotton, fruit trees, vegetables, potatoes and a variety of economic crops, and is used to control aphids, thrips, red spider, leafhoppers, planthoppers, stem borers, Pieris and many other pests.

Production

Having the condensation of Urea with o-Aminophenol benzoxazolone , and with chlorination of SO2Cl2 to generate 6 - Chloro-oxazolone . Then take Formaldehyde and Hydrogen chloride for chlorine methylation, at last, with the O, O-Diethyl dithiophosphate sodium for condensation to get Phosalone (2310-17-0). Consumption of raw materials fixed: o-Aminophenol 550kg / t, Anhydrous ethanol 18900kg / t, Chlorine 360kg / t, Formaldehyde 120kg / t, Ammonium 710kg / t, urea 330kg / t.
