Ethyl dichlorothiophosphate Use and Manufacturing
The preparation method is to meter the fresh phosphorous trichloride into the reaction kettle, cool to -2°C, slowly add anhydrous ethanol dropwise, control the reaction temperature (0±2)°C, with negative pressure during the reaction, and extract the generated Hydrogen chloride, after the reaction is completed, move to the distillation pot, first distill the front fraction, and continue to distill to obtain the product.
O-ethyl thiophosphoryl dichloride is referred to as ethyl dichloride, which is used to synthesize the organophosphorus insecticide isopropylamine phosphorus (ethylisosphosphoryl) and the herbicides glufosinate and glufosinate.
