Diethylchlorthiofosfat - Preparation Method
Open Data Verified Data
- O-ethyl thiophosphoric acid dichloride is produced by the reaction of trichlorothiophos with anhydrous ethanol, which is then mixed with an excess of anhydrous ethanol, and alkali powder is added to produce 0, O′-diethyl thiophosphoric acid dichloride.
- phosphorus pentasulfide method the reaction of phosphorus pentasulfide with anhydrous ethanol produces 0,O'-ethyl dithiophosphoric acid, and then reacts with chlorine at low temperature to produce 0,O: diethyl thiophosphoryl chloride.
- in the ethanol alkali powder method, the dichlorides are generated by the reaction of the phosphorus trichlorosulfon with excess anhydrous ethanol; The dichlorides are mixed with the excess anhydrous ethanol, and the alkali powder is added to generate ethyl chloride.
- The sodium ethoxide method is derived from the interaction of sodium ethoxide with phosphorus trichloride.
