| Abstract: | The modified synthetic process of O,O-diethyl thiophosphoryl chloride was intrcduced in this paper. The phosphorus pentasulfide reacted with absolute alcohol in the existing of triethylamine, then the chlorine was added. The product was purified by mixture solution of sodium sulfide and sodium hydroxide. The purity of O,O-diethyl thiophosphoryl chloride could reach 99% and the rate could be above 89%. |
