【摘要】 以五硫化二磷为原材料,在催化剂三乙胺存在下,与无水乙醇反应合成乙基硫化物,再与氯气反应,最后经硫化钠和氢氧化钠的混合物精制,得到纯度≥99%的O,O-二乙基硫代硫酰氯,总收率达到89%以上。更多还原

【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 purlified by mixture solution of sodium sulfide and sodium hydroxide. The purity of O,O-diethyl thiophosphoryl chloride could reach 99% and the production rate could be above 89%.更多还原
