摘要
本文研究了以3,5,6-三氯吡啶醇钠和 O,O-二乙基硫代磷酰氯为原料,采用水溶剂法合成毒死蜱的工艺,报道了一种用三元复合催化剂催化合成毒死蜱的新方法,探讨了适宜的工艺条件,毒死蜱的收率,含量分别达到95%和97%以上,并采用 IR、~1H NMR、^(13)C NMR 对该化合物的结构进行了表征。
The Preparation of ehlorpyrifos was studied utifizing 3, 5, 6-triehloro -2-pyridinol sodium and O, O -diethyl phosphorochloridothioate via aqueous phase as the starting materials. A new method of the synthesis of ehlorpyrifos was reported by using three compound catalyzers. The optimum reaction conditions were investigated. The yield and purity of ehlorpyrifos were over 95% and 97% respectively, structure of synthesized compound was confirmed by IR、^1H NMR、^13C NMR.
