摘要
在一定的催化剂作用下,以3,5,6一三氯吡啶-2-醇钠和O,O-二甲基硫代磷酰氯为原料,以水为溶剂合成甲基毒死蜱。确定了适宜的工艺条件,产品含量可达97.5%,总收率为96.2%(以3,5,6一三氯吡啶-2-醇钠计)。
In the role of a catalyst, using 3,5,6-trichloropyridin-2-ol sodium and O,O- dimethyl thiophosphoryl chloride as raw materials and water as solvent synthesis of chlorpyrifosmethyl. To determine the appropriate process conditions, product content of up to 97.5%, with a total yield of 96.2% （by 3,5,6-trichloropyridin-2-ol sodium idea）.
