摘要
综述了国内外杀扑磷的合成路线，开发了以水合讲为原料同氯甲酸三氯甲酯、甲基硫化 物、甲醛反应合成杀扑磷的生产新工艺，一次性得到杀扑磷原药含量达９６％～９８％，以水合肼计总 收率为 ４２％。
preparation of methidathion, which is started from hydrazine hydrate, reacting with trichloromethyl chloroformate, methyl sulfide and synthesis methods of methidathion, home and aboard, are being summarized in this article. We have developed a new technology for formaldehyde. Purityobtained in one time is around 96% - 98%: and the total yield is 42 %, calculated as hydrazine hydrate.
