在O.O一二甲基二硫代磷酸(简称硫化物)的生产过程中,难免有一些甲基中性油生成,估计全国每年排放了数千吨.为了节约宝贵的化工原料,消除对环境的污染,应该寻找合理的途径,予以有效利用.O.O一二甲基硫代磷酰氯(简称氯化物)是农药生产中使用很广的重要中间体,它用于合成多种高效低毒有机磷农药.国外资料报导,用苯、甲苯、四氯化碳、二氯甲烷等作溶剂,O.O.O一三甲基硫逐磷酸酯[(CH_3O)_3PS]和O.O.S一三甲基二硫代磷酸酯[(CH_3O)_2
In the production of OO-dimethyl dithiophosphoric acid (hereinafter referred to as sulfide), it is inevitable that some of the methyl-neutral oil production is estimated that the country discharges thousands of tons annually In order to save precious chemical raw materials and eliminate the environmental Pollution, should find a reasonable way to make effective use of .OO a dimethylthiophosphoryl chloride (referred to as chloride) is widely used in the production of pesticides is an important intermediate, which is used to synthesize a variety of high efficiency and low toxicity of organophosphorus pesticides Foreign data reported that benzene, toluene, carbon tetrachloride, dichloromethane and other solvents, OOO a trimethyl phosphorothioate [(CH_3O) _3PS] and OOS a trimethyl phosphorodithioate [( CH_3O) _2
