敌敌畏

敌敌畏用途

用途一：敌敌畏具有熏蒸、胃毒和触杀作用，对咀嚼式口器害虫和刺吸式口器害虫均有良好的防效。敌敌畏的蒸气压较高，对害虫有很强的击倒力。施用后易分解、残效期短。使用方法多种多样，简便易行。适用于防治棉花、果树、蔬菜、甘蔗、烟草、茶、桑等作物上的多种害虫。对蚊、蝇等家庭卫生害虫以及仓库害虫米象、谷盗等也有良好的防治效果。
用途二：高效、广谱杀虫剂，具有胃毒、触杀和强烈的熏蒸作用，由于蒸气压较高，对咀嚼口器和刺吸口器害虫具有很强的击倒力。主要用于防治卫生害虫，农林，园艺害虫，粮仓害虫，如：蚊、蝇、咀、孑孓、臭虫、蟑螂、黑尾叶蝉、黏虫、蚜虫、红蜘蛛、水稻浮尘子、食心虫、梨星毛虫、桑蟥、桑粉虱、桑尺蠖、茶蚕、茶毛虫、马尾松毛虫、柳青蛾、青虫、黄条跳甲、菜螟、造桥虫、斜纹夜蛾、苹果巢蛾等。用药量为80%乳油1000～2000倍液喷雾。对高梁易产生药害，对豆类、玉米、柳树也较敏感。
用途三：具有熏蒸、胃毒和触杀作用，对咀嚼口器害虫和刺吸口器害虫均有良好的防治效果
用途四：可用作家庭和公共场所的熏蒸剂，也适用于防治棉花、果树、蔬菜、烟、茶、桑等作物上的多害虫

敌敌畏合成路线

详细合成路线

敌敌畏上下游产品

敌敌畏上游产品

敌敌畏下游产品

敌敌畏制备

1.由敌百虫在溶剂中经碱解制得。

2.由亚磷酸三甲酯与三氯乙醛进行珀考夫重排缩合制得。

3.由敌百虫在溶剂中经碱解制得，反应结束静置分层，油层经薄膜蒸发回收溶剂，并得敌敌畏原油。或者由亚磷酸三甲酯与三氯乙醛进行柏尔柯夫（Ｐｅｒｋｏｗ）重排缩合制得。

4.脱氯化氢法：敌百虫在碱性条件下脱氯化氢生成敌敌畏。操作时控制敌百虫水悬浮液含量为25%（也可用精制敌百虫母液，加适量的敌百虫固体），敌百虫与碱的配比为1∶（1.35～1.4），采用水和甲苯（二甲苯、苯）两个溶剂，反应温度50～60℃，反应时间20～25min，终点pH值7～8。这一反应使α-羟基膦酸酯重排成磷酸酯。反应结束静置分层，油层经薄膜蒸发回收溶剂，并得敌敌畏原油。

5.制备或来源：在搅拌下，将熔融的敌百虫和水加入碱解釜中，在加入溶剂苯，然后加入30%液碱，在约2～3分钟内加完，温度不超过65℃，控制PH值，如酸性即补加碱，加完后搅拌0.5小时，将反应物送入分液器静置15～30min，分去水层，苯层再静置15min，进一步分去水，所得敌敌畏苯油在减压下加热，流经薄膜蒸发器，脱去苯和水，得原油。也可采用亚磷酸三甲酯与三氯乙醛进行珀考夫重排缩合制得，亚磷酸三甲酯由三氯化磷与甲醇反应制得。制剂有：原油，50%、80%乳油，50%油剂，20%塑料块缓释剂，15%缓释颗粒。
备注：残効期短。饱和的敌敌畏水溶液转化成磷酸氢二甲酯和二氯乙醛，其水解速度每天约3%，在碱性溶液中水解更快。对铁和软钢有腐蚀性，但对不锈钢、铝、镍、Hastelloy13和Teflon无腐蚀性。对热稳定。雄、雌大白鼠急性经口毒性LD50分别为80、56mg/kg，雄、雌大白鼠急性经皮毒性LD50分别为107、75mg/kg。鲤鱼LC50为4mg/L。米、麦、杂粮、果实、蔬菜、茶允许残留量为0.1mg/kg，草莓为0.3mg/kg。ADI为0.03mg/kg。
