三氯杀螨醇

三氯杀螨醇用途

【用途一】
非内吸性杀螨剂，用于防治多种作物的螨类
【用途二】
广泛用于棉花、果树、茶叶等农作物防治红蜘蛛
【用途三】
广谱性杀螨剂，对成螨、幼若螨和卵均有效。有较好选择性，不伤害天敌，对蜂娄安全。对害螨以触杀为主，残效期长，无内吸作用。用于防治棉花、果树、花奔多种害螨。多年使用易产生抗性。使用时将20%乳油对水800～1500倍液均匀喷雾。初用或气温高时，可扩大稀释倍数。
【用途四】
用作杀螨剂。主要用于防治棉花、果树、玉米、小麦的红蜘蛛，有触杀和胃毒作用，兼杀成虫，并有一定杀卵效果。一般使用浓度为稀释800-1500倍，防效在90%以上，持效期10-20d。该品对茄子和红玉苹果有药害。
【用途五】
用作杀螨剂。主要用于防治棉花、果树、玉米、小麦的红蜘蛛，有触杀和胃毒作用，兼杀成虫，并有一定杀卵效果。一般使用浓度为稀释800-1500倍，防效在90%以上，持效期10-20d。该品对茄子和红玉苹果有药害。校准仪器和装置；评价方法；工作标准；质量保证/质量控制；其他。

三氯杀螨醇制备

将滴滴涕氯化，然后酸性水解得三氯杀螨醇。
1.氯化将滴滴涕以二氯乙烷为溶剂，加1%偶氮二异丁腈作催化剂，于80～90℃通入氯气反应2h，然后减压蒸出溶剂。

2.水解氯化产物水解反应在对甲苯磺酸33%、硫酸33%、水33%的混合酸性介质中进行，并以芳基磺酸或低级烷基磺酸为促进剂，于135～150℃反应5～6h，而后入适量低沸点溶剂二氯乙烷和水，形成油水两层，提取油层，并用稀碱液和水洗涤后，减压蒸出溶剂，即得三氯杀螨醇原药。
