性质描述: 无色油状液体。沸点87℃(1.33×10-3kPa),相对密度1.250(20/4℃),折光率1.5698。蒸气压为4×10-6kPa(20℃),1.1×10-5kPa(30℃),2.66×10-5kPa(40℃)。溶于甲醇、乙醇、丙酮、甲苯、二甲苯、氯仿及其他许多有机溶剂和甘油。在室温水中的溶解度为54-56mg/L。纯品无臭,工业品有大蒜气味。对光和大碱性稳定,热稳定性可达210℃。
生产方法: 由间甲酚与二甲基二硫反应制备中间体对甲硫基间甲酚,再与O,O-二甲基硫代磷酰氯反应得到倍硫磷。1.对甲硫基间甲酚的制备将间甲酚(或混甲酚)、二甲基二硫按2:1(重量比)配料,加入反应锅,搅拌冷却至10-15℃,开始滴加浓硫酸。在1h左右滴完(用量与二甲基二硫等重量),在10-15℃继续反应3h。静置分层,弃去下层废酸。有机层用10%碳酸钠溶液中和,再用水洗涤于pH7-8。减压蒸馏回收未反应的二甲基二硫和甲酚,所剩物料即中间体对甲硫基间甲酚。2.倍硫磷的制备将20%的氢氧化钠溶液加入反应锅,搅拌冷却至25℃以下,投入上述制备的中间体,然后在10-20℃均匀滴加O,O-二甲基硫代磷酰氯,约30-40min滴完,三种物料的投料量按摩尔比为1.3:1:1.2。缓缓升温到60℃,保温2h,反应过程中检查pH变化情况,当pH<9时,应补加氢氧化钠溶液。反应结束后,降温至45℃,加氢氧化钠溶液洗涤,再用水洗涤,静置分层。取下层有机层减压脱水,冷却,过滤,得倍硫磷原油,含量90%,收率90%。原料消耗定额:三氯化磷(97%)1030kg/t、甲醇(99%)900kg/t、混甲酚(50%)1150kg/t、硫磺粉(95%)280kg/t、硫化钠(52%)1240kg/t、硫酸二甲酯(96%)920kg/t。
用途: 倍硫磷是对人、畜低毒的有机磷杀虫剂,对多种害虫有效,主要起触杀的胃毒作用,残效期长,对螨类效果不如甲基对硫磷,主要用于防治大豆食心虫,棉花害虫,果树害虫,蔬菜和水稻害虫,用于防治蚊,蝇,臭虫,虱子,蟑螂也有良好效果。
