性质描述: 浅黄色油状液体。沸点140-145℃(1.33×10-2kPa),118℃(6.65×10-3kPa),97℃(5.32×10-3kPa),相对密度为1.3227(25/4℃),折光率1.5528(25℃),20℃的蒸气压(8×10-7kPa)。能与乙醇,乙醚,丙酮,苯,二甲苯,氯仿,四氯化碳,植物油等互溶,微溶于石油醚和煤油,难溶于水。在高温与碱性条件下易分解,铁、锡、铝、铜、铅等金属会促进分解。蒸馏会引起异构化。
生产方法: 由 O,O-二甲基硫代磷酰氯与4-硝基间甲酚([2581-34-2])在碱性条件下缩合而得。将甲苯加入缩合反应锅,搅拌下投入4-硝基间甲酚,碳酸钠和氯化亚铜,在95-97℃时投入O,O-二甲基硫代磷酰氯,在90℃以上反应3h,然后过滤,取甲苯层依次用氢氧化钠溶液、水洗涤,减压蒸馏回收甲苯后得杀螟松原油,含量90%。当采用摩尔配比4-销基间甲酚:O,O-二甲基硫代磷酰氯:碳酸钠=1:1.1:1,甲苯用量约为4-硝基间甲酚的3倍(重量),氯化亚铜约为4-硝基间甲酚的2%(重量)时,杀螟松收率95%以上。所得原油有效成分含量优级品不低于93.0%,一级品≥85.0%原料消耗定额:间甲酚550kg/t、硝酸(100%)860kg/t、三氯硫磷(100%)1240kg/t、甲醇600kg/t。
用途: 杀螟松对水稻、大豆、棉花、果树、蔬菜等多种作物害虫均有良好的防治效果,尤为防治水稻螟虫特效药。如大螟、二化螟、三化螟、稻飞虱、稻叶蝉、蚜虫、红蜘蛛、棉铃虫、大豆食心虫、茶天蠖等,每亩施用50-75g(有效成分),防治效要良好,但杀螨卵效果较小。该品对十字花科蔬菜有时发生药害。
