补充资料:邻氯氯苄
分子式:C7H6Cl2
分子量:161.03
CAS号:611-19-8

性质:液体。熔点-17℃,沸点213-214℃(217℃),94-95℃(1.33kPa),相对密度1.2699(0/4℃),折射率1.5895,闪点82℃。

制备方法:以邻甲苯胺为原料,经重氮化置换,氯化而得。将邻甲苯胺,盐酸,水混合,冷至0-5℃,将亚硝酸钠滴入,进行重氮化反应。在迅速搅拌下,于0℃倒入氯化亚铜,自然升温至20-25℃,最后升至60-65℃,保温20min后冷却,静置、分层、洗涤、蒸馏,得到邻氯甲苯。邻氯甲苯与三氯化磷混合,于130-140℃通氯,得邻氯氯苄。

用途:有机合成原料,医药工业用于制兴奋药酶抑宁等。
