CAS: 25185-95-9
分子式: C7H5Cl2NO
分子量: 190.33
熔点: 148-151℃
中文名称: 
2,6-二氯苯甲醛肟
英文名称: 
2,6-Dichlorobenzyloxime
2,6-Dichlorobenzaldoxime
2,6-dichloro-benzaldehyd oxime
2,6-dichloro benzyloxime
性质描述: 白色晶体。熔点149-150℃。
生产方法: 以2,6-二氯甲苯与氯化亚砜混合,以三氯化磷为催化剂,在紫外光照射下,加热到200℃,通入氯气进行反应,同时用液碱吸收尾气,直至增加重量达理论重量为止,得2,6-二氯苄双氯,将其加入硫酸中,搅拌下加热至50-55℃,反应3h,然后分次加入盐酸羟胺,保温3h后,将反应产物缓缓加入冰水中,不停搅拌,过滤,冷水洗涤即得。
用途: 作医药中间体,用于制造双氯苯唑青霉素钠。
