CAS: 1712-70-5
分子式: C9H9Cl
分子量: 152.62
沸点: 205℃
中文名称: 
4-氯-a-甲基苯乙烯
对氯-α-甲基苯乙烯
4-氯-α-甲基苯乙烯
英文名称: 
4-Chloro-methylstyrene
2-(4-Chlorophenyl)propene
4-Chloro-α-methylstyrene

性质描述: 该品相对密度1.065(20/4℃),沸点205-207℃,折光率1.5547,闪点73℃。
生产方法: 由对二氯苯经加成、水解、消除而得。1.加成、水解将镁屑和四氢呋喃加入反应锅搅拌加热,在60℃加引发剂碘甲烷。开始激烈反应时加对二氯苯和四氢呋喃的混合液,回流2h。冷至15℃,慢慢加入丙酮,搅拌后静置过夜。然后加氯化铵冰水、浓盐酸,在20℃以下水解。取油层用硫酸洗涤,再用水洗至中性,加无水氯化钙干燥,滤去干燥剂后减压蒸馏,得对氯苯二甲基甲醇。2.消除将粉碎好的硫酸氢钾投入带分馏柱的反应锅内,加热至210-220℃,熔融,在减压下滴加对氯苯二甲基甲醇。收集120-140℃(5.33-6.67kPa)馏分,再重蒸一次,收集80-90℃(2.0kPa)馏分,即得成品。
用途: 有机中间体。
