CAS: 6627-55-0
分子式: C7H7BrO
分子量: 187.03
沸点: 213-214℃
熔点: 213-214℃
中文名称: 
2-溴-4-甲基苯酚
2-溴-4-甲基酚
邻溴对甲酚
英文名称: 
2-bromo-p-creso
2-bromo-p-cresol
2-bromo-4-methylphenol
2-bromo-4-methyl-phenol
性质描述: 羽毛针状体结晶。熔点56-57℃,沸点213-214℃,102-104℃(2.67kPa),相对密度1.547(57/4℃),折光率1.5785。可溶于乙醚。
生产方法: 由2-溴-4-甲基苯胺重氮化、水解而得。将稀硫酸加到2-溴-4-甲基苯胺中,搅拌冷却,在5℃以下加入亚硝酸钠水溶液,温度保持在5℃以下,然后再加冷水、尿素和碎冰,得重氮盐溶液。再将无水硫酸钠、浓硫酸和水加热,在130-135℃分批加入重氮盐溶液,然后分批加入水进行蒸馏,所得馏出液用乙醚萃取,用10%碳酸氢钠溶液洗涤,再经无水硫酸钠干燥,过滤,滤液蒸去乙醚而得成品。另一种方法是由对甲苯酚在氯仿溶剂中直接溴化。
用途: 有机合成中间体。
