性质描述: 白灰片状结晶。熔点227.5-229℃。
生产方法: 将异丙基甲苯经氧化、溴化而得。1.异丙基甲苯氧化将硝酸和对异丙基甲苯加入反应锅中,慢慢升温,至80-90℃反应4h,90-95℃反应6h。冷却,上层酸水可以套用。下层固体物用水洗后,过滤。滤饼加甲苯,加热回流半小时。趁热过滤。滤液冷至室温以下。将结晶滤出,在100℃以下干燥,得对甲基苯甲酸,熔点180-181℃。收率50%以上。对甲基苯甲酸也可以由对二甲苯氧化而得。在环烷酸钴存在下,二甲苯用空气氧化,在110-115℃反应20h,冷至室温,过滤,滤饼用二甲苯洗涤,干燥即得。此法收率40%。2.溴化将对甲基苯甲酸加入反应锅与氯苯溶解,加入溴素慢慢加热回流。反应结束时,冷至70℃,排尽溴化氢,继续冷至室温以下,过滤,滤饼用氯苯洗涤,干燥,得对溴甲基苯甲酸。收率75%以上。
用途: 医药中间体。
