间硝基三氟甲苯制备
1、 由三氟甲苯经硝化而得。将浓硫酸加入反应锅内,在搅拌冷却下加入发烟硫酸及浓硝酸,加热至40℃,滴加三氯甲苯,控制温度40-45℃。加毕,在50-55℃反应3h,冷至室温,静置分去下层酸液。上层液放入5倍量冰水中,静置分层,分出的硝基物用2%碳酸钠溶液及水洗涤,即得间硝基三氟甲苯。收率接近93%。
2、 其制备方法是在反应瓶中加入浓硫酸、浓硝酸,开动搅拌,滴加三氟甲苯,控制反应温度在50℃左右,滴加完后再继续搅拌反应2 h,然后静置分层,分出废酸,有机相依次用水、碱和水洗涤至pH=7~8,粗产品中约含间位体91%、邻位体6.8%、对位体2.0%,将粗产物进行分馏得3-三氟甲基硝基苯。
