- 方法二:1.由对甲苯胺经重氮化、置换而得。将对甲苯胺和盐酸加入反应锅中搅拌加热,至60℃溶解后,冷却至15℃以下,滴加亚硝酸钠溶液。到达终点后继续搅拌0.5h。加入氯化亚铜盐酸溶液,在室温搅拌3h。然后升温至60℃保持0.5h,冷至室温静置分层,弃去酸水层,用水洗至中性,过滤,得对氯甲苯。反应所用的氯化亚铜可按下法制备:将硫酸铜和氯化钠加入水中,搅拌加热至40℃溶解,加入液碱和焦亚硫酸钠溶液,析出沉淀物,静置分层,分去上层废液,沉淀用水浸洗,加盐酸溶解,即得氯化亚铜盐酸溶液。原料消耗定额:对甲苯胺(95%)897kg/t、亚硝酸钠533kg/t、盐酸2435kg/t。2.由甲苯进行芳环氯化制得。

- 方法一:其制备方法有以下几种。 重氮化法 在反应釜中加入工业用盐酸和对甲基苯胺,釜内温度降至0℃,使对甲基苯胺生成盐酸盐,搅拌,加入亚硝酸钠溶液,使其发生重氮化反应,温度维持在0~5℃,时间约30min,重氮化反应完成后,将其加入到搅拌的氯化亚铜溶液中,逐渐升温到室温,在室温下搅拌2.5~3h,再加热到60℃,该反应物逐步分解成为氮气和对氯甲苯,然后用水蒸气蒸馏,收集对氯甲苯与水的混合液,进行分层,有机层用酸洗涤,再用水洗涤,干燥,进行蒸馏,收集158~162℃馏分为对氯甲苯,收率约70%~79%。 直接氯化法 经食盐干燥脱水的甲苯经计量槽计量后进入甲苯氯化反应器,计量后的氯气由反应器的底部通入,甲苯与氯气在一定温度下,以三氯化铁为催化剂进行苯环氯化,生成一氯甲苯氯化液,该氯化液用氮气赶去余气和氯化氢,再进行粗蒸,得到对氯甲苯和邻氯甲苯的混合物,其对、邻比随着催化剂和反应条件不同而不同,一般对、邻比为55∶45。 对氯甲苯和邻氯甲苯的分离可用精馏法、分子筛吸附法、精馏结晶联合法等。精馏结晶联合法,能耗较低,得到的对氯甲苯和邻氯甲苯含量均较高,如采用降膜冷冻结晶法,对氯甲苯的含量可达
