邻二氯苯下游产品
邻二氯苯制备
由氯苯副产和用合成方法制得。
1.氯苯副产回收 无论是采用苯液相氯化法还是采用苯气相氧氯化法制造氯苯,都联产二氯苯。根据实际需求量,改变氯化工艺条件,可调节一氯苯和二氯苯的生成比例。按照目前氯苯的工艺控制条件和生产情况,氯苯与二氯苯的比例为30-35:1,工业上分离邻、对位二氯苯的方法主要有精馏法和结晶法。
2.由邻氯苯胺经重氮化、置换而得将邻氯苯胺及盐酸加入反应锅,于25℃以下混匀。冷却至0℃,滴入亚硝酸钠溶液,温度维持在0~5℃,至碘化钾淀粉液变蓝色时停止加料,得重氮盐溶液。在0~5℃下加入氯化亚铜的盐酸溶液中,充分搅拌、混匀,升温至60~70℃℃,反应1h,冷却、静置分层,油层用5%氢氧化钠和水反复洗涤,以无水氯化钙脱水、分馏,收集177~183℃馏分,即得成品。
