1,4-二氯苯上游产品

1,4-二氯苯下游产品

苯定向氯化或从氯苯生产中回收。

1.苯定向氯化将苯置于氯化反应器中，加苯重量的0.1%-0.6%的硫化锑，通入氯气，控制氯化温度在20℃左右，氯化30-45分钟，加入苯磺酸定向催化剂，然后再通入氯气，当二氯苯晶体析出时，将反应液加热到50-60℃，再缓速通氯气直到反应液增重理论量的95%左右为止，收率70%-75%。由于苯氯化产物组分较多，工业制备的关键是对二氯苯选择适当的分离，精制方法。分离和精制对、邻位二氯苯的方法较多。精馏法较结晶法难度大、能耗高，不利于产物的稳定和设备的防腐蚀。重结晶法已发展到连续分级结晶法。乳化法利用表面活性物质进行乳化而分离，此法具有操作简单，能耗低，效率高和环境污染少等优点，对其研究日见增多，发展较快。

2.由氯苯生产过程中回收将氯苯精馏塔底物，经真空蒸馏蒸出混合二氯苯，在结晶器中进行结晶而得较纯的对二氯苯。
