间歇氯化生产氯乙酸工艺的改进

Innovation on chloroactic acid process by batch chlorinated method

介绍了近十年国内有关醋酸间歇氯化法生产氯乙酸工艺的改进情况。包括以多孔分布器代替单孔通氯设备;对低沸物进行蒸馏及改进结晶工艺。

The domestic innovation status of the process of chloroactic acid by batch chlorinated method during ten years were introduced, including porous distributor instead of single orifice uints, distillation of low-boiler and the innovation of crystallization process.
