摘要
充分利用3,4-二氯苯胺与间氯苯胺的熔点差别以及在甲醇中的溶解度特性,将低含量3,4-二氯苯胺提纯为合格的3,4-二氯苯胺,达到了能耗小、成本降低的生产效果。
By making full line in methanol and solubility dichloroaniline, the production use of 3,4 - Dichloroaniline and the melting point of difference between chloral ani- characteristics of low content in 3,4 - Dickloroaniline purification for qualified 3,4 - effect of lower energy consumption and cost was achieved.
