二氯苯的生产技术进展

Technology development of dichlorobenzene

介绍了二氯苯的性质、生产方法及国内生产概况,概述了二氯苯的合成及分离技术进展,指出高效定向催化技术及溶剂萃取精馏-结晶技术是今后二氯苯生产技术的发展方向。

The property, production method and production situation at home of dichlorobenzene are introduced. The research development of dichlorobenzene on the synthesis and the separation technology are summarized. This paper pointed out that the highly effective directional catalysis technology and the solvent extraction distillation-crystallization technology would be the development direction of production technology for diehlorobenzene.
