高纯度2,6-二硝基甲苯制备的研究进展

Advances in the Preparation of High Pure 2,6-Dinitrotoluene

介绍了多种2,6-二硝基甲苯的合成方法。重点论述了从工业二硝基甲苯中分离出高纯度的2,6-二硝基甲苯,且分析了目前各种方法中存在的问题。指出了开发新的无公害分离方法的重要性和必然趋势。

Many methods synthesizing for dinitrotoluene were described. Separating high pure dinitrotoluene from crude dinitrotoluene was intraduced in detai is, and the problems in these methods were discussed. The importance and the inexorable trend of the study on the new nuisanceless separation methods were point out.
