摘要
介绍了聚氨酯工业重要原料2,6-二硝基甲苯的多种合成方法。重点论述了从工业二硝基甲苯中分离出高纯度2,6-二硝基甲苯的方法,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 synthetic methods of dinitrotoluene were described . It is important that separating high pure dinitrotoluene from crude dinitrotoluene and the problems in that methods were discussed. The importance and the inexorable trend of study on the new nuisanceless separation methods were pointed out.
