摘要
采用水蒸汽蒸馏回收除焦残液中的一硝基甲苯,用脱色、结晶提纯2,4二硝基甲苯的方法,取得了一硝基甲苯总回收率大于95%、提纯后2,4二硝基甲苯纯度在995%以上的效果。
This paper reports a method of using steam distillation to recover mononitrotoluene (MNT) from residual liquid and decoloration,crystallization to refine 2,4-dinitrotoluene (2,4-DNT).The overall recovery of MNT was >95% and the purity of refined 2,4-DNT was >99.5%.
