摘要
着重研究了以铁—盐酸为还原剂,还原2,6-二硝基甲苯制备2,6-二氨基甲苯标准物质的过程中,反应介质、温度、搅拌速度以及分离精制阶段对2,6-二氨基甲苯的产率和纯度的影响。
The effect of reaction medium,temperation,stirring rate and the stage of refinement on the output rate and purity of 2,6-diamino toluene was studied when the reducing agent of iron-hydrochloric acid reduced 2,6-dinitrotoluene to 2,6-diamino toluene.
