摘　　要：以一硝基二甲苯为原料，以骨架镍为催化剂，在醇相溶剂中，用液相加氢法替代铁粉还原法，制备二甲基苯胺，成功地完成了多个品种的小试和扩试，积累了重要的工艺参数。其中主要的２，３—二甲基苯胺还进行了批量工业化生产。Using mononitro dimethyl benzen as raw material and skeletal nickel as catalyst,dimethyl aniline have been prepared by liquid phase hydrogenation method which replaces iron powder reduction method in alcohol solvent.Small or expanded experements of many kinds of dimethyl benzennamine have been finished successfully,and the important technology parameters have been accumulated.It is very important that 2,3-dimethyl aniline have been produced in industry with whole quantity.
