【摘要】 芳香硝基化合物在加氢催化剂存在下与氢、醇反应，可直接制得Ｎ－单烷基芳胺．研究了在雷尼镍（Ｒａｎｅｙｎｉｃｋｅｌ）催化下间硝基甲苯还原—烷基化直接制Ｎ－乙基间甲苯胺的工艺，通过ＧＣ－ＭＳ对反应产物进行了分析，证明该工艺兼有高转化率和高选择性的优点更多还原

【Abstract】 N monoalkyl aromatic amines are synthesized in high conversions and selectivities from corresponding nitro compounds by reacting with hydrogen and alcohol in the presence of hydrogenation catalyst. The synthetic techniques of N ethyl m toluidine from m nitrotoluene and ethanol by catalysis of Raney nickel are studied. The reaction products are analysed by GC MS. The reaction mechanism of reductive alkylation is discussed.更多还原
