摘　　要：以月桂醇和二甲胺的胺化反应为对象 ,对以 Ca CO3为载体的 Cu、Ni体系中加入 Mg后的催化性能进行了研究 ,发现加入 Mg可有效提高催化剂的选择性 .通过用 XPS分析 Ni的价态发现 Mg能够阻碍催化剂中氧化态 Ni的还原 ,使 Ni元素保持有相对高的净核电荷数 .Ni的净核电荷数越高 。The effects of addition of Mg to CaCO 3 supported Cu Ni catalyst in catalytic amination of dodecyl alcohol with dimethylamine have been investigated. It is found that Mg can effectively promote the selectivity of the catalyst due to its prohibition effect on the reduction of Ni. The XPS results of the catalysts revealed that Ni in the catalyst with added Mg has a relatively higher positive charge. The higher the positive charge of Ni, the higher the selectivity of the catalysts.
