用于月桂醇胺化的Cu-Ni-Mg三元催化剂的研究
摘要:
以月桂醇和二甲胺的胺化反应为对象,对以CaCO3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,催化剂的选择性越好.

The Cu-Ni-Mg Catalysts for Catalytic Amination of Dodecyl Alcohol
Abstract:
The effects of addition of Mg to CaCO3 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.
