第三组分对Cu-Ni脂肪醇胺化催化剂的影响

目前制备单长链烷基二甲基叔胺的主要工艺是由脂肪醇和二甲胺在脱氢 加氢类催化剂的作用下进行胺化反应。研究了加入第三金属元素组分对以Cu和Ni为活性组分、以碳酸钙为载体的催化剂选择性的影响。发现金属元素La和Ba的加入,提高了催化剂的选择性,降低了反应产物中高沸物双十二烷基甲基叔胺的含量。Al的加入却大大降低了催化剂的选择性。

Effect of third element on performance of Cu-Ni catalysts for amination of fatty alcohols

The main preparation process of long chain alkyl dimethyl tertiary amine is the catalytic amination of fatty alcohol with dimethylamine by hydrogenation dehydrogenation catalysts at present. The effects on selectivity and activity by adding La,Ba or Al to the system of Cu Ni supported on CaCO3 have been studied. It is found that the selectivity of Cu Ni catalyst is improved effectively by the adding of La and Ba, but the adding of Al reduces the selectivity of Cu Ni catalyst distinctly.
