摘要： 制备了一系列不同投料比例(Mo/P摩尔比为0.6～2.6)的磷化钼催化剂,研究了催化剂对乙腈选择加氢反应的催化性能. 结果表明,在初始Mo/P>1.0时,催化剂表现出很高的乙胺选择性,达到80%～90%; Mo/P<1.0时,对二乙胺和三乙胺有很好的选择性,二者之和达到90%左右; 而在Mo/P=1.0时,催化剂具有最高的乙腈转化率.

Abstract: A series of molybdenum phosphide catalysts were prepared at initial Mo/P molar ratios ranging from 0.6 to 2.6. The catalytic activity of the catalysts for the selective hydrogenation of acetonitrile was studied. The catalysts with initial Mo/P ratios>1.0 have high selectivity for ethylamine (80%-90%), and for the catalysts with Mo/P ratios<1.0, the selectivity for diethylamine and triethylamine is more favorable (about 90%). When Mo/P ratio=1.0, the highest conversion of acetonitrile is attained.

Key words: transition metal phosphide, molybdenum, acetonitrile, selective hydrogenation, ethylamine
