摘要
以内桂酸和正丙醇为原料，用钼镍粉催化剂催化合成肉桂酸正丙酯。经实验确定了最佳条件：n（n-正丙醇）／n（肉桂酸）=1．5，催化剂用量为反应物总质量的4％，反应时间为4h,反应温度85～95℃，肉桂酸正丙酯收率80％以上，催化剂可重复使用，催化活性变化不大。
N-propyl cinnamate was synthesized by the asterification of mopanal with cinnamie aeid in the presence of a new erviromentally friendly Catalyst ; Md-Ni, the factors influencing the synthesis and the best conditions are ： n（alcohol）/n（cinnanic） = 1.5 and the guantity of catalyst is egual to 4% of feed stock. The reaction temperature is 85 -95℃, and the reaction time is 4h. Mo-Niis and excellent catalyst forsynthesizing n-prpyl cinnamate and its yield can reach over 80%.
