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%.
