摘要
以纳米复合磷钨酸为催化剂,以桂酸和丁醇反应合成桂酸丁酯.结果表明,纳米复合磷钨酸是合成桂酸丁酯的良好催化剂;酸醇物质的量比为1:2.0,催化剂用量为1.2 g/0.05 mol桂酸,带水剂环己烷为10 mL,反应时间为100 min条件下,桂酸丁酯的酯化率可达94%.
Butyl cinnamate is synthesized from cinnamic acid and butyl alcohol using nanometer comptex tungstophosphoric acid as catalyst. The results show that nanometer complex tungstophosphoric acid is a good catalyst for synthesizing butyl cinnamate. The yield of butyl cinnamate is up to 94% when molar ratio of cinnamic acid to butyl alcohol is 1：2.0, amount of catalyst is 1.2g/0.05mol cinnamic acid, water-carrying agent is 10 mL,and reaction time is 100min.
