| Abstract: | Synthesis of isoamyl cinnamate from cinnamic acid and isoamyl alcohol with nanometer H3PW12O40/SiO2 as catalyst is studied in this article, and the results shows nanometer H3PW12O40/SiO2 is a good catalyst for synthesizing isoamyl cinnamate. The oplimal conditions are found as follows： molar ratio of cinnamic acid to isoamyl alcohol is 1 ： 2.5, the weight of catalyst was 0.6 g/0.05 mol cinnamic acid, the reaction time is 3 h, yield is about 96.2%. |
