| Abstract: |
| The methyl cinnamate was synthesized by using high pressure microwave,and TiSiW12O40/TiO2 is used as catalyst.The optimum reaction conditions were determined as follows.The mole ratio of methyl alcohol to cinnamic acid is 5:1.The quantity of catalyst is 2.0% of feed stock.The power of microwave is 729 W.The radiating time of microwave is 3 min.The average yield is 97.4%. |
