| Abstract: | Isopentyl cinnamate was synthesized by using PW12 heteroply acids and its springly solubleCe(III ), AI(III ) salts as catalyst. The reaction take was reduced. It was 2 h. Yields of the ester were> 95% for catalysts used for the first time. The technological process is simple and these sparing solublesalts can be reused as catalyst for many times. It is possible to decrease the comsumption and the corrosion behavior of catalysts. |
