Abstract: Microwave-assisted synthesis(MAS) was integrated with macroporous resin catalysis (MRC) to prepare isopropyl cinnamate from cinnamic acid. The preparation process was investigated and the optimum synthetic conditions were as follows: cinnamic acid 2 g, molar ratio of cinnamic acid to isopropyl alcohol 1:10, reaction temparture 105℃, microwave power 400W, CAT-601 resin as catalyst, dose of macroporous resin 25 % of the reagents, reaction time 12.5 min. The yield of isopropyl cinnamate by the new developed process was 39.2%. The catalytic property of regenerated catalyst was stable.

Key words: isopropyl cinnamate, microwave-assisted synthesis, catalysis
