Abstract
Objective The microwave assisted synthesis(MAS) was integrated with macroporous resin catalysis(MRC) to prepare isobutyl cinnamate from cinnamic acid.MethodsThe preparation processes were investigated under different conditions.ResultsThe optimum synthetic conditions were 2 g cinnamic acid,microwave power was 600 W,reaction temperature was 115℃,reaction time was 14 min,mass percent of macroporous resin was 30%,the molar ratio of cinnamic acid to isobutyl alcohol was 1:7,and the yield of the new process was 89.3%.ConclusionThe new developed technology is rapid,economical and has no pollution.
