| Abstract: | The catalytic synthesis of isoamyl cinnamate by the esterifi-cation reaction of cinnamate acid and isoamylol in the presence of different acid catalysts was investigated in this paper. It was found that p-toluenesulfonic (PTS) acid was the efficient catalyst , and also the optimum conditions have been established from the ratio of reactants and the amount of catalyst used in the reaction. The yield of isoamyl cinnamate is 81% when the ratio of cinnamate acid and isoamylol was 1:1. 3, over 3% PTS catalyst. The synthetic isoamyl cinnamate was identified by IR spectrum and its physico-chemical constant, which was in agreement with the authentic sample. |
