| Abstract: | The synthesis of ethyl benzoate with ethyl alcohol and benzoic acid as reactants and sulfamic acid as catalyst was studied.The factors that had influence on the reaction were investigated.The results shows that the optimal conditions are(for 50 mmol of benzoic acid) using 3.0 g of catalyst and the molar ratio of ethyl alcohol to benzoic acid being 8:1 and the reaction time being 8.0 h.The yield of ethyl benzoate under such conditions is about 87.4%. |
