| Abstract: | The synthesis of n-butyl cinnamate catalyzed by p-toluenesulfonic acid supported on activated carbon was investigated. The optimum conditions were as follows: the mol ratio of cinnamic acid and n-butanol was 1:2.5,the amount of the catalyst was 0.8g,the time of the reaction was 1h, when 0.02mol of cinnamic acid was used. Under this condition the yield of n-butyl cinnamate acid was up to 85.7 %. |
