| Abstract: | Cinnamic acid was synthesized from benzaldehyde and acetic anhydride using solid base K2CO3 /CH3COOK as catalyst.Synthesis conditions were discussed in orthogonal experiment method.Results show that the optimum conditions of the reaction as follows: the amount of solid base is 4.0 g,the ratio of solid base is m(K2CO3): m(CH3COOK)=1:2;reaction time is 45 min.Under optimal conditions,the yield of cinnamic acid is 76%. |
