Optimization Synthesis of cinnamic acid

Objective To optimize the synthesis of cinnamic acid Comparison of different catalysts,reaction temperature and reaction time on the synthesis of cinnamic acid.Methods Target compound was synthesized by means of the Perkin, and the influence of temperature,catalyst,reaction timeon the yield was investigated.Results The best result was obtained at 160℃with a reaction time of 50min,and the catalyst is K_2CO_3,cinnamic acid production was higher,yield 80.5%. Conclusions The best process improved the synthesis yield,can be easily operated with cheap reactants and high yield. Then the experimental method is suitable for production.
