| Abstract: | With sodium cinnamate and benzyl chloride as raw material,tetrabutylammonium chloride as cata-lyst,benzyl cinnamate was synthesized directly under normal pressure and microwave irradiation.The effects of amount of catalyst,power and time of microwave irradiation on yield were studied.The most suitable reaction condi-tions were that with0.05mol sodium cinnamate,the mole ratio of sodium cinnamate and benzyl chloride was1.0:1.2,the amount of tetrabutylammonium chloride1.0g /0.05mol sodium cinnamate and the microwave irradiation time 25min with the power of300W.The yield of benzyl cinnamate was over84%. |
