摘　　要：以苄基三乙基氯化铵为相转移催化剂,K2CO3为催化剂,通过Pinker反应合成了肉桂酸。在回流条件下,以苄基三乙基氯化铵为相转移催化剂时,n(苯甲醛)∶n(乙酸酐)∶n(碳酸钾)∶n(苄基三乙基氯化铵)=1∶3∶1∶0.03,回流90min,肉桂酸的产率可达到78.5%。Synthesis of cinnamic acid via Pinker reaction catalyzed by potassium carbonate under phase trans-fer catalysts benzyltriethylammonium chloride was studied. The optimum conditions for the reaction in the presence of phase transfer catalyst benzyltriethylammonium chloride were as follows： the molar ratio of benzaldehyde to acetic anhydride to potassium carbonate to benzyltriethylammonium chloride was 1 ∶3∶1∶0.03; the reaction time was90 min under reflux; the yield of cinnamic acid could reach 78.5%.
