摘　　要：在微波辐射和相转移催化剂的条件下,利用Perkin反应,快速合成了α 呋喃丙烯酸;考察了微波辐射功率、微波辐射时间、不同种类的相转移催化剂、催化剂用量及反应物的物料比对反应产物的影响.研究结果表明:在微波辐射功率为260W、微波反应时间为11min、以聚乙二醇1000(PEG1000)为相转移催化剂,糠醛与乙酐的体积比为1∶2,糠醛与无水碳酸钾的量比为1.00∶0.55时,α 呋喃丙烯酸的产率为72.3%.The phase transfer catalytic (PTC) synthesis of furanacrylic acid under microwave irradiation was reported. The experiment results show that the best reaction conditions are as follows. The volume ratio of furaldehyde to acetic anhydride is 1∶2; the mole ratio of furaldehyde with anhydrous potassium carbonate is 1.00∶0.54. The best phase transfer catalyst is PEG1000, the mass ratio of PEG1000 with furaldehyde is 4.3%, the reaction time is 11 min, the reaction power of microwave is 260 W. The yield of αfuranacrylicacid is up to 72.3% under these reaction conditions.
