| Abstract: | α-furanacrylic acid was synthesized by perkin reaction of furfural and acetic anhydride, and factors influencing the yield were studied. It was found that when n （furfural）：n （anhydrous potassiuim carbonate） ：n（acetic anhydride）=1：0.56：2.33, and anhydrous potassium carbonate was as catalyst, the reaction was carried out for 30 min at 150 ℃, the yield of α-furanacrylie acid was kept about 68.00 %. And α-furanacrylic acid was determined by FT-IR . |
