本文研究了用无水碳酸钾和无水氟化钾催化的糠醛与乙酸酐的Perkin反应,探索了其较佳的反应条件。当用无水碳酸钾作催化剂时,呋喃丙烯酸的产率为62%;若用无水氟化钾作摧化剂,则呋喃丙烯酸的产率可达到82.6%。
In this paper, Perkin reaction of furfural with acetic anhydride catalyzed by anhydrous potassium carbonate and anhydrous potassium fluoride was studied, and the better reaction conditions were explored. The yield of furan acrylic acid was 62% when anhydrous potassium carbonate was used as a catalyst. The yield of furan acrylic acid could reach 82.6% if anhydrous potassium fluoride was used as a catalyst.
