研究利用多种相转移催化剂在不同条件下通过糠醛的歧化反应制备糠醇和糠酸.结果表明:采用Span80为催化剂,当催化剂用量为质量分数5%、反应温度为15℃、反应3h时,糠酸的产率高达92%.
Furfural and furoic acid were prepared by disproportionation of furfural under different conditions using various phase transfer catalysts. The results showed that when using Span80 as catalyst, the yield of furoic acid was as high as 92% when the amount of catalyst was 5%, the reaction temperature was 15 ℃ and the reaction time was 3h.
