| 摘 要： | 考察了杂多酸及其盐对果糖脱水制备HMF的催化性能。研究表明,磷钨酸铯盐催化效果较好,高温反应对5-羟甲基糠醛(HMF)生成有利,添加助剂聚乙烯吡咯烷酮(PVP)可提高产率。通过对反应温度、催化剂、加料方式的考察,得出优化的反应条件为:将果糖溶于DMSO中,添加质量分数20%的PVP,升温至155℃加入占果糖摩尔分数1%的CsH2PW12O40,反应5 min,产率77.9%。

| Abstract: | The derivatives of 5-hydroxymethylfurfural are important materials for the synthesis of biodegradable polymers. It can be formed by the dehydration of D-fructose in the presence of acid catalyst. The activity of heteropoly acid and its salts was investigated. In addition, the effect of the temperature, addition of PVP, and the charging method were studied. The results showed that elevated temperature favor high yield and the Cs salt of Phosphotungstic acid, especially CsH2PW12O40, gave good results. HMF was obtained in 77.9% yield while using 1 mol% CsH2PW12O40 as catalyst, 20 wt% PVP as addictive, and react at 155 oC for 5 min. |
