摘要:

开发了以离子液体1-丁基-3-甲基咪唑氯盐([BMIM]Cl)为溶剂, 固体酸离子交换树脂NKC-9为催化剂转化果糖为5-羟甲基糠醛的绿色工艺. 在此催化体系中, 100 ℃下反应10 min时5-HMF的产率达到78.0%, 其反应时间远远小于已有文献报道的长达数小时的反应时间. 在此催化体系中, 果糖起始浓度的增加对5-HMF产率影响不大, 因而此工艺同样适用于处理高浓度的果糖溶液. 离子液体[BMIM]Cl和树脂组成的催化体系可以循环使用, 经过9次重复使用后仍能保持稳定的催化活性.

Abstract:

An efficient process for the dehydration of fructose to 5-hydroxymethylfurfural(5-HMF) in ionic liquid 1-butyl-3-methyl-imidazolium chloride([BMIM]Cl) in the presence of ion-exchange resin was deve-loped. A 5-HMF yield of 78.0% was achieved in 10 min at 100 ℃, where the reaction time required was much lower than that reported in previous works for converting fructose to 5-HMF. No remarkably decrease in 5-HMF yield occurred for initial fructose concentrations up to 20%(mass fraction). The ionic liquid and ion-exchange resin could be recycled and exhibited constant activity for 9 successive trials.
