CrCl3催化果糖制备5-羟甲基糠醛的研究

CrCl3 Catalyzed Preparation of 5-Hydroxymethylfurfural from Fructose

摘要: 以CrCl3·6H2O为催化剂，考察溶剂种类、反应温度、反应时间、催化剂用量等条件对果糖制备5-羟甲基糠醛（HMF）产率的影响。结果表明，二甲基亚砜（DMSO）是果糖制备HMF的优良溶剂；以DMSO为溶剂，当反应温度为180 ℃、反应时间140min、 CrCl3·6H2O催化剂用量为果糖质量5%时，果糖制备HMF的产率可达49.2%。

Abstract: Taking CrCl3·6H2O as catalyst, the effect of the solvent type, reaction temperature, reaction time and the amount of catalyst on the yield of 5-hydroxymethylfurfural(HMF) from fructose was studied. The results showed that dimethyl sulfoxide (DMSO) was an ideal solvent to prepare HMF with fructose. The yield of HMF could be up to 49.2% under the conditions of using DMSO as the solvent, taking 5% of CrCl3·6H2O as catalyst based on the weight of fructose to react for 140min at 180℃.
