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%。

关 键 词:果糖  5-羟甲基糠醛  氯化铬  催化

Abstract:Taking CrCl3·6H20 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 CrCl3·6H20 as catalyst based on the weight of fructose to react for 140 min at 180℃.
Keywords:fructose  5 - hydroxymethylfurfural(HMF)  Chromic Chloride( CrC13 )  catalysis
