| 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140 min、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 140 min at 180℃. |
