| 摘 要： | 在离子液体中采用不同的Lewis酸催化葡萄糖和果糖脱水制备5-羟甲基呋喃甲醛(5-HMF).结果表明,CrCln和SnCln均可高效催化葡萄糖转化为5-HMF.另外,Lewis酸的酸性越强,其催化果糖转化为5-HMF的产率越高.镧系金属氯化物在反应中表现出较好的催化活性和产物选择性.同时还研究了离子液体结构对催化反应的...

| Abstract: | A variety of Lewis acids have been examined for the transformation of glucose and fructose into 5-hydroxymethylfurfural (5-HMF) in ionic liquids (ILs).SnCln and CrCln are effective catalysts for the isomerization,and Lewis acids with strong acidity can facilitate the dehydration of fructose.The influence of ILs' structure,including the length of alkyl side chain and halide anions,on the conversion was also studied.A distinct odd-even carbon-atom-number effect is observed in the conversion of glucose to 5-HM... |
