摘要

5-羟甲基糠醛是一种具有很高利用价值的化学平台化合物。以离子液体1-丁基-3-甲基咪唑氯盐（[Bmim]Cl）为溶剂，以CrCl3和AlCl3为复合催化剂，在油浴加热条件下催化纤维素降解制取5-羟甲基糠醛，研究了催化剂种类、催化剂量、温度、纤维素浓度、气氛、纤维素聚合度、反应规模等不同因素对纤维素降解制取5-羟甲基糠醛的影响。结果表明，[Bmim]Cl用量为10 g，棉花添加量为0.5 g，x（CrCl3）=25%（mol），x（AlCl3）=2.5%（mol），反应温度为120℃，反应气氛为N2（dry）气氛，反应时间为4 h时，HMF产率最高，达到59%。此外，反应过程中水的作用机理也被给予了相应解释。

Abstract

5-Hydroxymehylfurfural (HMF)

as a valuable platform chemical compound

can be obtained by the direct catalytic conversion of cellulose. The composite catalyst of CrCl3 and AlCl3 was used to convert cellulose into HMF in 1-butyl-3-methyl imidazole chloride ([Bmim]Cl) under oil-bath heating. The effect of catalyst dosage

temperature

cellulose amount

atmosphere

polymerization degree and reaction scale were investigated. The highest HMF yield of 59% was obtained at 4 h when 0.5 g cotton was added into[Bmim]Cl with 25%-2.5% dosage of CrCl3-AlCl3 at 120℃ under N2 (dry) atmosphere. The production efficiency was improved while the cost was reduced. Additionally

the mechanism of degradation of cellulose was proposed.
