| 摘 要： | 果糖脱水降解为5-羟甲基糠醛是生物质资源综合利用的研究热点。以AlCl3为催化剂，考察反应条件对果糖脱水制备5-羟甲基糠醛的影响，重点研究不同无机酸对AlCl3催化果糖降解生成5-羟甲基糠醛反应的影响。以AlCl3和无机酸为共催化剂，考察在不同溶剂（1,4-二氧六环、N,N-二甲基甲酰胺、2-甲基亚砜）、反应温度和硫酸与磷酸质量比（1∶2、2∶3、3∶2、2∶1）条件下对果糖脱水降解制5-羟甲基糠醛的影响。结果表明，以温和的N,N-二甲基甲酰胺为溶剂，在反应温度120 ℃、AlCl3用量为7.5 mmol、硫酸为20 mmol·L-1和磷酸为30 mmol·L-1共催化剂条件下，5-羟甲基糠醛收率达92.1%。

| Abstract: | Abstract： The dehydration of fructose to 5-hydroxymethylfurfural is the research hotspot of the comprehensive utilization of biomass resources. Using AlCl3 as the catalyst, the influence of reaction conditions on the dehydration of fructose to 5-hydroxymethylfurfural, especially the addition of different inorganic acids on the catalytic performance of AlCl3 was investigated. Using inorganic acid and AlCl3 as the co-catalyst, the effects of different solvents （ 1,4-dioxane, N, N-dimethylformamide, 2-dimethyl sulfoxide ）, reaction temperature and the mass ratio of sulphuric acid to phosphoric acid （ 1： 2,2： 3,3： 2,2：1 ） were tested. The results showed that 5-hydroxymethylfurfural yield of 92.1% was attained under the condition as follows ： N,N-dimethylformamide as the solvent,AlCl3 dosage 7.5 mmol, sulphuric acid concentration 20 mmol ·L^-1, phosphoric acid concentration 30 mmol·L^-1 and reaction temperature 120 ℃ |
