摘要
针对5-羟甲基糠醛传统制备方法存在的问题,采用离子液体1-丁基-3-甲基咪唑氯盐为溶剂、1-氢-3-甲基咪唑氯盐为催化剂。在不同实验条件下,系统研究了纤维素绿色转化制备5-羟甲基糠醛的反应过程。结果表明,该方法可以实现纤维素的均相转化,具有较高的反应效率,反应过程更加绿色安全。通过对反应温度、催化剂浓度和反应时间的考察,获得了最佳的反应条件。
In view of the problems rooted in the traditional methods of 5-hydroxymethylfurfural preparation,ionic liquids 1-butyl-3-methylimidazolium chloride and 1-hydrogen-3-methylimidazolium chloride were used as solvent and catalyst,respectively. On this basis,systematic study on the green conversion of cellulose into 5-hydroxymethylfurfural was carried out in this work. Experimental results showed that conversion of cellulose was achieved with higher yield by this method. The reaction process was safer and more environmentally-friendly. According to the investigation on experimental temperature,reaction time and molar concentration of catalyst,the optimal experimental conditions were obtained.
