Abstract:
In this study, the conversion of monosaccharides to 5-hydroxymethylfurfural (5-HMF) using different deep eutectic solvents (DESs) was investigated in various conditions. Among all the investigated DESs, [ChCl][trichloroacetic acid], based on choline chloride and trichloroacetic acid with the ratio 1:1, showed the highest catalytic activity. A maximum 5-HMF yield was 82 % for 1 h at 100 °C using [ChCl][trichloroacetic acid] as a catalyst from fructose. [ChCl][trichloroacetic acid] could be recovered and reused three times with a slight loss in activity. Our work demonstrated the low-cost and effective method for the synthesis of 5-HMF from carbohydrates.
摘要:
在这项研究中,在各种条件下研究了使用不同的低共熔溶剂(DES)将单糖转化为5-羟甲基糠醛(5-HMF)。在所有被调查的DES中,[ChCl][三氯乙酸],以氯化胆碱和三氯乙酸的比例为1:1,显示出最高的催化活性。使用[ChCl][三氯乙酸]作为来自果糖的催化剂,在100°C下1小时的最大5-HMF产率为82%。[ChCl][三氯乙酸]可以回收并重复使用三次,活性略有损失。我们的工作证明了从碳水化合物合成5-HMF的低成本和有效的方法。
