为了获得高效、绿色的糠醛（FF）生产反应体系，以γ-戊内酯（GVL）为溶剂，采用SO 3 H-封端的离子液体作为催化剂，研究了木糖转化反应。在140 ℃下，以1-丙基磺酸-3-甲基咪唑氯化物为催化剂，FF的产率可达78.42%。由于GVL的溶剂效应，GVL能提高酸性质子的催化活性，抑制副反应，显著提高反应速率，提高木糖转化率和FF收率。此外，由于通过引入SO 3 H基团进行功能化，离子液体在木糖转化为FF中显示出令人满意的催化性能。在该系统中还测试了其它CS碳水化合物（阿拉伯糖和木聚糖）的转化，并且实现了中等的FF产率。
To obtain an efficient and green reaction system for the production of furfural (FF), this study investigated the use of a SO3H-finactiopgized ionic liquid as a catalyst for the conversion of xylose in a solvent of renewable gamma-valerolactone (GVL). A high FF yield of 7842% was obtained in this reaction system catalyzed by 1-propylsulfonic-3-methylimidazolium chloride at 140 degrees C. The GVL remarkably enhanced the reaction rate and increased the xylose conversion and FF yield because the solvent effect of GVL, could improve the catalytic activity of the acidic protons and suppress the side reactions. In addition, the ionic liquids showed satisfactory catalytic performance in the conversion of xylose to FF due to functionalization by introducing a SO3H group. The conversion of, other CS carbohydrates (arabinose and xylan) was also tested in this system, and moderate FF yields were achieved.
