Abstract The conversion of hemicellulose-derived xylose to furfuryl alcohol is a practical procedure for producing value-added chemicals from biomass. In this study, a bifunctional Cu/SBA-15-SO3H catalyst was employed for the one-pot catalytic conversion of xylose to furfuryl alcohol with a yield of up to 62.6% at the optimized conditions of 140 °C, 4 MPa, and for 6 h in a biphasic water/n-butanol solvent. A high reaction temperature resulted in further hydrogenation to 2-methyl furan, while a high hydrogen pressure led to a side hydrogenation reaction to xylitol. The biphasic solvent allowed xylose solvation as well as furfuryl product extraction. The acidic –SO3H sites and Cu sites co-existed, maintained a balance, and cooperatively catalyzed the cascade conversion. Excessive acidic sites and large pores could promote the xylose conversion, although a low furfuryl alcohol yield was obtained. This catalytic system could be potentially applied to the one-pot synthesis of furfuryl alcohol from hemicellulose-derived xylose.

双功能Cu/SBA-15-SO3H催化剂上木糖一锅级联转化为糠醇

摘要 将半纤维素衍生的木糖转化为糠醇是从生物质生产增值化学品的实用程序。在本研究中，采用双功能 Cu/SBA-15-SO3H 催化剂在 140 °C、4 MPa 的优化条件下将木糖一锅法催化转化为糠醇，产率高达 62.6%。在双相水/正丁醇溶剂中 6 小时。高反应温度导致进一步氢化成 2-甲基呋喃，而高氢气压力导致副氢化反应生成木糖醇。双相溶剂允许木糖溶剂化以及糠基产物提取。酸性–SO3H 位点和Cu 位点共存，保持平衡，协同催化级联转化。过多的酸性位点和大孔会促进木糖转化，虽然得到低糠醇收率。该催化系统有可能应用于从半纤维素衍生的木糖中一锅法合成糠醇。
