摘要: 生物质平台分子5-羟甲基糠醛(5-HMF)的高附加值转化利用是当前的研究热点.使用溶胶凝胶法制备加氢醚化双功能Cu-Co催化剂,在温和条件下实现了5-HMF加氢醚化到2,5-二(甲氧基甲基)呋喃(BMMF).在130 ℃,2 MPa H2条件下反应2 h,得到最高85.9%的BMMF收率.双功能催化剂中Co3O4提供了路易斯酸酸性位点,同时还原得到的Cu2O及Co0提供了加氢氛围,最终实现了HMF一步加氢醚化制备BMMF.

Abstract: The conversion and utilization of biomass platform molecule 5-hydroxymethyl furfural (5-HMF) with high added value has always been a research hotspot. Bifunctional catalyst Cu-Co catalyst prepared by sol-gel method was used to catalyze the hydroetherification of 5-HMF to 2,5- bis (methoxy methyl) furan (BMMF) under mild conditions. The highest yield of BMMF is 85.9% at 130 ℃, 2 MPa H2 and 2 h. Co3O4 species in the bifunctional catalyst provide the Lewis acid site, while Cu2O and Co0 species provide the hydrogenation atmosphere, ultimately achieving one-step reduction etherification of HMF to BMMF.
