Catalytic conversion of 5-hydroxymethylfurfural to some value-added derivatives

Abstract

The catalytic mechanisms and catalyst design strategies for 5-hydroxymethylfural conversion are summarized.

Heterostructured manganese catalysts for the selective oxidation of 5‐hydroxymethylfurfural to 2,5‐diformylfuran

“…This process entailed a tedious workup after the reaction for isolating the product from the homogeneous reaction mixture; thus less promising compared to the heterogeneous catalyst system, even though a high yield of DFF was achieved. Various precious metal oxides of Pt, Pd, Ru and Au on supported materials offered a high yield of DFF from HMF under aerobic oxidation conditions . For example, Ru/γ‐Al 2 O 3 afforded a near‐quantitative yield of DFF (97.3 %) in toluene at 130 °C, 2.7 bar O 2 .…”

Sustainable production of furfural and 5-hidroximetilfurfural from rice husks and soybean peel by using ionic liquid

“…From lignocellulosic biomass wastes, HMF can be obtained from cellulose, while furfural can be recovered from hemicelluloses (pentoses xylose and arabinose) (Rosatella et al, 2011;Zhang et al 2017). Both products are promising and typical platform chemicals that can be produced from the direct acid-catalyzed dehydration of biomass sugars (van Putten et al, 2013;Chen et al, 2017;Wang et al, 2017;Kong et al, 2018).…”

Highly efficient production of 2,5-dihydroxymethylfuran from biomass-derived 5-hydroxymethylfurfural over an amorphous and mesoporous zirconium phosphonate catalyst

“…Nowadays, growing interest and attention have been concentrated on the effective utilization of renewable lignocellulosic biomass to reduce the excessive dependent on non-renewable fossil resources [1] . 5-Hydroxymethylfurfural (HMF), which can be produced from various biomass-derived carbohydrates [2] , such as fructose, glucose, sucrose, inulin, starch and cellulose, is widely considered to be a very momentous platform compound and also recognized as one of "Top 10 + 4 bio-based chemicals by the United States Department of Energy [3] , this is because that it can be further converted into a series of high-value derivatives via various reactions [4] , such as oxidation, reduction, condensation, etherification, esterification, amination, decarbonylation and rearrange-ment. Among many possible derivatives, 2,5-dihydroxymethylfuran (DHMF), which is synthesized by the selective hydrogenation of HMF [5] , is particularly captivating due to its symmetrical structure and potential application in the preparation of ethers [6][7][8] , ketones [9][10][11] and polymers [12][13][14] , so it has already became a research hotspot in the academic field of biomass.…”
