Catalytic Transfer Hydrogenation of Biomass-Derived 5-Hydroxymethylfurfural into 2,5-Dihydroxymethylfuran over Co/UiO-66-NH2

Progress in Selective Conversion of 5‐Hydroxymethylfurfural to DHMF and DMF

“…The reactions include hydrogenation, oxidation, biocatalysis, etherification, amination, condensation, electrolysis and halogenation etc. [66][67][68][69] HMF can prepare a wide range of compounds by catalytic hydrogenation to produce, for instance, the selective catalytic reactions of HMF produce 2, 5dimethylfuran (DMF), [70][71][72][73][74] 2, 5-dihydroxymethylfuran (DHMF), [75][76][77][78][79] 2, 5-dihydroxymethyltetrahydrofuran(DHMTHF), [80][81][82][83][84] 2, 5-dimethyltetrahydrofuran (DMTHF), [85][86][87][88][89] 5-methyfurfural (5-MF), [90][91] 2, 5-hexanedione (HD), [92][93][94] 1-hydroxyhexane-2, 5-dione (HHD), [95][96][97][98][99][100] 1, 2, 5hexanetriol (1, 2, 5-HT), [101] 1, 2, 6-hexanetriol (HTO), [102][103][104][105][106] 1, 6hexanediol (HDO), [107][108][109][110]…”

A Review on the Critical Role of H2 Donor in the Selective Hydrogenation of 5‐Hydroxymethylfurfural

“…From the poisoning experiment, the catalytic performance was obviously influenced by base sites rather than acid sites. High selectivity of DHMF up to 95.9 % was achieved with 92.6 % conversion of HMF under a mild reaction temperature (100 °C) [58] . Besides, MnO@C−N also had a high selectivity towards DHMF, and the highest yield of DHMF was 93 % at 170 °C, 21 h [59] …”

“…High selectivity of DHMF up to 95.9 % was achieved with 92.6 % conversion of HMF under a mild reaction temperature (100 °C). [58] Besides, MnO@CÀ N also had a high selectivity towards DHMF, and the highest yield of DHMF was 93 % at 170 °C, 21 h. [59] In summary, using isopropanol as the hydrogen donor is more convenient and safer with respect to its storage, transportation, and utilization in comparison with molecular hydrogen. Isopropanol possesses lower reduction potential as well as smaller steric hindrances, which are beneficial for lowering the reaction temperature and inhibiting the side reactions.…”

Chemo-catalytic synthesis of biomass-derived furanyl diethers: green and renewable bio-diesel components

“…Among the abovementioned three substrates, BHMF and HMF can be transformed towards furanyl diethers by etherication and reductive etherication, respectively, while the conversion of the cheapest fructose into furanyl diethers requires domino reactions including dehydration, hydrogenation and etherication as well as inevitable side reactions involved. 28,[53][54][55][56][57] Mechanistic pathways for these reactions were overviewed to provide insight into the development of green, cost-intensive and high-efficiency systems in the formation of furanyl diethers.…”
