Selective hydrogenation of aromatic furfurals into aliphatic tetrahydrofurfural derivatives

Abstract

<p>Tetrahydrofurfural (THFF) and 5-hydroxymethyltetrahydro-2-furaldehyde (5-HMTHFF) are important chemicals. Synthesis of THFF and 5-HMTHFF from the selective hydrogenation of furfural (FF) and 5-hydroxymethylfurfural (HMF) is highly desirable. However, it is a...</p>

Selective Hydrogenation of the Carbonyls in Furfural and 5-Hydroxymethylfurfural Catalyzed by PtNi Alloy Supported on SBA-15 in Aqueous Solution Under Mild Conditions

“…Moreover, hydrogen spillover is a phenomenon that the activated hydrogen atoms on the surface of active metal can migrate to the support ( Merte et al, 2012 ; Karim et al, 2017 ; Yang et al, 2020 ). From the result of WO 3 hydrogen spillover experiment as shown in Supplementary Figure S3 , the colour change of yellow-to-black for PtNi/SBA-15 confirmed the existence of hydrogen spillover.…”

“…The activated hydrogen atoms on SBA-15 support could also affect the selective hydrogenation of FF/HMF. It was found ( Yang et al, 2020 ) that hydrogen spillover significantly promoted the C=O hydrogenation when the support could adsorb the C=O groups. SBA-15 has been reported to efficiently adsorb carbonyl groups ( Huang et al, 2014 ).…”

“…Among the reported catalytic systems for FF/HMF hydrogenation and hydrogenolysis, monometallic catalysts (e.g., Pt, Pd, Ni, Cu) were widely employed and investigated ( Sitthisa and Resasco, 2011 ; Chen et al, 2016 ; Guo et al, 2016 ; Lima et al, 2017 ; Fan et al, 2020 ; Yang et al, 2020 ). For example, Fan et al (2020) reported that FF hydrogenation over 10 wt% Pt/C catalyst could yield 14% FFA with 71.2% selectivity at 413 K. Sitthisa and Resasco (2011) reported that 69% conversion of FF and 68% selectivity to FFA could be achieved on 10 wt% Cu/SiO 2 at 503 K .…”

Energy Densification of Biomass-Derived Furfurals to Furanic Biofuels by Catalytic Hydrogenation and Hydrodeoxygenation Reactions

“…The use of water as a solvent prevented the hydrogenation of the carbonyl group by inhibiting the adsorption of the carbonyl group on the metal surface. The synergism between water and the support (LDH-MgAl-NO 3 ) improved the selectivity of the product [105]. Polar solvents favored the hydrogenation of the furan ring rather than the carbonyl group of FUR [106].…”

Reductive Amination, Hydrogenation and Hydrodeoxygenation of 5‐Hydroxymethylfurfural using Silica‐supported Cobalt‐ Nanoparticles

“…The valorization of renewable resource, especially biomass and its based compounds to produce value-added chemicals and fuels as well as pharmaceutically relevant compounds in more efficient and sustainable manner continues to be an important goal of chemical research. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] In this regard the development of resourceful and cost-effective catalytic methodologies to convert biomass and its derived feedstock to essential products is of central importance. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Among sugar derived feedstocks, 5hydroxymethylfurfural (HMF) represents highly valuable platform compound, [20][21][22][23][24][25] which has been listed as the top 10 renewable chemicals by the U.S. Department of Energy.…”
