Selective hydrogenolysis of 2-furancarboxylic acid to 5-hydroxyvaleric acid derivatives over supported platinum catalysts

Abstract

Pt catalysts, especially supported on Al2O3, are effective for hydrogenolysis of 2-furancarboxylic acid to 5-hydroxyvaleric acid (5-HVA) and its derivatives (ester and δ-valerolactone), and the highest yield of 5-HVA derivatives was 62%.

Liquid Phase Furfural Oxidation under Uncontrolled pH in Batch and Flow Conditions: The Role of In Situ Formed Base

“…In the domain of resins, new routes for producing 5-hydroxyvaleric (esters forms [5]), agrochemical, flavour and fragrance industries. In the domain of resins, new routes for producing 5-hydroxyvaleric acid from furoic acid can also be highlighted [6]. However, other products can also be obtained from furfural oxidation, such as maleic acid, succinic acid, 2(5H)furanone and CO2 [4,7].…”

Scalable synthesis and polymerisation of a β-angelica lactone derived monomer

“…1 H NMR (400 MHz, CD 2 Cl 2 , signals of β-isomer are reported) δ 7.46 (dd, J = 5.7, 1.5 Hz, 1H), 6.04 (dd, J = 5.7, 2.0 Hz, 1H), 5.11 (qt, J = 6.9, 2.0, 1.5 Hz, 1H), 1.41 (d, J = 6.9 Hz, 3H). 13…”

“…1 Platform chemicals are small molecules that can be produced in good yields from bio-based raw materials such as lignocellulose or sugars by fermentation or by using thermocatalytic reactions. 2,3 Further ( preferably catalytic) conversions of these chemicals allows the synthesis of fine chemicals, [4][5][6][7][8] monomers, [8][9][10][11][12][13] and fuels. 14,15 Especially renewable polymers [16][17][18] and adhesives 19 based on them, often have novel properties which are considered an advantage beyond renewability.…”

Biomass valorisation over metal-based solid catalysts from nanoparticles to single atoms

“…Very recently, the selective hydrogenolysis of 2-furan carboxylic acid (FCA) to a high value aliphatic compound bearing two terminal oxygen-containing functional groups, 5-hydroxyvaleric acid (5-HVA), was demonstrated on Pt/SiO 2 and Pt/Al 2 O 3 . 19,20 The Pt/SiO 2 catalyst was able to suppress the cleavage of d-C-O bonds and the hydrogenation of the furan ring at low temperature (40 1C) and 30 bar H 2 in water. 19 The TOR of FCA conversion and the cleavage of a-C-O bonds towards selective 5-HVA synthesis were tuned by controlling the platinum particle size.…”

“…Pt/Al 2 O 3 also selectively transformed FCA into 5-HVA derivatives at 100 1C and 40 bar H 2 in methanol. 20 5-HVA derivatives were associated with a total selectivity of 62%, with methyl 5-hydroxyvalerate making up 55% of them. By-products formed through ring hydrogenation (i.e., THFCA and its methyl ester hydrogenolysis (i.e., valeric acid, VA).…”
