Selective production of succinic acid from furfural with H2O2 over Sn-Beta, a pure Lewis catalyst, is reported. Under optimized reaction conditions, 53% yield was obtained, and the catalyst recyclable. 2(3H)-Furanone detected as an intermediate using 1H nuclear magnetic resonance (NMR), HH correlation NMR spectroscopy, liquid chromatography–mass spectrometry (MS) gas chromatography–MS. Kinetic modeling revealed that Baeyer–Villiger oxidation to 2(3H)-furanone accelerated in comparison other...
Industrial chemicals with a four-carbon structure, including maleic acid, 1,4-butanediol, γ-butyrolactone, and pyrrolidones, are derived from petroleum. Catalytic synthesis of these C4 biomass is challenging because the scarcity sugars in feedstock. We show that 5-hydroxy-2(5H)-furanone (5H5F), produced by catalytic oxidation biomass-derived furfural, versatile platform for several oxygen- nitrogen-containing chemicals. In our study, 5H5F was synthesized 92% yield room-temperature furfural...
Hydrogenation of carboxylic acids to lactones is an important reaction. However, strong adsorption acid on the catalyst causes poisoning active site and demands harsher reaction condition organic solvents. In this study, we demonstrate that metal support interaction (SMSI) hydrogen spillover Ru/V2O3 can counter such effect. The with SMSI was able hydrogenate succinic γ‐butyrolactone (GBL) in 77% yield presence water at mild conditions 150 °C. H2‐D2 exchange experiment showed for catalysts...
Abstract Chemicals with a four‐carbon chain (C4 chemicals), like succinic acid, maleic 1,4‐butanediol, and tetrahydrofuran are extensively used as commodity chemicals polymer precursors. Currently, these commercially synthesized from petrochemical based feedstocks. There is growing interest in catalytic pathways for producing other C4 biomass. However, biomass mainly composed of hexose pentose sugars the natural abundance feedstock low. This review summarizes current development chemical...
Hydrogenation of carboxylic acids to lactones and alcohols is an important reaction. However, strong adsorption acid on the catalyst surface leads poisoning active site, demands harsher reaction condition use organic solvents. In this study, we demonstrate that metal support interaction (SMSI) hydrogen spillover Ru/V2O3 can counter effect. The catalysts reduced at 400 C formed a layer V2O3 over Ru. was able hydrogenate succinic gamma-butyrolactone (GBL) in 77 % yield presence water mild...
Industrial chemicals with a four-carbon backbone like maleic acid, 1,4-butanediol, gamma-butyrolactone and pyrrolidones are currently obtained from petroleum. Synthesis of these C4 biomass is difficult owing to the low abundance sugars development suitable platform chemical necessary. We show that 5-hydroxy-2(5H)-furanone (5H5F) versatile for above mentioned chemicals. 5H5F was synthesized by oxidation furfural at room temperature in presence TS-1 catalyst 92 % yield isolated extraction. As...
