Abstract:
Green oxidation of 2-furaldehyde (furfural) and its homologues were investigated using solid acid catalyst and hydrogen peroxide (H₂O₂) in aqueous media to form succinic acid (SA), a key chemical that affords wide applications in macromolecular, pharmaceutical and agrochemical industries. Amberlyst15, a strongly acidic ion-exchange resin, functioned as an efficient solid acid catalyst for a highly selective SA production in the furfural oxidation reaction. The synthesized SA was simply isolated in high purity (supported by NMR spectral data). Furthermore, the utilization of Amberlyst-15 with H₂O₂ was also useful in oxidizing carbonyl derivatives of furan (furfural, 5-hydroxymethyl-2-furaldehyde, furoic acid) to a one carbon less linear di-carboxylic acid such as SA and 2-oxoglutaric acid (OGA) under moderate conditions. This catalytic oxidation process with an acid catalyst and H₂O₂ promises to be a viable route for SA syntheses since they have the advantages of easy handling and simple purification decreasing the cost for the production, as compared to the current state of art.
