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. Amberlyst-15, a strongly acidic ion-exchange resin, functioned as an efficient solid acid catalyst for a highly selective SA production in the furfural oxidation ...
