Oxidation of furan in system containing hydrogen peroxide, vanadium compound, chlorinated hydrocarbon, water, and phase-transfer catalyst was studied for the first time. In addition to the main product of this process - cis-β-formylacrylic acid - the form

Strategizing the exploitation of renewable solar light could undoubtedly provide new insight into the field of biomass valorization. Therefore, for the first time, we reported a heterogeneous photocatalytic oxidation route of renewable furfural (FUR) to produce industrial feedstocks maleic anhydride (MAN) and 5-hydroxy-2(5H)-furanone (HFO) under simulated solar light (AM 1.5G) using molecular oxygen (O2) as a terminal oxidant and mesoporous graphitic carbon nitride (SGCN) as a photocatalyst. SGCN showed an excellent photoconversion (>95%) of FUR with 42% and 33% selectivity to MAN and HFO, respectively. Moreover, an excellent selectivity towards MAN (66%) under natural sunlight indicates a pioneering route for the sustainable production of MAN. In addition, the underlying mechanistic route of the FUR photo-oxidation was investigated via various experiments including scavenger studies, substrate studies, and electron spin resonance (ESR) studies which constructively proved the pivotal role of singlet oxygen (1O2) and holes (h+) in FUR photo-oxidation.

The oxidation of 2-furaldehyde to β-formylacrylic acid in 0.1 N HClO4 containing hydrogen peroxide and sodium vanadate was studied by polarography using a dropping mercury electrode. The conversion of 2-furaldehyde and the yield of the products were found to depend on the reactant ratio. A mechanism was proposed which includes preliminary complex formation between the reactants.
