Abstract: | The oxidation of furfural by an aqueous solution of hydrogen peroxide in the presence of sodium molybdate was studied for the first time. Its final products are 2(5H)-furanone and also tartaric, malic, and succinic acids. The process takes place through the formation of peroxide and carbonyl compounds. Kinetic curves for the consumption of the reagents and the accumulation of the reaction products were obtained. In direction oxidation in this system differs substantially from the previously studied reactions of furfural with an aqueous solution of hydrogen peroxide without a catalyst and in the presence of selenium and vanadium compounds.For Communication 3, see 1].Kubansk State Technological University, Krasnodar 350072, Russia.
