| Abstract: | The characteristics of the oxidation of furfural in the hydrogen peroxide-VOSO4-sodium acetate system and the composition of the products were studied. The principal stages of the reaction occur at pH  7. The direction of the reaction is very different from the process in an acidic medium, where  -formylacrylic and maleic acids are mainly formed. The main oxidation products in the acetate buffer solution in the presence of VOSO4 are succinic and -formylpropionic acids and 2(5H)-furanone; without the catalyst the main product is 2-furancarboxylic acid. A mechanism is proposed for the transformations of furfural in the investigated system.For Communication 1, see [1].Kubansk State Technological University, Krasnodar 350072, Russia.
