Abstract
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 formation of other products not previously found at oxidation of furan with hydrogen peroxide was detected. They included 2(5H)-furanone, 2,5-dihydroxy-2,5-dihydrofuran, and maleic dialdehyde. Small amounts of maleic and fumaric acids and also the product from polymerization of dihydroxydihydrofuran and dialdehyde were formed. The influence of the type of organic solvent, vanadium and phase-transfer catalysts, and the ratios of the reagents on the yield of the oxidation products were investigated. Authors: V. V.
