Abstract
Pyromucic acid (PA) in aqueous solution is oxidized by molecular oxygen with opening of the furan ring and formation of Β-formylacrylic, fumaric, and formic acids. The process is accompanied by the interlinked oxidative decarboxylation of PA and the acids formed from it. PA is the major intermediate in the autooxidation of furfural. When PA and furfural are cooxidized, the rate of transformation of each compound increases by a factor of two; this is a sign of the interlinking of two radical processes evolving in one system. A probable scheme for the oxidation of PA in water by molecular oxygen is proposed.
