An investigation of the radical mechanism of the peroxidase oxidation of monomeric phenols (vanillin, vanillyl alcohol, isoeugenol, and α-quaiacylpropanone) has been made by the chemiluminescence method. It has been established that chemiluminescence is observed in those compounds that contain hydroxy or carbonyl groups on a carbon atom in the α position or have a C=C bond in the β position conjugated with the aromatic ring. The hypothesis has been put forward that peroxide compounds are inhibitors of autocatalytic processes in the oxidation of lignin in the presence of peroxidase.
