Features of the initial stages of the oxidation of lignin by hydrogen peroxide
The kinetics of the initial stages of the oxidation of lignin and of several model compounds have been studied by the stopped-jet method. It has been shown that in the initial stage an intermediate compound is formed with an absorption spectrum close to that of phenoxyl radicals and with a lifetime of 0.013 sec. The high reactivity of the intermediate products leads to a branching of the oxidation process.
