摘要：

The kinetics of interaction of hydrogen peroxide (H2O2) with lignosulfonic acid (LSA) and nitrolignin (NL) have been studied as well as with LSA methylated with diazomethane or methyl-sulfate. Changes in the functional composition of LSA and in its infrared spectra as a result of oxidation by hydrogen peroxide were investigated. It was established that hydrogen peroxide consumption proceeds by two radical chain routes and by a non-radical mechanism under interaction with water-soluble mathematical model of kinetics of H2O2 interaction with lignin derivatives was obtained by an analysis of the kinetic scheme. The model is consistent with kinetic results for the oxidation of LSA and nitrolignin by peroxide. Copyright (C) 1996 Published by Elsevier Science Ltd.
