Kinetics of reaction of chlorine dioxide with residual lignin of hardwood sulphate pulp

The kinetic parameters of the reaction of chlorine dioxide with residual lignin pulps after industrial processing - ClO 2 flow rate constants in aqueous suspension of sulphate cellulose on reactions of the first and second order - are defined. It is established that with delignification of hardwood kraft pulp lignin the reactivity of residual lignin against ClO 2 decreases.
