METODO PARA PRODUZIR UMA SOLUCAO OXIDANTE DE MISTURA DE PERACIDOS E METODOS DE TRATAR SUBSTRATOS COM AS REFERIDAS SOLUCOES

摘要

A process for treating a substrate, e.g., lignocellulosic pulp or cellulosic pulps with a mixed peracid solution comprising percarboxylic acid and Caro's acid which results in a higher conversion rate of the active oxygen in the hydrogen peroxide in order to provide an inexpensive and effective delignification and/or bleaching solution and the process for making the mixed peracid solution.
