The use of peroxide derivatives in chlorine-free bleaching of papermaking pulps
To intensify H2O2 as delignifier (and bleachant), peracetic acid was used at pH 7 or dimethyidioxirane was added as activator. Interstage activation (in 2-stage oxygen delignitication) with peracetic acid, dimethyidioxirane or (NH4)(2)MoO4-activated H2O2 (pH 5) increased delignification yield from 75 to 90%.
