摘要： Alkaline solutions of hydrogen peroxide or compounds capable of providing peroxide ions are used to bleach cellulose and other fibrous materials in the manufacture of paper. Owing to the transition-metal ions contained at low concentrations in the cellulose fibres, the peroxides undergo homolytic decomposition, thus leading to considerable losses of peroxide and, owing to the reactivity of the oxygen radicals formed, cleavage of the carbohydrate chains. To stabilize such bleach liquors, the method proposed uses, alone or in the form of a mixture, a combination of a type 1 complexing agent consisting of a phosphonate and/or poly- alpha -hydroxyacrylic acid and/or an aminopolycarboxylic acid and a type 2 complexing agent consisting of oxy and/or polyoxy compounds with 2 to 7 C-atoms in the carbon chain and/or protein derivatives. This stabilizer is suitable for use in stabilizing alkaline bleaching solution containing oxygen, hydrogen peroxide and/or compounds capable of providing peroxide ions and can be used, under oxygen pressure, under ambient pressure or under hydrostatic pressure, to bleach aqueous fibre suspensions in the manufacture of paper or in the processing of fibrous materials (synthetic fibres) used in the chemical industry. The stabilizer mixture gives an excellent degree of bleaching, at the same time enabling hydrogen peroxide consumption to be significantly reduced, the fibres are damaged much less by the bleach and the stabilizer mixture is more readily biodegradable than type 1 complexing agents.
