Acid prehydrolysis does not impede subsequent peroxide delignification, increases the mass fraction of α-cellulose, and improves the reactivity of cellulose but does not ensure a high degree of modification. Aqueous prehydrolysis is less effective. Cold alkaline modification of coniferous (spruce) prehydrolysis peroxide cellulose is highly effective and increases the mass fraction of α-cellulose to 97.5%. Deciduous wood is delignified and modified more easily than coniferous wood. Deciduous (birch) cellulose with up to 99% mass fraction of α-cellulose can be obtained by peroxide cooking with acid prehydrolysis, finishing, and cold alkaline modification. The process regimes developed allow processing highly modified coniferous and deciduous cellulose with properties as good as sulfate cord cellulose with minimal technogenic environmental pollution.

An environmentally clean peroxide method of manufacturing cellulose was developed as an alternative to the traditional pulping method. Spruce and birch are delignified with hydrogen peroxide in acid medium in the presence of catalysts and the cellulose undergoes bleaching and cold alkali modification. The properties of the cellulose obtained are as good as sulfate cord cellulose.

The possibility of fabricating cotton cellulose from linters with a process scheme which provides for altering the order of the stages of alkaline and acid cooking was investigated. The molecular and process indexes of the cellulose obtained were determined. The possibility of fabricating cotton cellulose with a satisfactory content of α-cellulose, degree of polymerization, and reactivity was demonstrated.
