INCREASING REACTION CAPACITY OF CELLULOSE MASS Russian patent published in 2011 - IPC C08B1/08 D21C9/00 C08B9/00

Abstract RU 2434020 C2

FIELD: chemistry.

SUBSTANCE: method of obtaining alkaline cellulose involves a step for providing a cellulose mass, which contains cellulose fibres with free space between fibres, and treating said cellulose mass with an alkali to obtain alkaline cellulose. Alkaline treatment takes place in the presence of an expander which is capable of penetrating the space between cellulose fibres. The expander is a hydrophilic polymer which can be dissolved or dispersed in aqueous solution.

EFFECT: high reaction capacity of cellulose mass.
