MODIFIED CELLULOSE HAVING BIOCIDAL PROPERTIES AND PRODUCTION METHOD THEREOF Russian patent published in 2011 - IPC C08B15/06 

FIELD: chemistry.

SUBSTANCE: invention relates to biocidal fibrous materials based on cotton cellulose derivatives (2,3-dialdehyde cellulose of high degree of oxidation), modified with water-soluble ionogenic organic compounds, specifically quaternary ammonium cations of guanidinium methacrylate and synthesis method thereof. The invention describes modified cellulose having biocidal properties, based on dialdehyde cellulose and a biocidal substance containing amino groups, in which the biocidal substance used is guanidine methacrylate, and a method of producing modified cellulose, involving adding aqueous solution of an organic compound containing amino groups in ratio of dialdehyde cellulose to water equal to 1:30 (by weight) to dialdehyde cellulose, holding while stirring, filtering and drying, where the cellulose used has high degree of oxidation. 1.0-1.5% guanidine methacrylate solution is added and held at room temperature while stirring for 5-10 hours.

EFFECT: articles made from such material can be used to make clothes, packaging, dressing materials for medical purposes, as well as filter membranes for sterilising air and disinfecting river water, simultaneously having prolonged biocidal and easily regenerated adsorption properties since ionogenic groups are included in guanidine-containing compounds.
