METHOD FOR PRODUCTION OF POROUS INORGANIC FRAME BASED ON SILICON-CONTAINING COMPOUNDS WITH CONTROLLED RELEASE OF ACTIVE BIOCIDE (CHLORINE DIOXIDE) Russian patent published in 2022 - IPC A61L9/04

Abstract RU 2780481 C2

FIELD: chemistry.

SUBSTANCE: invention relates to means of air disinfection in premises. The use of silicon-organic bio-foam consisting of polymethyloctylsiloxane as a composition and tin octoate, hydroxysilane, tetraethoxysilane as a curing agent with further sorption and controlled desorption of chlorine dioxide is disclosed for air disinfection in public premises, in a volumetric ratio of composition : curing agent of 1:10.

EFFECT: invention is characterized by a constant speed of chlorine dioxide desorption, which provides its long-term desorption, its concentration in a radius of 1 m³, safe for the human respiratory tract, and protection from pathogenic bacteria and viruses.
