METHOD OF PRODUCING STRUCTURED REGENERATIVE PRODUCT Russian patent published in 2016 - IPC A62D9/00 B01J20/04 B01D53/62 

FIELD: personal and household items; chemistry.

SUBSTANCE: invention relates to methods of producing structured products for air regeneration used in individual breathing apparatuses (IBA). Method of producing regenerative product involves mixing the solution of hydrogen peroxide stabilized by magnesium sulfate with potassium and sodium hydroxide, application of the obtained alkaline solution of hydrogen peroxide on a neutral porous matrix and subsequent dehydration of liquid phase on the matrix. After the addition of magnesium sulphate hydrogen peroxide solution is added with tetraborates of alkali metals, such as lithium, sodium, potassium tetraborates or their mixture are used, at the specified molar ratio of initial components. Regenerative product has high mechanical strength, provides high rate of the process of chemical absorption of carbon dioxide, prolonged protective effect during its operation in individual breathing apparatuses.

EFFECT: presence of alkali metals tetraborates in the alkaline solution of hydrogen peroxide and sequence of introduction of initial components into liquid phase makes it possible to reduce time of alkaline hydrogen peroxide solution preparation and to decrease release of atomic oxygen during the production cycle, id est to increase safety and cost effectiveness.
