METHOD FOR PRODUCTION OF CALCIUM PEROXIDE Russian patent published in 2006 - IPC C01B15/43 B01J20/04

Abstract SU 1839945 A1

FIELD: inorganic chemistry, in particular production of sorbent for individual breathing apparatus.

SUBSTANCE: Calcium chloride hexahydrate is dissolved in concentrated ammonia solution under cooling to 15-17°C, wherein molar ratio of CaCl₂.6H₂O:NH₃ = 1:1. Concentrated hydrogen peroxide solution is added to obtained solution in four-multiple excess. Formed precipitate is filtered, washed and dried. Obtained calcium peroxide gas specific surface of 92-96 m /g, dynamic activity based on carbon dioxide at temperature of 300-400°C is 80 l/kg.

EFFECT: sorbent for individual breathing apparatus of improved quality.
