ABSTRACT A process for the production of a carbon dioxide absorbing material based on calcium hydroxide is disclosed. The process comprises precipitating calcium hydroxide from an aqueous solution of a calcium salt with an alkali hydroxide. The pre- cipitated product is filtered off, washed with water, dried and granulated. The material produced in this process has a very high and reproducible ability of binding carbon dioxide and can be advantageously used in breathing apparatuses.
