Abstract

PURPOSE: To obtain a permeable membrane excellent in the selective permeability of oxygen, by using a cellulose derivative esterified by a specific aliphatic monocarboxylic acid as a selective permeable membrane for the separation of gases.
CONSTITUTION: A cellulose derivative is obtained by esterification of callulose with an aliphatic 5W16C monocarboxylic acid e.g., pentanoic acid, hexanoic acid, and the cellulose derivative thus obtained is used as a selective permeable membrane for the separation of gases, having an oxygen permeability of 10-9cc cm/cm2.sec.cmHg/ 25°C or more. The permeable membrane is widly used in the fields of combustion, medical treatment, etc., because of its great selective oxygen permeability.
