PREPARATION OF OXYGEN-ENRICHED AIR

PURPOSE:To prepare oxygen-enriched air by allowing an oxygen-concentrating medium comprising an asymmetric aromatic fluorocarbon to absorb air under a pressurized condition and subsequently forcing the oxygen-concentrating medium to release the air under a reduced pressure. CONSTITUTION:An oxygen-co...

Zusammenfassung:	PURPOSE:To prepare oxygen-enriched air by allowing an oxygen-concentrating medium comprising an asymmetric aromatic fluorocarbon to absorb air under a pressurized condition and subsequently forcing the oxygen-concentrating medium to release the air under a reduced pressure. CONSTITUTION:An oxygen-concentrating medium comprising an asymmetric aromatic fluorocarbon (e.g. oxygen-enriching perfluorocarbon 2) produced from only carbon atoms and fluorine atoms is allowed to absorb air under a pressurized condition (e.g. a pressurized absorbing tower 1) and subsequently to release the air under a reduced pressure condition. At least one of perfluorotoluene, perfluoro-1-methylnaphthalene and perfluoro-2-methylnaphthalene is employed as the asymmetric aromatic fluorocarbon.
