GAS SELECTIVE SEPARATING MATERIAL

PURPOSE:To efficiently recover CO or the like, by mixing copper compd. with ascorbic acids in a solvent and using the mixture as an absorbent and a separating material of gas such as a permeable membrane. CONSTITUTION:Copper compd. such as Cu(NO3)2, Cu(CH3CO2)2, CuF2, CuI2 and Cu(BF4)2 is mixed with...

Zusammenfassung:	PURPOSE:To efficiently recover CO or the like, by mixing copper compd. with ascorbic acids in a solvent and using the mixture as an absorbent and a separating material of gas such as a permeable membrane. CONSTITUTION:Copper compd. such as Cu(NO3)2, Cu(CH3CO2)2, CuF2, CuI2 and Cu(BF4)2 is mixed with ascorbic acids such as L-ascorbic acid in the solvent incorporating N-contg. heterocyclic compd. such as N-methylimidazole. This mixture is used as the absorbent or a gas permeable membrane held with it on a supporting membrane and thereby CO is recovered with high yield from CO-contg. gas by selectively absorbing CO or selectively permeating CO.
