<p>PROBLEM TO BE SOLVED: To obtain the subject solution by dissolving a specific cobalt Schiff base complex in an organic solvent, capable of making the complex be bonded to oxygen by adsorption of oxygen, precipitating the resultant substance as a solid and separating oxygen from an oxygen-containing gas such as air in high efficiency. SOLUTION: This complex solution for separating oxygen is obtained by dissolving a cobalt Schiff base complex of the formula [R1 is a (substituted) phenylene, a (substituted) pyridylene or a (substituted) alkylene; R2 to R5 are each H, a (substituted) phenyl, a (substituted) alkyl, a halogen or a (substituted) alkoxy; Me is methyl] in an organic solvent (e.g. o-dichlorobenzene) in 0.1-1mol/l concentration of the cobalt Schiff base complex, causes a phase separation due to the binding of the complex to oxygen resulting from adsorption of oxygen to cause precipitation as a solid phase and is capable of separating oxygen from an oxygen-containing gas such as air in high efficiency.</p> |
