<p>PURPOSE:To obtain the title material for selectively separating gases having a high oxygen adsorption and desorption rate and capable of efficiently concentrating oxygen by mixing a Co salt, an amine compd. having a skeleton shown by a specified formula, and org. acids. CONSTITUTION:(A) A Co salt (e.g., cobalt thiocyanate), (B) an amine compd. (e.g., tripropylenetetramine and a compd. shown by formula II) having a skeleton shown by formula I [(n) is 2-10<5> or preferably 2-1,000] and (C) org. acids (e.g., 2-furancarboxylic acid silicifluoride) are mixed to obtain the material for selectively separating gases. Since the separation performance of the separation material is high even when the material is used as the permselective membrane for gases or as the material for selectively separating gases, oxygen can be highly concentrated. Since the oxygen adsorption and desorption rate of the material is high, oxygen can be concentrated extremely efficiently.</p> |
