高くなるという欠点を有している。"Prior Art" Industrial production of oxygen has been carried out since the beginning of this century by cryogenic separation. This method is considered to be the most suitable method when producing large quantities of oxygen using large-scale equipment, but it requires an extremely large amount of energy;
Furthermore, in the case of on-site use, it is necessary to first fill the container in a pressure-resistant container and transport it, which results in a significant increase in cost. In addition, as a method for producing oxygen on a relatively small to medium scale, a method has recently appeared that uses zeolite molecular sieves, carbon, and other adsorbents to separate oxygen from air in high concentrations by utilizing the difference in the amount of nitrogen and oxygen adsorbed on adsorbents. In particular, it is used for various wastewater treatment, injection into various furnaces, medical purposes, etc. However, it has the drawback that the power consumption required to produce oxygen is high, which increases the cost of producing oxygen. are doing.

られる。"Function" A cobalt dihistidine complex is obtained by reacting histidine with a cobalt salt. Histidine is L-form,
Either the DL form or the D form may be used. In addition, cobalt salts include cobalt oxide, hydroxide chloride, monochloride, and its hydrates, inorganic acids and organic acids, monochloride salts and hydrates, double salts, and organic polyester compounds. However, divalent inorganic salts are particularly preferably used.

液を長期に保持することから、好ましく用いられる。By using an organic solvent, separation performance is significantly improved compared to when water is used as a solvent. Among organic solvents, polyhydric alcohols such as ethylene glycol and glycerin are particularly preferably used because they dissolve the complex well, have a slow evaporation rate, and maintain the complex solution for a long period of time.

ｍの範囲にあるものがよい。In addition, these polyhydric alcohols include methanol, ethanol,
Mixing a lower alcohol such as isopropyl alcohol is also useful because it lowers the viscosity of the complex solution and increases the diffusibility of the complex. If the concentration of the complex in the complex solution is low, the effect of facilitated transport will not appear. If the concentration is too high, the diffusion of the complex will be suppressed, especially from 0.1 to 0.6 mol/l.
The material of the support that holds this complex solution is not particularly limited, but examples include fluororesins such as polyvinylidene fluoride and polytetrafluoroethylene, polyolefin resins such as polyethylene and polypropylene, and other organic polymer materials. It will be done. These supports may be non-porous or porous, or a composite thereof, but porous membranes are preferably used from the viewpoint of retention of the complex solution and oxygen permeability. Further, the shape of the deaf can be either a flat membrane shape or a hollow fiber shape. In the case of a porous membrane, the pore size is not particularly limited, but is preferably 0.01 to 10 μm from the viewpoint of complex retention.
It is preferable to use one within the m range.
これら支持体に錯体溶液を流延あるいは含浸させること

ことが錯体溶液の分離性能を発現させる上で必要である
。このため真空含浸や加圧操作が有効である。These supports are held by casting or impregnating them with a complex solution. In particular, when a porous support is impregnated with a complex solution, it is necessary to impregnate the porous support homogeneously without leaving any air bubbles in order to achieve separation performance of the complex solution. For this reason, vacuum impregnation and pressurization operations are effective.
