(1) Synthesis and Evaluation of Oxygen Ccrrier : Among Cobalt-based carriers for oxygen, Co (salPr) and Co (3MeOsalen) were successfully synthesized. These carriers exhibited selective sorption for oxygen to nitrogen and Co (salPr) was better than Co (3MeOsalen). The synthesis of two other types of oxygen carriers, namely, Co (saltmen) and Co (3MeOsaltmen) were also tried. They did not show any selectivity for oxygen transport due to the problem encountered in the synthesis of the amine from dinitrobutane.(2) Production of Oxygen Enriched Air By Liquid Membrane : A new experimental apparatus for the measurement of gas permeation rate was set up and the selective transportation of oxygen was examined with Co (salPr) diluted in various solvents and supported by microporous polymer membranes. The maximum oxygen content of 79% was obtained with 1 : 1 mixutre of dimethylsul-foxide and dimethylacetamide. The selective oxygen transport was well explained by the mechanism with a reversible, instantaneous reaction of oxygen and the carrier. This carrier was found to become less active due to the irreversible oxidation. The choice of solvent was important. Among those examined, 1 : 1 mixture of dimethylsulfoxide and butyrolactone showed least degradation. It was also exhibited that the recharge of the organic phase was effective.

(1)氧载体的合成与评价：在钴基氧载体中，成功合成了Co(salPr)和Co(3MeOsalen)。这些载体表现出对氧气到氮气的选择性吸附，并且 Co (salPr) 比 Co (3MeOsalen) 更好。还尝试了其他两种类型氧载体的合成，即Co（saltmen）和Co（3MeOsaltmen）。由于从二硝基丁烷合成胺时遇到的问题，它们没有表现出任何氧气传输选择性。(2)通过液膜生产富氧空气：建立了一种用于测量气体渗透速率的新实验装置，并用稀释在各种溶剂中并由微孔聚合物膜支撑的Co(salPr)来检查氧气的选择性传输。使用二甲基亚砜和二甲基乙酰胺的 1:1 混合物获得了 79% 的最大氧含量。氧气与载体的可逆、瞬时反应的机制很好地解释了选择性氧运输。发现该载体由于不可逆氧化而活性降低。溶剂的选择很重要。在所检查的那些中，二甲亚砜和丁内酯的1:1混合物显示出最少的降解。还表明有机相的补给是有效的。
