The processes can be explained by the fact that the association constant(K_(assoc)) values of MgTPP with amines were in the range of 0.6(ethanolamine) to 3.9(ethylenediamine),which are lower than the K_(assoc) values of CO_2 with these amines.MgTPP interacted with aniline,ethanolamine,pyrrolidine,or ethylenediamine to form 1:1 adducts.Ethylenediamine presents a stronger K_(assoc) value for MgTPP,so it was considered an optimal agent for CO_2 capture. 关键词：四苯基卟啉乙醇胺超分子二氧化碳结合功能捕获镁 C02
