摘要: 循环伏安法研究表明2,2′-联吡啶催化Co(Ⅱ)通过水/硝基苯界面的相转移伴有化学反应发生。水相或有机相的伴随化学反应直接影响Co(Ⅱ)与2,2′-联吡啶逐级配合物的相转移的循环伏安行为,并观察到类似于金属电极/电解质溶液界面出现的不可逆渡,不同的配合物,相转移机制不同。

Abstract: The chemical reactions coupled with the phase transfer of Co(Ⅱ) catalyzed by 2,2′ -bipyridine across the water/nitrobenzene interface have been observed by using cyclic voltammetry (CV). Coupled chemical reactions both in the organic phase or in the aqueus phase influence the CV behavior of successive complex phase transfer obviously and an irreversible phenomenon similar to that existed at the metal electrode/electrolyte solution interface was observed. For different complexes, the phase transfer mechanism is different.
