Abstract: A kind of soluble planar binuclear metal-phthalocyanine was synthesized and was characterized by element analysis and FT-IR spectra. The effects of pH, concentration of catalytic agent and the various ratios of both binuclear phthalocyanineiron(Ⅲ) and phthalocyaninecobalt(Ⅱ) in mixtures on the catalytic oxidation of 2-mercaptoethanol were studied.The results showed that the catalytic activity of binuclear metal-phthalocyanine was the highest at pH=11 and the catalytic activity of binuclear phthalocyaninecobalt(Ⅱ) was higher than that of binuclear phthalocyanineiron(Ⅲ).Moreover, it was found that catalytic activity of binuclear phthalocyanineiron(Ⅲ) and phthalocyaninecobalt(Ⅱ) mixture was higher and even the best at the ratio of 1∶1, whose reaction mechanism was deeply discussed.

摘要： 合成了一种水溶性平面双核金属酞菁衍生物，用元素分析和红外光谱对其结构进行了表征.研究了双核金属酞菁对巯基乙醇的催化活性与pH值、催化剂浓度以及不同双核金属酞菁混合配比之间的关系.实验结果表明，双核金属酞菁在pH=11时催化氧化活性达到最大，且双核钴（Ⅱ）酞菁比双核铁（Ⅲ）酞菁的催化活性高.实验还首次发现，双核钴（Ⅱ）酞菁和铁（Ⅲ）酞菁混合后具有更高的催化氧化活性，混合比以1∶1时催化活性最高，并对其机理进行了探讨.
