Study on catalytic oxidation of planar binuclear copper phthalocyanine on 2-mercaptoethanol

Mononuclear copper phthalocyanine (CuPc) and binuclear copper phthalocyanine (Cu2Pc2) were synthesized by the phenylanhydride-urea route, and their catalytic oxidation activity on 2-mercaptoethanol was studied. Based on the experimental results, a catalytic mechanism of Cu2Pc2 on 2-mercaptoethanol has been proposed. Furthermore, the effects of pH, Cu2Pc2 concentration, and temperature on the catalytic oxidation activity were evaluated. The results showed that CuPc has no catalytic activity, while Cu2Pc2 has high catalytic oxidation activity towards 2-mercaptoethanol with the optimal activity at pH 11. The reaction can further be enhanced by increasing Cu2Pc2 concentration and temperature, due to its endothermic characteristics.

苯乙烯-二乙烯苯树脂负载双核钴酞菁对巯基乙醇的催化性能

双核钴酞菁(Co2Pc2)以共价键负载到苯乙烯-二乙烯苯树脂(resin)上得到一种新型的催化功能性材料(resin-Co2Pc2)。考察了pH、催化剂量和温度对resin-Co2Pc2催化巯基乙醇的影响。实验结果表明,resin-Co2Pc2在pH=11时催化活性达到最大;催化活性随反应温度升高而提高,此催化反应为吸热反应,而且resin-Co2Pc2经多次重复使用后其催化活性基本保持不变,具有很好的重复使用性能。
