采用耗氧法研究了4种金属酞菁配合物[α-四(对羧基苯氧基)金属酞菁(Zn,Co)、β-四(对羧基苯氧基)金属酞菁(Zn,Co)]对0.1mol.L-1亚硫酸钠的催化氧化性能,考察了配合物中心金属和取代基的位置对催化活性的影响。研究结果表明中心离子相同时,β位四取代(对羧基苯氧基)金属酞菁的催化活性优于α位;取代基位置相同时,酞菁钴的催化氧化性优于酞菁锌。且β-四(对羧基苯氧基)酞菁钴的浓度为1.00×10-4mol.L-1时,对亚硫酸钠的催化氧化性能最高。
The effects of four kinds of metal phthalocyanine complexes (Zn, Co), β-tetrakis (p-carboxyphenoxy) metal phthalocyanines (Zn, Co )] On the catalytic oxidation of sodium molybdate 0.1mol.L-1, investigated the central position of the complex metal and substituents on the catalytic activity. The results show that the catalytic activity of β-position tetrasubstituted (p-carboxyphenoxy) metal phthalocyanine is better than that of α-position when the center ions are the same. The catalytic oxidation of cobalt phthalocyanine is better than that of phthalocyanine zinc when the substituents are the same. When the concentration of β-tetrakis (p-carboxyphenoxy) phthalocyanine was 1.00 × 10-4 mol·L-1, the catalytic oxidation of sodium sulfite was the highest.
