Cobalt tetraaminophthalocyanine was modified by butanedioic anhydride and maleic anhydride to get two aqueous cobalt phthalocyanines. The catalytic oxidation activity of these two cobalt phthalocyanines toward 2-mercaptoethanol was measured, and the effects of pH, temperature and time on the catalytic oxidation activity were investigated. The results reveal the best catalytic oxidation activity at pH 11. The catalytic oxidation activity was improved with the rising of temperature.

Key words: cobalt phthalocyanine, butanedioic anhydride, maleic anhydride, catalytic oxidation
