The catalytic oxidation of 2‐mercaptoethanol was investigated kinetically for the system cobalt(II)phthalocyanine‐tetra (sodium sulphonate) in the presence of poly(quaternary ammonium salts) at pH = 8.85. From a comparison with other kinetic data a reaction mechanism could be proposed in which the specific effects of the polyelectrolyte become manifest. The effect of ionic strength on the catalytic activity was also studied. The soluble catalytic system was immobilized on latex particles by using a polymeric soap containing quaternary ammonium groups. The latex particles with the ammonium groups at the surface were used to bond the cobalt catalyst by ionogenic interaction. Using this latex supported polymeric catalyst the activity of its homogeneous counterpart could be maintained while at the same time immobilization was accomplished.
