Complexes of copper(II) with AN-251 anion exchanger and their catalytic activity in the oxidation of n-butyl mercaptan

Abstract

1. Kinetic investigations and EPR spectroscopy have shown that in the oxidation of n-butyl mercaptan with molecular oxygen in the presence of Cu(AN-251) complexes the more coordination-saturated structures (with respect to nitrogen) show the higher catalytic activity. 2. By varying the presorption treatment (protonation of the functional groups of the ion exchanger) and the content of Cu(II) ions one can change the composition and structure of the polymer-metal complexes, thus influencing their catalytic activity.
