Abstract
By mass balance of the acetic acid coordinately bound to cobalt ions exchanged on a sulphonated macroporous styrene-divinylbenzene copolymer, the existence of heterogenized cobalt acetate complexes was confirmed and their amount was determined. It was found that the amount of these complexes depends on crosslinking of the copolymer and on the specific surface of its particles. The dependences found were in good agreement with earlier observed effects of these parameters on the catalytic and sorption activity of macroporous ion exchangers. The catalytic activity of heterogenized cobalt acetate complexes was tested in hydrogen peroxide decomposition at 30 °C. It was found that bromide ions do not exert synergetic effect observed on using these complexes as the catalysts for oxidation with gaseous oxygen.
