Antiozonant activity of the silica modified with 3d metal complexes

Abstract

Criteria for preliminary selection of the antiozonants based on the silica modified with the complexes of 3d metal were proposed and the activity of the antiozonants as a dependence on the nature of the ligands (Schiff bases, Cl−, NO3−) and metal ions [Cu(II), Co(II), Mn(II)] was established. We found that advantageous were complexes MnL2/\(\overline {Si} \), where L denotes a Schiff base of phenol or quinoline series, whose kinetic and specific stoichiometric energy parameters of the reaction were the largest because of the formation during the reaction of the manganese oxide form which performs the catalytic decomposition of ozone.
