Effects of ionenes on structure and catalytic activity of cobalt phthalocyanine. VI : Hydrogen peroxide accumulation
Accumulation of hydrogen peroxide during the catalytic oxidation of 2-mercaptoethanol in the presence of CoPc(NaSO 3 ) 4 /2.4-ionene was investigated. It appeared to be the result of H 2 O 2 formation via the catalytic reaction step and subsequent decomposition by further reaction with thiol. The decomposition process was found to follow first-order kinetics in both H 2 O 2 and RS − , whereas the formation step could be described by a two-substrate Michaelis-Menten rate equation
