Abstract
The limiting rate of oxidation of tetralin catalyzed by cobalt, manganese, and copper decanoates has been measured in 12 solvents at 65 °C. This rate is generally determined by the kinetic condition that the hydroperoxide reaches a steady-state concentration but the experimental rates are smaller than expected in some solvents. Both cobalt and manganese are able to terminate reaction chains and they therefore act as inhibitors of the oxidation at high concentrations. The ratio of the propagation rate constant (k3) to the square root of the termination rate constant (k6) for the oxidation of tetralin in acetic acid solution is given by[Formula: see text]
