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]

Propagation Rate Constant

The propagation reaction in the anionic polymerization of styrene in oxepane has been studied as a function of temperature and concentration of polystyrylsodium. Conductance measurements on polystyrylsodium were also made together with determinations of density, viscosity, dielectric constant, and dipole moment of oxepane itself. The measurements enabled the propagation rate constant to be determined of the polystyryl anion at 30 °C and of the ion-pair over a wide temperature range. The results have been compared with those obtained in tetrahydrofuran and tetrahydropyran.
