摘要：

Liquid phase autoxidation of toluene and p-methoxytoluene in acetic acid has been studied under electrolysis in the presence of cobalt acetate. The latency period disappears when Co3+ is electrogenerated in the medium either before or during autoxidation experiments. The kinetics of the oxidation process is accelerated under electrolysis condition. The effects of temperature, current intensity, Co concentration, oxygen flow rate are investigated. The transition between the kinetic and the mass transfer limitations is determined in the case of p-methoxytoluene. (C) 1999 Elsevier Science B.V. All rights reserved.
