The electrochemical epoxidation of cyclohexene has been invest gated on Pt anode in H₂O-NaBr-MsCN medium using a rotating disk electrode and a rotating ring-disk electrode.The electrolytic products were identified by means of IR and MS. The results show that cyclohexene was oxidized into epoxycyclohexane by an EC catalytic mechanism: Br^-1+H₂O→HBrO+H⁺+2e↕HBrO+CyclohexeneBr^-1+O+H⁺ The calculated rate constant k₁ of the second reaction was (2.1±0.4)×10^-2·s^-1.
