摘要
用电化学方法合成环氧化合物的研究已有报道,对电环氧化机理的研究却较少.本工作利用循环伏安法和旋转电极法初步探讨了环己烯的电化学环氧化反应机理. 主要仪器有HR-101型双恒电势仪;HR-10lA型旋转电极;HA-501型恒电势仪等. 所用试剂均为分析纯.
The electrochemical epoxidation of cyclohexene has been invest gated on Pt anode inH_2O-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 thatcyclohexene was oxidized into epoxycyclohexane by an EC catalytic mechanism:' Bt- + H2O---HBrO + H+ + 2e?The calculated rate constant k_1 of the second reaction was (2.1±0.4)×10^(-2)·s^(-1).
