Abstract: The electrochemical oxidation of cinnamyl alcohol proceeds via consecutive reaction, the follow-up reaction is important in the mediatory systems. The reaction rate de-creased with an increase in water content. An increase in acid concentration also accelares the reaction rate. As expected, the increase of reaction temperature shows an enhancement of the reaction rate for aldehyde and acid formation simultaneously.
