Abstract

ABSTRACT:In recent years, catalytic properties of gold have played a major role in the chemistry of environmentally safe substances. In this study, propionic acid was synthesized using electrochemical oxidation on a gold plate electrode in potassium hydroxide. Five hours of electrochemical reaction at a constant voltage was carried out using the chronocuolometry method. Propionaldehyde was oxidized electrochemically to propionic acid as verified by the characterization data from high performance liquid chromatography and Fourier transform infrared spectroscopy. The proposed mechanism of the reaction showed the importance of the OH -species in the synthesis reaction.
