Nonanol-1 oxidation on nickel oxide electrode with the involvement of active oxygen forms

Abstract

The process of nonanol-1 oxidation is studied on the nickel oxide electrode with the use of chemically bound active oxygen forms (AOF) electrochemically generated in situ from O2, H2O2, and H2O. The effect of electrolysis conditions (AOF generation schemes, current density, passed charge) on the yield of pelargonic acid is studied. The oxidation proceeds most efficiently at the current density of 5–10 mA cm−2 as the theoretical charge is passed in the paired electrolysis mode. The current efficiency with respect to pelargonic acid is 83.7%; the substance yield is 83.8%. In addition to pelargonic acid, several oxidation side-products are found in the electrolyte. Their content increases with the increase in the charge passed as a result of further oxidation of pelargonic acid.
