Abstract

Kinetics and different process parameters for the air oxidation of veratraldehyde to veratric acid were studied. At a temperature of 130 °C, air pressure of 1 MPa, cobalt acetate loading of 0.03 mol/L, and an initial concentration of 30% w/v of veratraldehyde, the reaction was found to be first order with respect to veratraldehyde. In 3 h at an aldehyde conversion level of 100%, as high as 99% selectivity was achieved.
