Abstract

Processes for preparing aromatic carboxylic acids. Cinnamaldehyde is hydrogenated to produce a mixture of hydrogenation products, namely, hydrocinnamaldehyde and hydrocinnamic alcohol. The mixture is then oxidized using a suitable oxidizing agent to substantially completely convert both hydrocinnamaldehyde and hydrocinnamic alcohol to hydrocinnamic acid.
