    摘要: A method for synthesizing and isolating an oxidation product is disclosed wherein nitric acid is reacted with an oxidizable reactant and the desired oxidized product is extracted using an organic solvent such as a dialkyl ether. The method permits the direct crystallization of aldaric acids such as glucaric acid and mannaric acid and eliminates the necessity of employing complicated, time consuming and wasteful neutralization/acidification steps.

    摘要: 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.
