ABSTRACT:
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.
