It is a naturally occurring aldaric acid, typically found in small amounts in a variety of fruits and vegetables. It is a highly functionalized compound with four chiral carbons and a plethora of reaction pathways. Its commercial potential was unveiled in the report “Top Value Added Chemicals from Biomass” from the Department of Energy of USA which described its use as a building block for a number of polymers, including new nylons and hyperbranched polyesters. Process technologies 1,3,4,5,6,7,8 The synthetic preparation of D-glucaric acid dates back to a report of Sohst and Tollens (1888) who carried out the nitric acid oxidation of D-glucose to D-glucaric acid. Current methods for its production are based on this process and in
