This application discloses a highly selective method for preparing hexonic acid. This method uses hexuronic acid as a substrate and prepares hexonic acid through a three-step process of esterification, oxidation, and hydrolysis. The first step involves protecting the hydroxyl groups on hexuronic acid with an organic acid / anhydride. The second step uses molecular oxygen as an oxygen source to oxidize hexuronic acid to hexonic acid ester under the synergistic catalytic oxidation of metal ions and halogens. The third step hydrolyzes the hexonic acid ester to obtain hexonic acid. This invention offers high selectivity and is environmentally friendly, providing a novel method for the preparation of hexonic acid.
