  • Methods for the production of calcium, magnesium, and zinc salts of sugar acids
    Patent number: 12630578
    Abstract: A method has now been found for the preparation of calcium, magnesium, and zinc salts of sugar acids, this being the object of the present invention, which is characterized in that the method may include providing a sugar and oxidizing the sugar to a sugar acid in the presence of a noble metal catalyst, oxygen, and a heterogeneous hydroxide source. Preferably the oxidation is carried out with a gold catalyst, and a heterogeneous source of magnesium, calcium, or zinc hydroxide. The oxidation can be performed in a batch or continuous manner.

  • Processes for the production of xylitol
    Publication number: 20050272961
    Abstract: Methods of producing xylitol comprising the oxidative decarboxylation of a reactant substrate are provided herein. The oxidative decarboxylation is performed in one of two ways. In the first, the oxidative decarboxylation is performed by an electrochemical process, preferably an anodic odixative decarboxylation of a reactant substrate. In the second, the oxidative decarboxylation of the reactant substrate is carried out by a series of oxidation-reduction chemical reactions.
