PROCESSES FOR PREPARING ALDARIC, ALDONIC, AND URONIC ACIDS
-
Paragraph 0132-0143, (2021/05/29)
Various processes for preparing aldaric acids, aldonic acids, uronic acids, and/or lactone(s) thereof are described. For example, processes for preparing a C5-C6 aldaric acid and/or lactone(s) thereof by the catalytic oxidation of a C5-C6 aldonic acid and/or lactone(s) thereof and/or a C5-C6 aldose are described.
OXIDATION OF URONIC ACIDS TO ALDARIC ACIDS
-
Paragraph 0032; 0037, (2017/11/10)
Disclosed is the oxidation of uronic acids, such as galacturonic acid, to the corresponding aldaric acids, such as galactaric acid, under neutral or acidic conditions. Use is made of a supported gold catalyst. The oxidation occurs in good selectivity and yield, under unexpectedly mild conditions. A source of galacturonic acids is pectins, such as from sugar beet pulp.
Novel synthetic process of mucic acid

Paragraph 0035-0037; 0067, (2017/06/10)
The present invention relates to a method of synthesizing mucic acid from galactose derived from biomass including marine resources, and more specifically, to a method of synthesizing mucic acid which utilizes galactose as a starting material and through a chemical reaction, induces an oxidation reaction to synthesize mucic acid. The method of the present invention can easily synthesize mucic acid in a high yield from galactose and the like under low temperature and atmospheric pressure operating conditions, can be used as an intermediate to produce bio adipic acid, the raw material of nylon 66 that is used as a material for automobile parts, and, therefore, has high industrial applicability.(AA) Marine bio sugar mixture obtained after saccharification using non-food marine resources (galactose, or a mixture of galactose, glucose and rhamnose)(BB) Mixing of aqueous nitric acid solution with sugar mixture(CC) Oxidation reaction of bio sugar under low temperature condition (-15~0anddeg;C)(DD) Washing of solid products produced from chemical reaction and extraction of high-purity mucic acid particles using aqueous solution, having mucic acid dissolved therein, prepared in advanceCOPYRIGHT KIPO 2017
