ABSTRACT:
A method of obtaining D-glucuronic acid. The D-glucuronic acid and its derivatives (lactone, salts, amides, etc.) are biologically high-active compounds, which are widely used in medicine and pharmaceutical chemistry for the synthesis of modified drugs as well as used as food additives, skin-care preparations, and the like. This invention provides an environmentally friendly method of obtaining D-glucuronic acid which has widespread operational possibilities. The D-glucuronic acid is obtained by heating the salts of 1,2-0-isopropylidene-D-glucuronic acid in a water-containing solution in the presence of an acid agent, for which sulphonic acid cation exchanger resins are used.
