Abstract
PURPOSE: To obtain the titled compound useful as a raw material for a seasoning, etc. industrially and advantageously, by decarboxylating a D-gluconate salt with hydrogen peroxide in the presence of a ferric salt, epimerizing the decarboxylation product in the presence of molybdenum ions, and separating the titled compound with a multivalent metallic cation exchanger.
CONSTITUTION: An aqueous solution of a gluconate salt is reacted with hydrogen peroxide in the presence of a ferric salt, e.g. ferric gluconate, and decarboxylated and decomposed to give a mixed saccharide solution containing D-arabinose essentially. The resultant solution is then epimerized in the presence of molybdenum ions under heating to give an aqueous solution of a mixed saccharide containing D- arabinose and D-ribose essentially. The solution is further passed through a column of a di- or trivalent metallic salt, cation excahnger, e.g. calcium polyvinylsulfonate, to separate D-arabinose (I), D-ribose (II), D-xylose and D-lyxose (III) and by- products (IV).
