摘要： PURPOSE:To prepare a high purity sorbitan useful as a raw material of food additives (e.g. emulsifier) and a drug, economically, by passing an aqueous solution of dehydrated D-sorbitol through a column packed with a cation exchanger adsorbed with an alkaline earth metal. CONSTITUTION:D-Sorbitol is dehydrated to obtain an aqueous solution containing unreacted D-sorbitol, sorbitan, and isosorbide (two water molecules are removed from D-sorbitol). The solution is passed through a column packed with a cation exchanger having adsorbed alkaline earth metal (Ca, Ba, Mg or Sr; esp. Ca), and the adsorbed sorbitan is eluted with water to obtain highly pure sorbitan. A cation exchange resin, a cation exchange fiber or a cation exchange sephadex can be used as the cation exchanger, however, a sulfonic acid-type strongly acidic cation exchange resin is most effective.

摘要： PURPOSE: To obtain the titled compound useful as a raw material for a nucleic acid seasoning, etc. industrially and advantageously, by epimerizing an aqueous solution of D-arabinose in the presence of molybdenum ions under heating, and separating the reaction solution with a muitivaient metallic cation exchanger column.
CONSTITUTION: An aqueous solution of D-arabinose is subjected to the epimerization in the presence of molydbenum ions, e.g. anion exchanger fibers supporting the molybdenum ions, under heating and filtered. The resultant filtrate is then desalted with an ion exchange resin to give a transparent aqueous solution containing a mixture of D-ribose with pentose. The resultant aqueous solution is then passed through a column of a di- or trivalent metallic cation exchanger, e.g. an ion exchanger prepared by treating a polyvinylsulfonic acid type cation exchange resin with an aqueous solution of calcium chloride, to separate D-arabinose (I), D- ribose (II) and D-xylose and D-lyxose (III).

摘要： 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).

摘要： PURPOSE: To obtain D-mannose useful as a raw material for D-mannitol or a culture medium for microorganisms in high purity and yield, by decomposing an alkali metallic hydrogensulfite adduct of D-mannose with hydrogen peroxide.
CONSTITUTION: An aqueous solution of an alkali metallic hydrogensulfite adduct of D-mannose expressed by formula I (M is Na or K) is decomposed with H
2 O
2 in the presence of an alkaline earth metallic hydroxide, e.g. Ca(OH)
2 , while keeping the pH at about neutral at 60°C or below, and the decomposed solution is purified by an ion exchange resin to give the aimed compound expressed by formula II. The addition and desalting of the alkaline earth metallic hydroxide may be carried out after the decomposing reaction or the purifying treatment with the ion exchange resin. The D-mannose can be completely decomposed without isomerization, polymerization or decomposition. The desalting and the purification with the ion exchange resin can be completely carried out due to no sulfite present in the decomposed solution.
