Summary
Partition chromatography on anion-and cation-exchange resins in aqueous ethanol is used for the separation of aldoheptitols and various oligomeric sugar alcohols. A straight line relationship exists between the logarithm of the distribution coefficient and the degree of polymerization of oligomers with the same mode of glycosidic bonds. At high ethanol concentration the solutes are eluted in order of increasing size whereas at low ethanol concentration the order is reversed. In each oligomeric series there exists a critical concentration at which all oligomers appear simultaneously.
