THE SEPARATION OF SUGARS ON ION-EXCHANGE RESINS. PART I. SEPARATION OF OLIGOSACCHARIDES

Abstract

Fractionation according to molecular size has been achieved by development of oligosaccharide mixtures with water on columns of neutral salt forms of sulphonic acid type ion-exchange resins. The method was used to separate a synthetic mixture of raffinose, sucrose, and glucose and a number of hydrolyzates of polysaccharides to give clean, salt-free fractions of high purity. The procedure is rapid and economical and provides a useful extension of older methods of separating such mixtures.
