Summary
Sulfonic acid cation-exchange resin usually synthesized from styrene divinylbenzene copolymers are not well effective as catalysts of oligosaccharides hydrolysis. The present paper deals with the rate of hydrolysis of oligosaccharides on a new cation exchanger obtained by grafting sulfonic groups on porous silica. With the large pore sizes, the sieving effect of large solutes is suppressed and the catalytic activity is comparable with that of polystyrenesulfonic acid in homogeneous phase.
