Abstract
In this work, a polymer heterogeneous Pt-containing catalyst based on a mesoporous matrix of hypercrosslinked polystyrene (HPS) is proposed for the process of hydrolytic oxidation of cellobiose. Studies of the processes of hydrolytic oxidation of disaccharides are the first step towards the development of technologies for the direct conversion of plant polysaccharides, primarily cellulose, into aldonic and aldaric acids, which are widely used in chemical synthesis and various industries. It was shown that the use of Pt-containing catalytic systems based on a polymer matrix of hypercrosslinked polystyrene in the process of hydrolytic oxidation of cellobiose to gluconic and glucaric acids is promising. The yield of gluconic and glucaric acids reaches 21.6 and 63.4%, respectively.
