Cellobiose hydrogenation to D-sorbitol using Ru/HPS MN 100 catalyst

This work is devoted to the process of cellobiose (4-O-beta-D-glucopyranosyl-D-glucose) hydrogenation to D-sorbitol, which is valuable raw material for food, chemical, and pharmaceutical industries. The data on the regularities of the catalytic hydrogenation of cellobiose to D-sorbitol are presented in this work. Cellobiose hydrogenation was performed in a batch reactor. The catalytic system presented by 3 wt. % ruthenium supported on the hypercrosslinked polystyrene (HPS) was used as a catalyst for cellobiose hydrogenation. The catalyst was produced by the impregnation of HPS (amino-functionalized MN 100) by the solution of the ruthenium salt in a complex solvent - tetrahydrofuran-methanol-water by the ratio 4:1:1. Before the experiments, the catalyst was reduced in hydrogen flow at the atmospheric pressure and temperature of 573 K. the analysis of the samples of the reaction mixture was performed by the thin-layer chromatography using Sorbfil 100×200 mm chromatographic plate and Sorbfil visualizer.
