Sucrose can be converted to allosucrose by a sequence of a biotechnical oxidation and a hydrogenation. The second step was found to be highly stereoselective with high yield and without any side products. The kinetics of the hydrogenation was examined with respect to the influence of the starting materials and the catalyst. A quantitative correlation for the influence of the concentrations is given. Furthermore, the influence of mass transfer processes was considered. Under unfavorable conditions gas liquid mass transfer can be rate‐limiting.
