Abstract
Isomaltitol was gained by hydrogenation of isomaltulose. The effects of reaction temperature, pressure, initial isomaltulose concentration and stirring rate on the reaction rate were studied in this paper. The optimal reaction conditions of liquid gas phase on the surface of catalyst were determined as follows: 11 MPa for the pressure, 120~130 ℃ for the temperature,20 g/dL for the initial isomaltulose concentration,50 r/min for the stirring rate. Under those conditions, after two hours, the conversion rate was no less than 99.5%, and the gained isomaltitol could get up to FAO specification.
