    摘要: The invention relates to an improved process for the production of a sugar alcohol from the corresponding sugar through catalytic hydrogenation. Especially, the invention relates to a process for reducing the interference of sugar-derived aldonic acids in the hydrogenation process by adjusting the hydrogenation conditions so that the activity of the catalyst is maintained. In one embodiment of the invention, the process of the invention is carried out by adjusting the hydrogenation temperature by starting the hydrogenation at a lower temperature and then gradually rising the temperature to the final hydrogenation temperature. In another embodiment of the invention, the process of the invention is carried out by adding small-molecular monocarboxylic acids to the hydrogenation solution.
