Sugar mixtures comprising glucose and either mannose, fructose, or both, are catalytically hydrogenated in aqueous colution containing 0.2-1.5% by weight (based on sugar) of sodium carbonate or other basic reacting alkali metal salt, yielding mannitol-rich solutions of sorbitol and mannitol. Hydrogenation is preferably carried out in two stages the first at temperature of about 60 DEG -100 DEG C., the second at temperatures of about 110 DEG -160 DEG C. |
