l'hydrolyse d'une solution de lactose, l'oxydation du mélange de glucose et de galactose ainsi obtenu en un mélange des acides gluconique et galactonique, la décarboxylation de ce mélange des acides gluconique et galactonique en un mélange de D-arabinose et de D-lyxose, l'hydrogénation catalytique de ce mélange de D-arabinose et de D-lyxose en D-arabitol. Process for the preparation of D-arabitol characterized in that it comprises the following stages: hydrolysis of a lactose solution, the oxidation of the mixture of glucose and galactose thus obtained into a mixture of gluconic and galactonic acids, decarboxylation of this mixture of gluconic and galactonic acids into a mixture of D-arabinose and D-lyxose, the catalytic hydrogenation of this mixture of D-arabinose and D-lyxose to D-arabitol. |
