摘要:
A process for the preparation of D-arabitol, characterised in that it comprises the following stages: hydrolysis of a lactose solution, oxidation of the mixture of glucose and galactose thus obtained to a mixture of gluconic and galactonic acids, decarboxylation of this mixture of gluconic and galactonic acids to a mixture of D-arabinose and D-lyxose, catalytic hydrogenation of this mixture of D-arabinose and D-lyxose to D-arabitol.
