ABSTRACT:
Process for enrichment of .beta.-anomers of alkyl glycosides of amino sugars involving two steps. The first step comprises treating an equilibrium mixture of the .alpha.- and .beta.-anomers of the alkyl glycosides with an inorganic base under controlled reaction conditions, e.g., specific solvents, water content of solvent and temperature and time of treatment. These conditions cause the equilibrium to shift in favor of the .beta.-anomer. The second step comprises subjecting the product of the first step to multiple fractionations in specific solvent mixtures to isolate products having increased proportions of the .beta.-anomers of the alkyl glycosides of amino sugars.
