METHOD FOR PREPARATION OF EPIMER FREE SUGAR ALCOHOLS

The sugar alcohols given in the title can be prepared in epimer-free form from the corresponding sugars by catalytic hydrogenation in aqueous solution using hydrogen, the hydrogenation being carried out continuously at 100-500 bar of H2 and 60 DEG -125 DEG C. on a fixed bed of carrier-free mouldings...

Zusammenfassung:	The sugar alcohols given in the title can be prepared in epimer-free form from the corresponding sugars by catalytic hydrogenation in aqueous solution using hydrogen, the hydrogenation being carried out continuously at 100-500 bar of H2 and 60 DEG -125 DEG C. on a fixed bed of carrier-free mouldings composed of pressed powders of the elements of the iron group of the periodic table. The mouldings have a compressive strength of above 50 N and an internal surface of 10-90 m2/g.
