Title:
CONVERTING SUGARS TO SUGAR ALCOHOLS BY AQUEOUS PHASE CATALYTIC HYDROGENATION
Document Type and Number:
WIPO Patent Application WO2002088057
Kind Code:
B1
Abstract:
The present invention provides a method of converting sugars to their corresponding sugar alcohols by catalytic hydrogenation in the aqueous phase. It has been found that surprisingly superior results can be obtained by utilizing a relatively low temperature (less than 120°C), selected by hydrogenation conditions, and a hydrothermally stable catalyst. These results include excellent sugar conversion to the desired sugar alcohol, in combination with long life under hydrothermal conditions.
