METHOD FOR THE PRODUCTION OF SORBIT BY HYDROGENATION OF SUITABLE MONO- AND DI-SACCHARIDES ON A RU/SIO2 CATALYST

摘要

The present invention relates to hydrogenated in the liquid phase by catalytic hydrogenation monosaccharide formation D-sorbite described for producing D-sorbite, it is characterized in that the catalyst by 1) single or multiple processing i) by the aqueous solution of the halogen-free low molecular weight ruthenium compound of the carrier material based on amorphous silica and subsequent dried carrier material in temperature less than 200 °, II) the obtained solid of reduction I) and hydrogen in temperature from 100 to 350 °, wherein in step i) directly progress step ii afterwards).
