Anwendungen

D-(+)-Xylose is used to prepare furfural by acid catalyzed degradation reaction, which acts as a solvent as well as a precursor to synthetic polymers. It is a useful animal medicine involved in the treatment of malabsorption. It finds application in the production of sugar substitute xylitol by subjecting xylose to calyticl hydrogenation process. It is found that it undergoes an atmospheric-pressure enzyme (polyphosphate xylulokinase) driven process to get hydrogen.

Bemerkungen

Store in cool place. Hygroscopic. Incompatible with strong oxidizing agents.
