METHOD OF CONVERTING ALDOSE TO KETOS

A process for converting aldoses or derivatives thereof into ketoses or derivatives thereof which takes place in the presence of oxyanions or mixed complex oxyanions of germanium or tin which form stronger complexes with the ketoses or derivatives thereof than with the aldoses or derivatives thereof...

Zusammenfassung:	A process for converting aldoses or derivatives thereof into ketoses or derivatives thereof which takes place in the presence of oxyanions or mixed complex oxyanions of germanium or tin which form stronger complexes with the ketoses or derivatives thereof than with the aldoses or derivatives thereof. Using the process the equilibrium position in the aldose-ketose reaction is shifted towards higher proportions of ketose. The process is very applicable to the conversion of glucose to fructose particularly when this conversion takes place enzymatically in the presence of glucose isomerase.
