PROCESS FOR ISOMERIZATION OF COMPOUND OF ALDOSE STRUCTURE INTO COMPOUND OF KETOSE STRUCTURE, AND ISOMERIZATION AGENT OR ACCELERATOR USED THEREIN

摘要

The present invention provides a process which comprises isomerizing a compound having an aldose structure into a compound having a ketose structure, by the use of or in the presence of an organogermanium compound having a structural portion represented by formula (I) and an isomerization agent or accelerator effective for the isomerization of a compound having an aldose structure into a compound having a ketose structure, which agent or accelerator comprises, as an active component, an organogermanium compound having a structural portion represented by formula (I). Owing to the use or presence of the above organogermanium compound, said process is free from the problems of prior art and capable of isomerizing a compound having an aldose structure into a compound having a ketose structure at a high isomerization ratio without requiring any special apparatus or any complicated operation.
