  • Process for isomerization of compound of aldose structure into compound of ketose structure, and isomerization agent or accelerator used therein
    Patent number: 5679787
    Abstract: A process is provided which comprises isomerizing 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): ##STR1## Due to the use or presence of the organogermanium compound, the process is free from the problems of the prior art, and is 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.
