Abstract
ABSTRACT The platinum catalyzed oxidation of sucrose by oxygen has been studied. With platinum on carbon at 100°C and at constant neutral pH, the oxidation is highly specific for the primary hydroxyls at the 6- and 6′-positions of sucrose. There was no evidence of oxidation of the 1′ hydroxyl. The 6,6′-dicarboxysucrose was resistant to attack by invertase. The 6- and 6′-carboxysucroses could not be resolved from each other, but the former component was hydrolysed rapidly by invertase and subsequently the 6′-carboxysucrose was isolated. The 13C spectrum of 6-carboxysucrose was then assigned by difference.
