摘要：

The platinum catalyzed oxidation of sucrose by oxygen has been studied. With platinum on carbon at 100-degrees-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 C-13 spectrum of 6-carboxysucrose was then assigned by difference.
