ABSTRACT:
A process for preparing diacetone-ketogulonic acid comprises oxidizing diacetonesorbose to diacetone-ketogulonic acid to an extent of about 30-95% by electrochemical oxidation or O.sub.2 oxidation; electrodialysing the resultant reaction solution to separate the pure diacetoneketogulonic acid from the unoxidized diacetonesorbose; and recycling the unoxidized diacetone-sorbose to the oxidation step.
