ABSTRACT:
Metal salts or substitutted or non-substituted ammonium salts of ascorbic acid derivatives can be produced in high yield by treating an acidic aqueous solution containing ascorbic acid-2-phosphate or ascorbic acid-2-sulfate with a porous adsorbent such as activated carbon, followed by treating the adsorbent with a basic aqueous solution containing e.g. a metal salt of an organic acid or substituted or non-substituted ammonium salt ion to elute the desired salt of ascorbic acid derivative.
