Process for purifying L-ascorbic acid 2-phosphate |
摘要 |
A process of purifying L-ascorbic acid 2-phosphate is disclosed, comprising passing a solution containing L-ascorbic acid 2-phosphate through a column of a basic anion exchanger resin whose ion-exchange groups consist essentially of a primary amine group, a secondary amine group, a tertiary amine group or a mixture thereof, and eluting the L-ascorbic acid 2-phosphate with an aqueous solution of a mineral acid or an inorganic salt. L-ascorbic acid 2-phosphate can be isolated at a high efficiency through easy steps.
