ABSTRACT:
Potassium magnesium L-ascorbate 2-phosphate is prepared from an aqueous solution of potassium L-ascorbate 2-phosphate which is highly contaminated with KCl, as is produced in the phosphorylation of 5,6-isopropylidene-L-ascorbic acid, by adding to the solution about 1 equivalent of magnesium ions per equivalent of L-ascorbate 2-phosphate, and subsequently removing the KCl by electrodialysis. The product of this process is a novel salt of L-ascorbic acid 2-phosphate and has very advantageous handling properties.
