    • A process for preparing salts of ascorbyl 2-phosphoric esters of the formula I, ##STR1## where the variables have the following meanings: M is sodium, potassium, magnesium, aluminum; ##STR2## k.sym. is the valence and m=equivalents, where the product of k.multidot.m can be from 3 to 5,comprisesa) dissolving calcium L-ascorbate-2-phosphate in an aqueous solution of ascorbyl 2-phosphoric esters at a pH of from 0.5 to 4,b) removing the calcium ions from the resulting solution,c) adjusting the pH of the solution which remains to from 7 to 11 by means of sodium, potassium, magnesium or aluminum salts andd) isolating the salts of the ascorbyl 2-phosphoric ester of the formula I.
    • 一种制备式I的抗坏血酸2-磷酸酯的方法,其中变量具有以下含义:M是钠,钾,镁,铝; k(+)是化合价,m =等价物,其中kxm的产物可以为3至5,包括:a)将L-抗坏血酸-2-磷酸酯溶解在抗坏血酸2-磷酸酯的水溶液中,pH为 从0.5至4,b)从所得溶液中除去钙离子,c)通过钠,钾,镁或铝盐将溶液的pH调节至7至11,以及d)分离 抗坏血酸2-磷酸酯。
