| titleOfInvention | Process for the preparation of salts of ascorbyl-2-phosphoric acid esters |
| abstract | M Natrium, Kalium, Magnesium, Aluminium; P k⊕ Wertigkeit und m = Äquivalente, wobei das Produkt aus k·m 3nbis 5 sein kann, ndadurch gekennzeichnet, daß mann a) Calcium-L-ascorbat-2-phosphat in einer wäßrigen Lösung vonnAscorbyl-2-phosphorsäureestern bei einem pH-Wert von 0,5 bisn4 löst, b) aus der erhaltenen Lösung die Calciumionen entfernt, c) die verbleibende Lösung mit Natrium-, Kalium-, Magnesium- odernAluminiumsalzen auf einen pH-Wert von 7 bis 11 einstelltnund d) die Salze der Ascorbyl-2-phosphorsäureester der allgemeinennFormel I isoliert. Process for the preparation of salts of the ascorbyl-2-phosphoric acid esters of the general formula I, in which the variables have the following meaning: M Sodium, potassium, magnesium, aluminum; P k⊕ Valency and m = equivalents, where the product of k · m can be 3 to 5, characterized in that one a) dissolving calcium L-ascorbate-2-phosphate in an aqueous solution of ascorbyl-2-phosphoric acid esters at a pH of 0.5 to 4, b) the calcium ions are removed from the solution obtained, c) the remaining solution with sodium, potassium, magnesium or aluminum salts to a pH of 7 to 11 and d) the salts of the ascorbyl-2-phosphoric acid esters of the general formula I are isolated. |
