 acid residue an atom of calcium comes, add about 1 volume of 9OCYoigen alcohol to one volume of this mixture and leave for several hours. The calcium salt of the carbohydrate phosphoric acid ester is filtered off and washed with aqueous alcohol. The phosphate is thus converted quantitatively into carbohydrate phosphoric acid ester.

PATENT ANSPRÜCHE : 1. Verfahren zur Darstellung von Kohlehydratphosphorsäureestern bzw. deren Salzen aus mit lebender Hefe gärungsfähigem Zucker oder aus Material, welches solchen Zucker enthält (besonders Maische), und anorganischen Phosphaten, dadurch gekennzeichnet, dass die zur Verwendung gelangende lebende Hefe mit Stoffen versetzt wird, durch welche die Gärwirkung geschwächt oder gehemmt wird, z. B. mit Protoplasmagtften bzw. antiseptischen Mitteln, wie Toluol, Tymol, Chloroform, Phenol, Formaldehyd, Fluornatrium und dgL 2. PATENT CLAIMS: 1. A method for the preparation of carbohydrate phosphoric acid esters or their salts from sugar fermentable with living yeast or from material which contains such sugar (especially mash), and inorganic phosphates, characterized in that the living yeast used is mixed with substances by which the fermentation effect is weakened or inhibited, z. B. with protoplasmagtften or antiseptic agents such as toluene, tymol, chloroform, phenol, formaldehyde, fluorosodium and the like 2. Verfahren zur Herstellung von Kalziumsalzen aus den Lösungen der nach Anspruch 1 hergestellten Kohlehydratphosphorsäureestern bzw. aus deren Alkalisalzen, dadurch gekennzeichnet, dass die betreffenden Lösungen durch Zusatz von Ammoniak und Magnesiumsalzen zunächst von den freien Phosphaten befreit und dann mit einer gesättigten Lösung eines Kalzium- salzes versetzt werden, wobei das gebildete Esterkalziumsalz ausfällt, worauf der Niederschlag mit Alkohol behandelt, abfiltriert und gewaschen wird. Process for the production of calcium salts from the solutions of the carbohydrate phosphoric acid esters produced according to claim 1 or from their alkali salts, characterized in that the solutions in question are first freed from the free phosphates by adding ammonia and magnesium salts and then mixed with a saturated solution of a calcium salt are, the resulting ester calcium salt precipitates, whereupon the precipitate is treated with alcohol, filtered off and washed.
