Description
Verfahren zur Herstellung eines Kalziumphosphatkarbonat-Iwischsalzes zu Ernährungszwecken. Es ist ,bereits bekannt, Dikalziumphosphat unter Verwendung von Kalzi,wmkarlbonat als Ausfällungsmittel .zu erzeugen. Ebenso ist es bekannt, daß das zur V erfütterung kommende Dikalziumphosphat stets wenig ,kohlensauren Kalk enthält.Process for the preparation of a calcium phosphate carbonate intermediate salt for nutritional purposes. It is already known to use dicalcium phosphate of calcium carbonate as a precipitating agent. It is also known that the dicalcium phosphate used for feeding is always low in carbonate of lime contains.
Bei :den bekannten Verfahren zur Herstellung zon Dikalzi.umphosphat war so viel Kalziumkarbonat zu den sauren Lösungen gegeben worden, wie mir Bildung des Dikalziumphosphates gerade notwendig ist, ohne daß von einem Überschuß des Fällum;gsmittel:s die Rede war. Die allein als Fällungsmittel benutzte Ka3kmilch ließ durch Reaktion mit der Kohlensäure der Luft wenig Kalzkin#karbonat neben anderen, ein technisches Produkt stets begleitenden Verunreinigungen enstehen, so ,laß -dieses wenige Kalziumkar#bonat ein zufälliger Gemengeteil ist, der erst während des Aribeits-ganges unerwünscht entstanden ist.In: the known processes for the production of dicalcalium phosphate so much calcium carbonate had been added to the acidic solutions as education had been given to me of the dicalcium phosphate is just necessary without an excess of the precipitate; the talk was. The milk, used solely as a precipitant, allowed to react with the carbonic acidity of the air, little calcine carbonate among others, a technical one Product always accompanying impurities arise, so leave this little calcium carbonate is a coincidental part of the mixture, which is only undesirable during the course of work originated.
Bei der vorliegenden Erfindung hingegen wird zur Ausfällung ider sauren Lösungen ein berechnetes Gemenge von Kalzium,hydroxyd und Kalziumkarbonat verwendet, so daß sich ein 1Zischsalz von einer von vornherein genau festgelegten Zusammensetzung ergibt, das neben viel Kalziumkarbonat in feinstverteilter Form enthält. Der Gebrauch dieses Mischsa:lzes gegenüber dem von gewöhnlichem, Präzipitat kommt, wie sich in der Fütterungspraxis ergeben hat, den tatsächlichen Ernährungsverhältnissen weit näher.In the present invention, on the other hand, the precipitation is acidic Solutions uses a calculated mixture of calcium, hydroxide and calcium carbonate, so that there is a Zischsalz of a precisely defined composition from the outset results, which contains a lot of calcium carbonate in finely divided form. The use this mixed salt compared to that of ordinary, precipitate comes as shown in feeding practice has shown far the actual nutritional conditions closer.
Das neue Verfahren besteht darin, :daß zu den sauren Lösungen der Phosphate. die wesentlich freie Phosphorsäure und Monokalziu.mphosphat enthalten, erst Kalkmilch bis zur beginnenden Niederschlagsbildung, ?d. h. bis zur Neutralisation des ersten Äquivalentes der Phosphorsäure, gegeben wird, dann wird unter ständig stärkstem Bewegen der Flüssigkeit so viel Katziumkarbonat eingerührt, wie sich .unter Zugrundelegung der Menge des Ausgangsphosphates rund des gewünschten Prozentgehaltes des Mischsalzes an Phosphorsäure stöchiometrisch berechnen läßt. Unter Koh.lensäureentwicklungbildet sich aus: dem Monokalznumphosphat Idas Dnkalziumphosphat. Sobald die Lösung nur noch schwach saure Reaktion zeigt, wind sie vom entstandenen Niederschlag getrennt, der nach dem Auswaschen bei geeigneter Temperatur getrocknet wird.The new process consists in: that to the acidic solutions of the Phosphates. which contain essentially free phosphoric acid and monocalcium phosphate, first milk of lime until precipitation begins,? d. H. until neutralization of the first equivalent of phosphoric acid, is given, then is under constantly With the strongest movement of the liquid, stir in as much catium carbonate as can be found below Based on the amount of starting phosphate around the desired percentage of the mixed salt of phosphoric acid can be calculated stoichiometrically. Forms under the evolution of carbonic acid consists of: the monocalcnum phosphate Idasdincalcium phosphate. Once the solution only still shows a weakly acidic reaction, it is separated from the precipitate formed, which is dried after washing at a suitable temperature.
Bei :diesem; Verfahren fällt Idas Kalziurcnphosphatkarbonat-Mischsalz als ein zartes weißes Pulver an; die enthaltene Phosphorsäure ist fast durchweg löslich in Ammoonzitrat, was als ein Zeichen dafür anzusehen ist, daß nur geringe Mengen Trikalziumphosphates sich gebildet haben. Unter ;gewissen Verhältnissen kann es zweckmäßig sein, die gesamte Neutralisation bzw. Fällung mit Kalziumkarbonat durchzuführen.At: this one; Process falls into the calcium phosphate carbonate mixed salt appear as a delicate white powder; the phosphoric acid contained is almost entirely soluble in ammoon citrate, which is to be regarded as a sign that only a small amount of Amounts of tricalcium phosphate have formed. Under; certain conditions can it may be useful to carry out the entire neutralization or precipitation with calcium carbonate perform.
