Verfahren zur Herstellung einer Tannin, Hexamethylentetramin und Calcium enthaltenden
Verbindung.
Die Herstellung von Tannin-Calcium-Verbindungen ist bekannt, es war aber nicht bekannt, dass man in Wasser schwer lösliche alkalilösliche Verbindungen bekommt, wenn man konzentrierte Chlorcalcium-Hexamethylentetramin-Lösungen mit Gerbsäure fällt. Die so erhaltenen Substanzen lassen sich auf in Salzsäure schwer lösliche Tannin-Calcium-Eiweissverbindungen weiter verarbeiten, indem man sie in Salzsäure löst und mit Eiweisslösung fällt.
Beispiel : Zu einer Lösung von 10 g Chlorcalcium in etwa 40 g Wasser wird eine Hexamethylentetramin-Lösung hinzugegossen, welche in ungefähr 40 g Wasser 10 g Hexamethylentetramin enthält. Giesst man zu dem Gemisch eine Lösung von 15 g Tannin in 60 g Wasser, so erhält man einen Niederschlag, welcher abfiltriert, gewaschen und getrocknet, ein weisses Pulver darstellt, das in Wasser wenig löslich ist, sich jedoch bei ungefähr 800 löst. Setzt man zu der Aufschwemmung des Pulvers in kaltem Wasser konzentrierte Salzsäure, so geht der Niederschlag vollkommen in Lösung, bei weiterem Zusetzen von Säure tritt hingegen Trübung und schliesslich Fällung ein. Der Niedeischlag ist in Alkali leicht löslich.
Beispiel 2 : iog der nach Beispiel i erhaltenen Substanz werden in 150 g Wasser aufgeschwemmt und schwach erwärmt. Zu der vorgewärmten Lösung wird unter Rühren so lange tropfenweise konzentrierte Salzsäure zugesetzt, bis vollständige Lösung eingetreten ist, was etwa 4 ccm Salzsäure erfordert. Man kühlt ab und versetzt die Lösung mit etwa 50 ccm einer lodigen Bluteiweisslösung, wobei ein Niederschlag ausfällt, welcher bei etwa 23% Tanningehalt, Calcium, Eiweiss und Hexamethylentetramin enthält. Der Niederschlag wird abfiltriert, gewaschen und getrocknet. Das Präparat ist in Wasser und Salzsäure schwer löslich, wird aber von Alkalien sichtlich sofort angegriffen und bei Zimmertemperatur langsam, hei höherer Temperatur schneller gelöst.

Process for the preparation of a tannin containing hexamethylenetetramine and calcium
Connection.
The production of tannin-calcium compounds is known, but it was not known that alkali-soluble compounds that are sparingly soluble in water are obtained if concentrated calcium chloride-hexamethylenetetramine solutions are precipitated with tannic acid. The substances obtained in this way can be further processed into tannin-calcium-protein compounds, which are sparingly soluble in hydrochloric acid, by dissolving them in hydrochloric acid and precipitating them with protein solution.
Example: To a solution of 10 g of calcium chloride in about 40 g of water, a hexamethylenetetramine solution is added which contains 10 g of hexamethylenetetramine in about 40 g of water. If a solution of 15 g of tannin in 60 g of water is poured into the mixture, a precipitate is obtained which, filtered off, washed and dried, is a white powder that is sparingly soluble in water, but dissolves at about 800. If concentrated hydrochloric acid is added to the suspension of the powder in cold water, the precipitate dissolves completely, but if further acid is added, clouding and finally precipitation occur. The precipitate is easily soluble in alkali.
Example 2: iog the substance obtained according to example i are suspended in 150 g of water and gently warmed. Concentrated hydrochloric acid is added dropwise to the preheated solution with stirring until complete dissolution has occurred, which requires about 4 cc of hydrochloric acid. It is cooled and about 50 cc of an iodine blood protein solution is added to the solution, a precipitate separating out which contains calcium, protein and hexamethylenetetramine at about 23% tannin content. The precipitate is filtered off, washed and dried. The preparation is sparingly soluble in water and hydrochloric acid, but is visibly attacked immediately by alkalis and dissolves slowly at room temperature and more rapidly at higher temperatures.
PATENT CLAIMS: i. Process for the preparation of a compound containing tannin, hexamethylenetetramine and calcium, characterized in that a solution containing hexamethylenetetramine and calcium chloride is precipitated with tannin.
