Description

Herstellung von viskose Lösungen liefernden stabilen Kaliumphosphaten Es ist bekannt, daß wasserunlösliche Kalium- und Natriumsalze der Metaphosphorsäure, die als Kurrolsche Salze bezeichnet werden, mit Natrium- und Ammoniumsalzen Lösungen ergeben, die durch hohe Viskosität ausgezeichnet sind. Diese Stoffe werden in der Weise gewonnen, daß man Monokal.iumorthophosphat unterhalb des Schmelzpunktes einige Stunden erhitzt und langsam albkühlen läßt. Je höher dabei die Temperatur gewählt wird, desto schneller - soll nach den bisherigen Beobachtungen die Umwandlung vor sich gehen und um so höher soll der Viskositätsgraid der wässerigen Lösungen :der gebildeten Verbindungen sein. Weiter ist festgestellt worden, ,daß der Vi-skositätsgraid wässeriger Lösungen von solchen Stoffen, die bei: höheren Temperaturen, z. B. bei 7oo bis 8oo°, gewonnen worden sind, sinkt, wenn man diese in Gegenwart von r °/o Bleimetaphosphat als Reaktionsbeschleuniger bei niedrigeren Temperaturen, z. B. bei 2&i bis 36o°, einige Zeit erhitzt.Production of stable potassium phosphates that produce viscous solutions It is known that water-insoluble potassium and sodium salts of metaphosphoric acid, which are called Kurrol's salts, with sodium and ammonium salts solutions result, which are characterized by high viscosity. These substances are in the Wise won that one Monokal.iumorthophosphat below the melting point some Heated for hours and allowed to cool slowly. The higher the temperature chosen becomes, the faster - according to previous observations, the transformation should proceed go and the higher should the viscosity range of the aqueous solutions: the be formed connections. It has also been found that the viscosity griev aqueous solutions of such substances, which at: higher temperatures, z. B. at 700 to 8oo °, has been obtained, drops if this is done in the presence of r ° / o Lead metaphosphate as a reaction accelerator at lower temperatures, e.g. B. at 2 & i up to 36o °, heated for some time.

Es wurde gefunden, daß man zu höchst viskose Lösungen lieferndem KaJiurnmetaphosphat gelangt, wenn man Monokaliurnorthophosphat zunächst wenig unterhalb dies. Schmelzpunktes von Kaliummetaphosphat erhitzt und daran anschließend einige Zeit bei darunterliegenden Temperaturen erhitzt. Die so gewonnenen Produkte zeichnen sich noch dadurch aus, da13 sie neben einem hohen Wasch-, F_mulsions- und Kallzbindevermögen besonders stabil gegen die intramolekulare Wasseranlagerung sind.It has been found that calcium metaphosphate which produces extremely viscous solutions can be used if you get monopotassium orthophosphate initially a little below this. Melting point heated by potassium metaphosphate and then for some time with underlying Temperatures heated. the products obtained in this way still stand out characterized by the fact that they have a high washing, emulsion and powder binding capacity are particularly stable against intramolecular water deposition.

Ausführungsbeispiel In einer Platinschale «-erden ioo g Nfonokaliumorthophosphat auf Soo` erhitzt und 3 Stunden diese Temperatur aufrechterhalten. Darauf läht man abkühlen und erhitzt das Produkt -16 Stunden bei 50o°. Die Viskosität der .wässerigen Lösung dieses Präparates in n/io-Natriumhexametapliospliatlösung beträgt 2300- 1o--4. «wohingegen der höchste Viskositätsgehalt bisher bekannter Kurrolscher Salze unter gleichen Bedingungen nur mit 734- io-@ gemessen worden ist.Embodiment In a platinum dish, earth 100 g of potassium orthophosphate heated to Soo and maintain this temperature for 3 hours. It is then allowed to cool and the product is heated at 50 ° for -16 hours. The viscosity of the aqueous solution of this preparation in sodium hexametapliospliate solution is 2300-10-4 . «Whereas the highest viscosity content of Kurrol's salts known to date has only been measured with 734- io- @ under the same conditions.
