Description
Aufschlußverfahren für kieselsäurehaltige Erden.Digestion process for siliceous earth.
Die Erfindung betrifft ein Aufschlußverfahren für kieselsäurehaltige Erden, insbesondere Bleicherden. Es ist bekannt, natürliche ton- und kieselsäurehaltige Erden durch Behandlung mit Säuren, insbesonders Salzsäure, aufzuschließen und dadurch ihre Bleich- und Reinigungskraft zu erhöhen. The invention relates to a digestion process for silicic acid Earth, especially full earth. It is known to be natural clay and silica To break down earth by treatment with acids, especially hydrochloric acid, and thereby to increase their bleaching and cleaning power.
Äffion den genannten Verfahren unterscheidet sich das vorliegende dadurch, daß die Säuren, insbesondere Salzsäure oder Schwefelsäure, in chemisch gebundener Form mit der Erde gemischt und während des Aufsclllußverfahrens selbst auf chemischem oder physikalischem ÄVege durch Hydrolyse, Elektrolyse oder durch Zusatz chemisch entsprecherid wirkender Stoffe frei gemacht werden und so in statu nascendi, also in aktivstem Zustand, auf die aufzuschließende Erde einwirken können. Affion of the procedures mentioned differs from the present one in that the acids, especially hydrochloric acid or sulfuric acid, in chemically bound form mixed with the earth and during the decomposition process itself by chemical or physical means by hydrolysis, electrolysis or by Addition of chemically corresponding substances are made free and so in statu nascendi, i.e. in the most active state, can act on the earth to be opened up.
Als Beispiele seien folgende genannt. silan mischt die Erde mit einer entsprechenden Menge von Magnesiumchlorid, der Endlauge der Kaliwerke, oder mit Chlorammonium und erhitzt das Gemisch entweder durch @änmezufuhr von außen oder durch Einführung von XVasserdampf, wobei die Salzsäure frei wird und die Erde in gewünschtem Sinne beeinflußt. Oder es wird die Erde zum gleichen Zweck mit Kochsalz gemischt und mit Schwefelsäure behandelt. Oder endlich wird die Bleicherde beispielsweise mit Eisenvitriollösung angerührt und die Mischung in langsamem Kreislauf von der Kathode zur Anode elektrolysiert, wobei die wirksame Schwefelsäure in der Nähe der Anode frei auftritt. The following are examples. silan mixes the earth with one corresponding amount of magnesium chloride, the final liquor from the potash works, or with Chlorammonium and heats the mixture either by supplying heat from the outside or by introducing water vapor, whereby the hydrochloric acid is released and the earth in affected in the desired sense. Or it becomes the earth for the same purpose with table salt mixed and treated with sulfuric acid. Or finally the fuller's earth, for example mixed with iron vitriol solution and the mixture in a slow cycle from the Electrolyzed cathode to anode, with the effective sulfuric acid near the Anode occurs freely.
