Description
Verfahren zur Gewinnung von Salzen durch Einwirkung konzentrierter Lösungen " verschiedener Salze aufeinander. Man kann Salze in fester Form dadurch gewinnen, daß man sie mit Lösungen eines anderen Salzes zusammenbringt, welches, ohne eine chemischeUmsetzungherbeizuführen,aussalzend wirkt, Es ist bekannt, daß aus konzentrierten Chlornatriumlösumgen durch konzentrierte Lösungen von Chlorkalzium, Chlormagnesium (z. B. Endlaugen der Chlorkaliumfabrikation) Kochsalz auf kaltem Wege ausgefällt wird. Man erhält durch das geschilderte Verfahren Salz voluminöser Beschaffenheit und gleichmäßiger Körnung, welches als Speisesalz zu verwenden ist und durch Vermischung mit rohem gemahlenen Steinsalz eine Auflockerung des letzteren bewirkt. Man kann auch beispielsweise eine Chloridlösung und eine Sulfatlösung aufeinander wirken lassen, z. B. Chlornatrium und Magnesiumsulfat.Process for the extraction of salts by the action of concentrated Solutions "of different salts on top of each other. One can get salts in solid form thereby win by bringing them together with solutions of another salt which, without causing a chemical reaction, acts salting out, It is known that from concentrated sodium chloride solutions through concentrated calcium chloride solutions, Magnesium chlorine (e.g. final lyes from the potassium chlorine production) table salt on cold Ways is failed. The process described gives more voluminous salt Consistency and uniform grain, which is to be used as table salt and by mixing with raw, ground rock salt, the latter is loosened causes. You can also, for example, a chloride solution and a sulfate solution on top of each other let it work, z. B. sodium chloride and magnesium sulfate.
Die Einwirkung der Salzlösungen, z. B. Chlormagnesium oderChlorkalzium auf Chlornatriumlösungen, erfolgte bisher derartig, daß man die Lösungen direkt zueinander gab. Man erhält hierbei kleine gleichmäßige einzelne Körnchen, deren Größe und Beschaffenheit wohl von der Art der Vermischung der Lösungen abhängt und hierdurch beeinflußt wird, aber nicht beliebig geregelt werden kann. Das vorliegende Verfahren bezweckt eine Regelung der Korngröße des gefällten Salzes, z. B. des Chlornatriums, so daß man nach Belieben größere oder kleinere Körner erhalten kann. Das gewonnene Salz kann die gleiche Beschaffenheit wie das im Siedesalzbetriebe gewonnene Kochsalz haben. Das Verfahren besteht darin, daß man die gesättigten Lösungen der aufeinander wirkenden Salze von Kochsalz einerseits und Chlormagnesium (Chlorkalzium, Endlauge o. dgl.) anderseits in durch eine poröse Scheidewand getrennte Abteilungen bringt und die Lösungen durch die durchlässige oder halbdurchlässige Scheidewand zueinandertreten läßt. Man kann eine tierische Membran, poröse Tonzellen o. dgl. als Scheidewand verwenden. Je nach dem Grade der Durchlässigkeit der Scheidewand kann man verschieden große Salzkörner erhalten. Das Verfahren kann bei gewöhnlicher Temperatur oder auch in der Wärme bei gewöhnlichem Atmosphärendruck oder bei vermindertem oder erhöhten Druck ausgeführt werden. Man kann beispielsweise die eine Abteilung unter verminderten oder erhöhten Druck setzen.The action of the salt solutions, e.g. B. chlorine magnesium or calcium chloride on sodium chloride solutions, so far has been done in such a way that the solutions are directly gave to each other. In this way, small, uniform, individual grains are obtained Size and quality probably depends on the type of mixing of the solutions and is influenced by this, but cannot be regulated at will. The present The purpose of the method is to regulate the grain size of the precipitated salt, e.g. B. of sodium chloride, so that you can get larger or smaller grains at will. The won Salt can have the same properties as the table salt obtained in vacuum salt factories to have. The procedure consists in that one of the saturated solutions of each other acting salts of common salt on the one hand and chlorine magnesium (chlorine calcium, final lye o. the like) on the other hand into compartments separated by a porous partition and the solutions come together through the permeable or semi-permeable septum leaves. An animal membrane, porous clay cells or the like can be used as a partition use. Depending on degree of permeability of a partition it is possible to differ get large grains of salt. The procedure can be at ordinary temperature or also in the heat at ordinary atmospheric pressure or at reduced or increased Printing. One can, for example, the one department under diminished or put increased pressure.
