Description

Verfahren zur Herstellung von Erdalkalichloriden. Die Chloride der Erdalkalien werden im allgemeinen aus den Carbonaten oder Sulfiden mittels Salzsäure 'hergestellt.Process for the production of alkaline earth chlorides. The chlorides of Alkaline earths are generally made from the carbonates or sulfides using hydrochloric acid 'manufactured.

Es hat sich nun gezeigt, daß sich die Erdalkalichloride aus den- Sulfaten in einfacher Weise unmittelbar in einem Arbeitsgang herstellen lassen, wenn man diese mit Kohlenoxyd oder kohlenoxydhaltigen Gasen unter Zusatz von Chlor oder Chlorwasserstoff behandelt. Dabei kann man schon bei vergleichsweise niederer Temperatur Erdalkalichlorid in guter Ausbeute erhalten.It has now been shown that the alkaline earth chlorides are derived from the sulfates can be produced in a simple manner directly in one operation, if one these with carbon dioxide or gases containing carbon dioxide with the addition of chlorine or hydrogen chloride treated. You can use alkaline earth chloride even at a comparatively low temperature obtained in good yield.

Man hat bereits die Chloride der Erdalkalien aus ihren Sulfaten dadurch gewonnen, daß man durch ein Gemenge des zu reduzierenden Minerals mit Kohle und anderen Substanzen während des Glühens einen Strom von Salzsäuredämpfen leitet. Bei diesem Verfahren ist es erforderlich, das Material fein zu zermahlen, und das Endprodukt ist stark durch Kohle und Asche verunreinigt. Im vorliegenden Falle ist dagegen eine besonders feine Zerteilung des Ausgangsmaterials nicht erforderlich; man kann dieses beispielsweise in faustgroßen Stücken verwenden. Ferner wird hierbei unmittelbar ein Produkt von großer Reinheit erzielt.One has already got the chlorides of the alkaline earths from their sulphates won that one by a mixture of the mineral to be reduced with coal and conducts a stream of hydrochloric acid vapors to other substances while it is glowing. In this process, it is necessary to grind the material finely, and that End product is heavily contaminated with coal and ash. In the present case is on the other hand, a particularly fine division of the starting material is not necessary; you can use this in fist-sized pieces, for example. Furthermore, here immediately obtained a product of great purity.

Beispiel. Schwerspat wird unter Überleiten von Wassergas, dem Chlor beigefügt ist, auf etwa 8oo° erhitzt; man erhält ein Produkt, das in Wasser zu etwa 95 Prozent löslich ist. Das aus der wäßrigen Lösung erhaltene Salz ist reines Chlorbarium.Example. Barite becomes chlorine when water gas is passed over it is attached, heated to about 8oo °; one obtains a product that is roughly in water 95 percent is soluble. The salt obtained from the aqueous solution is pure chlorobarium.
