Description

Verfahren zur Herstellung von Erdalkalichloriden. Die zur Zeit gebräuchlichen Verfahren zur Darstellung von Erdalkalichloriden, wie Barium- und Kalziumchlorid, beruhen auf der Zersetzung von Erdalkalikarbonaten oder -sulfiden mittels .Salzsäure. Die Herstellung von Bariumchlorid durch Umsetzung von Erdalkalikarbonaten mit Magnesiumchlöridlösungen ist zwar bereits bekannt, doch führen diese bekannten Verfahren teils nur zu ungenügenden Ausbeuten, teils erfordern sie so umständliche und kostspielige Operationen, daß sie in die Technik nicht Eingang finden konnten.Process for the production of alkaline earth chlorides. The currently used Process for the preparation of alkaline earth chlorides, such as barium and calcium chloride, are based on the decomposition of alkaline earth carbonates or sulfides by means of hydrochloric acid. The production of barium chloride by reacting alkaline earth carbonates with magnesium chloride solutions is already known, but some of these known methods are unsatisfactory Yields, in part, they require operations so cumbersome and costly that they could not find their way into technology.

Es hat sich nun gezeigt, daß man unter Anwendung von Magnesiumchlorid auf einfache Weise zu reinen Erdalkalichloriden gelangen kann, wenn man natürliche oder künstliche Erdalkalikarbonate mit festem Chlormagnesium entweder in Form der Hydrate oder im wasserfreien Zustand erhitzt.It has now been shown that using magnesium chloride pure alkaline earth chlorides can easily be obtained if natural or artificial alkaline earth carbonates with solid magnesium chloride either in the form of the Hydrates or heated in the anhydrous state.

So kann man beispielsweise durch Erhitzen eines Gemisches von ;äquimolekularen Mengen gefällten Bariumkarbonats und Magnesiumchlorhexahydrats auf 36o° bereits über 9o Prozent des Bariums in Bariumchlorid umwandeln und gegebenenfalls hierbei die Umsetzung durch Anwendung eines Magnesiumchloridhexahydratüberschusses zu einer nahezu quantitativen gestalten.For example, by heating a mixture of equimolecular Quantities of precipitated barium carbonate and magnesium chlorhexahydrate at 36o ° already convert over 90 percent of the barium into barium chloride and, if necessary, at the same time the implementation by using an excess of magnesium chloride hexahydrate to one almost quantitative design.

In gleicher Weise erhält man aus gefälltem Kalziumkarbonat durch Erhitzen mit der äquimolekularen Menge Magnesiumchloridhexahydrat auf Temperaturen zwischen ¢0o und 5oo° vollständige Umsetzung zu Kalziumchlorid.In the same way, precipitated calcium carbonate is obtained by heating with the equimolecular amount of magnesium chloride hexahydrate to temperatures between ¢ 0o and 5oo ° complete conversion to calcium chloride.

Die vorliegende Erfindung gestattet es, auch aus natürlichen Erdalkalikarbonaten reines Erdalkalichlorid mit fast quantitativer Ausbeute herzustellen, nur muß in diesem Falle die Mischung mit Chlormagnesium auf höhere Temperatur erhitzt werden.The present invention allows also from natural alkaline earth carbonates to produce pure alkaline earth chloride with almost quantitative yield, only in In this case the mixture can be heated to a higher temperature with magnesium chloride.
