Description

Herstellung von Kryolith Vorliegendes Verfahren betrifft die Herstellung von Kryolithen durch Umsetzen von Aluminiumnitraten und Metallfluorid. Man läßt die betreffenden Verbindungen in wäßrigen Lösungen oder wäßrigen Suspensionen, zweckmäßig in der Wärme und unter Bewegung (Rühren), aufeinander einwirken, wobei nach einiger Zeit :die entsprechenden Krvolithe in sehr reiner Form entstehen unter Bildung derjenigen Metallnitrate, deren Metallfluoride zum Umsetzen verwendet wurden.Manufacture of Cryolite The present process relates to manufacture of cryolites by reacting aluminum nitrates and metal fluoride. One lets the compounds in question in aqueous solutions or aqueous suspensions, expedient in the warmth and with movement (stirring), act on each other, after some Time: the corresponding Krvolithe arise in a very pure form with the formation of those Metal nitrates, the metal fluorides of which were used for the reaction.

So wird Aluminiumnitrat z. B. mit Natriumfluorid, mit Kaliumfluorid, mit Ammoniumf.iuorid usw. umgesetzt.So aluminum nitrate z. B. with sodium fluoride, with potassium fluoride, implemented with Ammoniumf.iuorid etc.

Da das Aluminiumnitrat bekanntlich Kristallwasser enthält, so kann man die Komponenten, nachdem man sie vorher zweckmäßig innig gemischt hat, durch Erhitzen innerhalb weiter Temperaturgrenzen aufeinanderwirken lassen, wobei ebenfalls die entsprechenden Kry olithe entstehen.As aluminum nitrate is known to contain water of crystallization, so can the components, after they have been appropriately intimately mixed beforehand Allow heating to interact within wide temperature limits, whereby likewise the corresponding cryoliths arise.

Überhaupt kommt für das vorliegende Kryolithherstellungsverfahren Erwärmen, Rühren oder sonstige mechanische Bearbeitung, ferner Druckwirkung als fördernd in Frage. Man kann auch mit ganz wenig Flüssigkeit und sogar festen Stoffen arbeiten.Anyway, comes for the present cryolite manufacturing process Heating, stirring or other mechanical processing, as well as pressure effect as supportive in question. You can also use very little liquid and even solid matter work.
