Description

Verfahren zur hydrolytischen Spaltung von sauren Titansulfatlösungen Bei der hydrolytischen Spaltung von sauren Titansulfatlösungen bei höheren Temperaturen unter Druck kann die Ausscheidung der Titansäure aus den Lösungen durch den Zusatz einer gewissen Titansäuremenge, die man bei einem vorangegangenen Arbeitsgang gewonnen hat, beschleunigt werden. Die Anwesenheit von Titansäure hat auch noch den Vorteil, daß das Produkt bei den verschiedenen einzelnen Druckspaltungen gleichmäßiger ausfällt, gut kristallin ist und daher besser und leichter zu wertvollen Titanpigmenten verarbeitet werden kann.Process for the hydrolytic cleavage of acidic titanium sulphate solutions During the hydrolytic cleavage of acidic titanium sulphate solutions at higher temperatures under pressure, the titanic acid can be eliminated from the solutions by the addition a certain amount of titanium acid obtained in a previous operation has to be accelerated. The presence of titanic acid also has the advantage that the product turns out to be more even with the various individual pressure gaps, is well crystalline and therefore processed better and more easily into valuable titanium pigments can be.

Man hat bereits vorgeschlagen, die hydrolytische Spaltung schwefelsaurer Titanlösungen bei Gegenwart fein gemahlener fertiger Titansäure durchzuführen, um die Poren des letzteren mit dem beim Erhitzen der Mischung ausfallenden Titandioxyd zu verschließen. Von diesem bekannten Verfahren unterscheidet sich die einen ganz anderen Zweck verfolgende vorliegende Erfindung zunächst durch die Verwendung einer gefällten und nicht weiterbehandelten Titansäure und ferner durch das Mengenverhältnis zwischen der zugesetzten und der auszufällenden Titansäure insofern, als bei dem vorliegenden Verfahren die zugesetzte Titansäuremenge ganz erheblich geringer ist als bei dem obenerwähnten Verfahren.It has already been proposed that the hydrolytic cleavage of sulfuric acid Titanium solutions in the presence of finely ground finished titanic acid to carry out the pores of the latter with the titanium dioxide precipitated when the mixture is heated to close. One of them is completely different from this known method The present invention pursues another purpose initially through the use of a precipitated and untreated titanic acid and also by the quantitative ratio between the added and the titanic acid to be precipitated insofar as in the case of present process, the amount of titanium acid added is considerably lower than the above-mentioned method.

Man verfährt am zweckmäßigsten so, daß man einen kleinen Teil des Autoklaveninhaltes einer vorhergehenden Spaltung in dem Autoklaven zurückläßt, ihn mit neuer Titanlösung fällt und die neue Spaltung mit diesem Gemisch durchführt. Es genügt, etwa i bis io% des Autoklaveninhaltes zurückzulassen, um den günstigeren Verlauf der Spaltung zu erzielen.It is most expedient to proceed in such a way that a small part of the Leaves autoclave contents of a previous cleavage in the autoclave, him falls with new titanium solution and carries out the new cleavage with this mixture. It is sufficient to leave about i to io% of the contents of the autoclave in order to get the cheaper one To achieve the course of the split.
