Wird Indigo in der Wärme aus alkalischen Indigoleukolösungen mit Luft ausgeblasen, so hat er die Neigung, in fein kristallinischer Form auszufallen, was in manchen Fällen für seine direkte Verwendung ein Nachteil ist. Um ein derartiges Produkt z. B. für die Verwendung in der Gärungsküpe brauchbar zu machen, muß der Farbstoff zunächst durch eine Nachbehandlung, etwa gemäß dem Verfahren des Patents 121450 durch Behandlung mit Schwefelsäure und Wiederzersetzung des entstandenen Sulfats, in eine geeignete Form übergeführt werden.If indigo is blown out of alkaline indigoleuco solutions with air in the warmth, so it has a tendency to precipitate in a finely crystalline form, which in some cases is a disadvantage for its direct use. To such a product z. B. for the To make it useful in the fermentation vat, the dye must first pass through post-treatment, for example in accordance with the method of patent 121450 by treatment with sulfuric acid and re-decomposition of the resulting sulfate into a suitable form be transferred.

!5 zu einem äußerst fein verteilten, für alle Zwecke verwendbaren Produkt gelangt, wenn man den alkalischen Lösungen der Indigoleukoverbindungen vor dem Ausblasen geringe Mengen gesättigter oder ungesättigter Fettsäuren oder Harzsäuren oder ihrer alkalilöslichen Salze zusetzt, so daß die Oxydation in Anwesenheit irgend einer Seife vor sich geht. Dieser Zusatz führt auch noch den Vorteil mit sich, daß die Oxydation der Indigoleukoverbindung wesentlich rascher erfolgt als bei der üblichen Arbeitsweise.! 5 to an extremely finely divided, for everyone Purpose usable product arrives when one of the alkaline solutions of the indigoleukoverbindungen before blowing out small amounts of saturated or unsaturated fatty acids or resin acids or their alkali-soluble ones Adds salts, so that the oxidation takes place in the presence of some kind of soap. This addition also leads to the This has the advantage that the oxidation of the indigoleuco compound takes place much more quickly than in the usual way of working.
Eine Lösung von 100 Teilen Indoxylsäure in 2500 Teilen Wasser und der erforderlichen Menge Natronlauge wird mit einer Lösung von 10 Teilen Schmierseife versetzt und kochend heiß durch einen Luftstrom oxydiert. A solution of 100 parts of indoxylic acid in 2500 parts of water and the required Amount of sodium hydroxide solution is mixed with a solution of 10 parts of soft soap and oxidized by a stream of air while boiling hot.
An Stelle der Schmierseife kann mit demselben Erfolg jedes andere Alkalisalz der Fettsäure- oder ölsäurereihe oder einer Harzsäure verwendet werden, z. B. der Palmitinsäure, Leinölsäure, Erukasäure, Rizinusölsäure usw.Instead of soft soap, any other alkali salt can be used with the same success Fatty acid or oleic acid series or a resin acid can be used, e.g. B. palmitic acid, Linseed oleic acid, erucic acid, castor oleic acid, etc.
Eine Lösung von 100 Teilen Indigweiß in der nötigen Menge Alkali und 7000 Teilen Wasser wird unter Zusatz von 30 Teilen Türkischrotöl, gelöst in Wasser, durch einen kräftigen Luftstrom kalt ausgeblasen. Der erhaltene Indigo ist in derartig feiner Verteilung, daß er durch die Filter geht und erst nach Art des kolloidalen Indigos durch Zusatz von Kochsalz gefällt und filtrierfähig gemacht werden muß.A solution of 100 parts of indigo white in the required amount of alkali and 7000 parts Water is with the addition of 30 parts of Turkish red oil, dissolved in water, through a strong air stream blown out cold. The indigo obtained is so finely divided, that it goes through the filters and only through the manner of the colloidal indigo The addition of table salt has to be precipitated and made filterable.
