Verfahren zur Herstellung von Bromierungsprodukten mehrfach halogenierter Indigos.
Gegenstand der Patentschrift Nr. 48682 ist ein Verfahren zur Herstellung von Bromierungsprodukten mehrfach halogenierter Indigos, die als Perbromide mindestens tetrahatogemerter Indigos aufzufassen sind.
Das Verfahren lässt sich, wie weiter gefunden wurde, auch auf die Monohalogen- substitutionsprodukte, insbesondere auch auf das monochlorierte Produkt, welches man gemäss D. R. Patentschrift Nr. 168683 aus Indigo bzw. Indigweiss und Sulfurylchlorid durch vorsichtige Chlorierung erhält, anwenden.
Das Verfahren ist das des Stammpatentes. Es werden z. B. 10 Teile des monochlorierten Produkts des D. R. P. Nr. 168683 mit 50 Teilen Brom einige Stunden auf dem Wasserbade auf etwa 40 bis 600 oder auch auf Temperaturen über 1000 unter Druck erwärmt.
Der so z. B. bei 40 bis 60 gewonnene Farbstoff kann durch Wasch n mit Tetrachlorkohlenstoff oder durch erwärmen im trockenen Luftstrom von überschüssigem Brom befreit worden. Er stellt ein grünschwarles Pulver dar, mit einem Gehalt von 59#9% Gesamtbrom, : 3@ Chlor, 22'60'' mit Jodnatrium bestimmbares Brom dar, welches sich in konzentrierter Schwefelsaure mit grünlichblauer Farbe löst, beim Erwärmen mit Wasser halogenierte Isatine Hefert, in der Hydrosultitküpe Baumwolle und Wolle in schönen blauen Tönen färl) t.
EMI1.1
Produkt ein blauer Farbstoff, der als ein Chlortribromindigo aufzufassen sein dürfte.
Erhitzt man auf über 100 , z. B. unter Druck, so erhält man noch etwas höher bromierte Produkte.

Process for the production of bromination products of multiply halogenated indigos.
The subject of patent specification No. 48682 is a process for the preparation of bromination products of multiply halogenated indigos, which are to be understood as perbromides of at least tetrahatogenous indigos.
As has also been found, the process can also be applied to the monohalogen substitution products, in particular also to the monochlorinated product which is obtained from indigo or indigo white and sulfuryl chloride by careful chlorination according to D. R. Patent No. 168683.
The procedure is that of the parent patent. There are z. B. 10 parts of the monochlorinated product of the D.R.P. No. 168683 with 50 parts of bromine heated under pressure for a few hours on the water bath to about 40 to 600 or to temperatures above 1000.
The so z. B. at 40 to 60 obtained dye can be freed from excess bromine by washing with carbon tetrachloride or by heating in a dry air stream. It is a greenish powder, with a content of 59 # 9% total bromine,: 3 @ chlorine, 22'60 '' with sodium iodine determinable bromine, which dissolves in concentrated sulfuric acid with greenish-blue color, when heated with water halogenated isatine yeast , in the Hydrosultitküpe cotton and wool in beautiful blue tones.
EMI1.1
Product is a blue dye that should be interpreted as a chlorotribromoindigo.
If it is heated to over 100, e.g. B. under pressure, you get slightly higher brominated products.
