Description

Verfahren zur Herstellung halogenhaltiger Küpenfarbstoffe In dem zweiten Zusatzpatent 61o 849 wird ein Verfahren zur Herstellung von halogenhaltigen Küpenfarbstoffen beschrieben, das darin besteht, daß man die Küpenfarbstoffe, welche gemäß Patent 52o 876 und dessen Zusatzpatenten 522 970, 525 945 und 541 267 erhalten werden und Acylaminogruppen -enthaltende. - Kondensationsprodukte aus Benzanthronyl-i-aminoanthrachinonen darstellen, gemäß dem Verfahren des Hauptpatents mit chlorierenden Mitteln unter milden Bedingungen behandelt. Gemäß dem Verfahren des ersten Zusatzpatents 6o8 795 werden die gleichen Ausgangskörper zunächst in hochchlorierte Derivate übergeführt und aus diesen durch Chlorwasserstoffabspaltung bzw. Enthalogenierung niedrigchlorierte Farbstoffe gewonnen.Process for the production of halogen-containing vat dyes In the second additional patent 61o 849 a process for the production of halogen-containing vat dyes is described, which consists in that the vat dyes which are obtained according to patent 52o 876 and its additional patents 522 97 0 , 525 945 and 541 267 and Acylamino groups -containing. - represent condensation products of benzanthronyl-i-aminoanthraquinones, treated according to the process of the main patent with chlorinating agents under mild conditions. According to the process of the first additional patent 6o8 795, the same starting bodies are first converted into highly chlorinated derivatives and dyes with low chlorine content are obtained from these by elimination of hydrogen chloride or dehalogenation.

Es wurde nun gefunden, daß man zu ähnlichen wertvollen Farbstoffen gelangt, welche im Vergleich zu den Ausgangskörpern ebenfalls durch eine nach blau verschobene Nuance und verbesserte Chlorechtheit der damit erzielten Färbungen ausgezeichnet sind, wenn man die obigen Ausgangskörper einer Bromierung unter milden Bedingungen unterwirft. Beispiel 25 kg des Farbstoffes, erhalten gemäß Patent 520 876, Beispiel i, werden in fein verteilter Form mit einer Lösung von 16 kg Brom in etwa Zoo kg Eisessig bei Gegenwart von 25 kg Natriumacetat und einer geringen Menge Jod versetzt, und die Mischung wird dann längere Zeit gerührt. Hierauf wird die Reaktionsmasse zum Kochen erhitzt und unter Rückflußkühlung noch etwa 3 Stunden gekocht. Nach Absaugen und Auswaschen wird ein Farbstoff erhalten, der ungefähr i i bis 12 % Brom enthält und der, aus Schwefelsäure gelöst, aus blauvioletter Küpe Baumwolle in echten olivfarbenen Tönen färbt, die wesentlich blauer sind als die des Ausgangsfarbstoffes. Bei starker Einwirkung von Chlorlauge auf -die Färbung ist eine gegenüber dem Ausgangsmaterial verbesserte Chlorechtheit festzustellen. Die Lösungsfarbe in konzentrierter Schwefelsäure ist grün.It has now been found that similar valuable dyes can be obtained which, in comparison to the original bodies, also goes through a to blue The shifted shade and improved chlorine fastness of the dyeings obtained therewith are excellent are, if one of the above starting bodies a bromination under mild conditions subject. Example 25 kg of the dye obtained according to patent 520,876, example i, are finely divided with a solution of 16 kg of bromine in about zoo kg Glacial acetic acid added in the presence of 25 kg of sodium acetate and a small amount of iodine, and the mixture is then stirred for a long time. The reaction mass then becomes heated to a boil and refluxed for about 3 hours. After suction and washing out a dye is obtained which contains about i i to 12% bromine and that, dissolved from sulfuric acid, from blue-violet cotton vat in real olive-colored Colors that are much bluer than that of the original dye. With strong Effect of chlorine lye on -the coloration is opposite to that of the starting material detect improved chlorine fastness. The solution paint in concentrated sulfuric acid is green.

Zu ähnlichen Farbstoffen gelangt man, wenn man die Bromierung nach anderen Methoden durchführt, z. B. durch Einwirkung von Brom in Tetrachloräthan oder Nitrobenzol als Suspensionsmittel mit oder ohne Zusatz von Jod als Katalysator.One arrives at similar dyes if one follows the bromination other methods, e.g. B. by the action of bromine in tetrachloroethane or nitrobenzene as a suspending agent with or without the addition of iodine as a catalyst.
