Description

Verfahren zur Herstellung von chromhaltigen Azofarbstoffen Es wurde gefunden, daß man neue chromhaltige Farbstoffe erhält, wenn man o-Oxyazofarbstoffe, die durch Vereinigung von dianotierten Halogen-a-amino-i-oxybenzolsulfonsäuren mit i-Oxynaphthalin-5-sulfonsäuren entstehen, mit chromabgebenden Mitteln behandelt.Process for the preparation of chromium-containing azo dyes It was found that new chromium-containing dyes are obtained when o-oxyazo dyes, by combining dianotated halogen-a-amino-i-oxybenzenesulfonic acids with i-Oxynaphthalene-5-sulfonic acids are formed when treated with chromium-releasing agents.

Als Diazokomponenten, die für die Herstellung der für das vorliegende Verfahren dienenden Ausgangsstoffe in Betracht kommen, können z. B. die Diazoverbindungen der 4- Clilor-z -amino- i -oxybenzol- 6-sulfonsäure, der G-Chlor-a-amino-i-oxybenzo1-4-sulfonsäure, der 5-Chlor-z-aMino-i-oxybenzol-4-sulfonsäure, der 5-Chlor-a-amino-i-oxybenzol-3-sulfonsäure wie auch diejenigen der entsprechenden Bromderivate verwendet werden.As diazo components that are used for the preparation of the for the present Process serving starting materials can be used, for. B. the diazo compounds 4- Clilor-z -amino- i -oxybenzene- 6-sulfonic acid, G-chloro-a-amino-i-oxybenzo1-4-sulfonic acid, of 5-chloro-z-amino-i-oxybenzene-4-sulfonic acid, of 5-chloro-a-amino-i-oxybenzene-3-sulfonic acid as well as those of the corresponding bromine derivatives can be used.

Die Behandlung mit dem chromabgebenden Mittel kann in saurem, neutralem oder alkalischem Medium, offen oder unter Druck, in Gegenwart oder Abwesenheit von geeigneten Zusätzen, z. B. anorganischen oder organischen Alkalisalzen, durchgeführt werden. Die nach dem vorliegenden Verfahren erhältlichen Chromverbindungen färben Wolle in rotstichigblauen Tönen von guten Echtheitseigenschaften. Sie eignen sich insbesondere zur Herstellung der wertvollen Marineblautöne.The treatment with the chromium donating agent can be in acidic, neutral or alkaline medium, open or under pressure, in the presence or absence of suitable additives, e.g. B. inorganic or organic alkali salts carried out will. Color the chromium compounds obtainable by the present process Wool in reddish blue tones with good fastness properties. You are suitable especially for the production of the valuable navy blue tones.

Beispiel 44#7 Teile des Azofarbstoffes aus dianotierter 4-Chlor-z-arnino-i-oxybenzol-6-sulfonsäure und i-Oxynaphthalin-5-sulfonsäure werden in i6oo Teilen heißem Wasser gelöst, mit 11,4 Teilen Chromoxyd (iooprozentig) in Form einer Chromfluoridlösung versetzt und das Reaktionsgemisch einige Zeit unter Rückflußkühlung gekocht. Die entstandene Chromverbindung wird nach dem Erkalten mit Kochsalz abgeschieden, filtriert, mit ioprozentiger Kochsalzlösung gewaschen und getrocknet. Sie stellt ein violettbraunes Pulver dar, das sich in Wasser, ioprozentiger Sodalösung sowie ioprozentiger Natronlauge mit rötlichvioletter, in konzentrierter Schwefelsäufe mit grüner Farbe löst und Wolle aus schwefelsaurem Bade in blauvioletten Tönen von guten Echtheitseigenschaften färbt.Example 44 # 7 parts of the azo dye from dianotated 4-chloro-z-arnino-i-oxybenzene-6-sulfonic acid and i-oxynaphthalene-5-sulfonic acid are dissolved in 160 parts of hot water with 11.4 parts of chromium oxide (10%) are added in the form of a chromium fluoride solution and the reaction mixture was refluxed for some time. The resulting Chromium compound is deposited after cooling with common salt, filtered, with Washed 10% saline solution and dried. It represents a purple-brown Powder that is in water, 10 percent soda solution and 10 percent sodium hydroxide solution with reddish-purple, in concentrated sulfuric acid with green Color dissolves and wool from sulfuric acid bath in blue-violet tones with good fastness properties colors.

Chromverbindungen mit ähnlichen Eigenschaften werden erhalten, wenn die Chromierung mit andern chromabgebenden Mitteln, z. B. Chromformiat, Chromsulfat, Chromchlorid, durchgeführt wird.Chromium compounds with similar properties are obtained when chroming with other chromium-releasing agents, e.g. B. Chromium formate, chromium sulfate, Chromium chloride.
