Description
Verfahren zur Herstellung eines chromhaltigen Azofarbstoffes. Es wurde gefunden, dass ein chromhaltiger Azofarbstoff hergestellt werden kann, wenn ein Azofarbstoff der Formel
EMI0001.0005
worin R einen beliebigen abspaltbaren, orga nischen Rest bedeutet, durch Behandlung mit verseifenden Mitteln in den entsprechen den o, o'-Oxyazofarbstoff übergeführt und dieser mit chromabgebenden Mitteln behandelt wird.
Der neue chromhaltige Farbstoff ist ein braunrotes Pulver, das sich in Wasser, sowie in verdünnter Sodalösung mit bordeauxroter Farbe löst und Wolle aus saurem Bade in sehr gleichmässigen und ausgezeichnet licht echten, bordeauxroten Tönen färbt.
Die dem Verfahren als Ausgangsstoffe dienenden Azofarbstoffe der obigen Formel können durch Kuppeln der dianotierten 2- Amino-l-phenoläther und -ester, die in 4-Stel- lung eine Sulfamidgruppe enthalten, mit 2 Oxynaphthalin-6.8-disulfonsäure in alkali-, schem Medium erhalten werden. Aus diesen kann man durch Einwirkung verseifender Mittel den o, o'-Oxyazofarbstoff herstellen und diesen mit chromabgebenden Mitteln behandeln.
Die Überführung dieses Azofarbstoffes in die komplexe Chromverbindung wird nach beliebigen Verfahren ausgeführt. Als chrom abgebende Mittel eignen sich beispielsweise Chromsulfat, Chromformiat und Alkalichro- mite. Die Überführung kann mit oder ohne geeignete Zusätze, wie z. B. Kochsalz, Salze organischer Säuren, freie Säuren, in Gegen wart oder in Abwesenheit von organischen Lösungs- bezw. Verteilungsmitteln, wie z. B. Alkohol, Glyzerin oder Pyridin, offen oder unter Druck erfolgen.
Eine besondere Ausführungsform des vor liegenden Verfahrens besteht darin, dass ein dem vorliegenden Verfahren als Ausgangs stoff dienender Azofarbstoff der obigen Formel nach beliebigen Verfahren unter solchen Be dingungen mit chromabgebenden Mitteln be handelt wird, dass Verseifung und Bildung der komplexen Chromverbindung unmittelbar nacheinander eintreten.
<I>Beispiel 1:</I> 34,2 Teile 1-(4'-Methylberrzol-1'-sulfo-)- oxy-2-aminobenzol-4-sulforrsäureamid werden dianotiert und mit 32 Teilen 2-Oxyrraphthalin- 6.8-disulfonsäure in sodaalkaliseher Lösung gekuppelt. Durch Zugabe von Natronlauge und Erwärmen wird darauf der p-Toluol- sulfonsäurerest abgespalten und der erhaltene o-Oxyazofarbstoff durch Ansäuern und Bei gabe von Kochsalz abgeschieden.
Der ab filtrierte Farbstoff wird mit 400 Teilen Wasser und 100 Teilen einer 8,4 Teile Chromoxyd enthaltenden Chromsrrlfatlösung längere Zeit unter Rühren und Rückfluss zum Sieden erhitzt und die erhaltene Chromver bindung durch Kochsalzzusatz und Abkühlen lassen abgeschieden, dann abfiltriert und getrocknet.
<I>Beispiel 2:</I> 56 Teile des Farbstoffes aus dianotiertem 1-Methoxy-2-aminobenzol-4-sulfamid und 2 Oxynaphthalin-6.8-disrrlforrsäure werden im Autoklaven mit 300 Teilen Wasser und 100 Teilen einer 8,4 Teile Chromoxyd enthalten den Chromsulfatlösung 5 Stunden auf 130 bis 135 erhitzt. Die Lösung wird nachher auf etwa 150 Raumteile eingeengt und der Farbstoff durch Kochsalzzugabe abgeschieden, abfiltriert und getrocknet. Die erhaltene Chromverbindung stimmt mit dem nach Bei spiel 1 hergestellten Chromkomplex überein.
Zu derselben komplexen Chromverbindung gelangt man auch, wenn man den Farbstoff aus dianotiertem 1-(4'-Methylbenzol-1'-sulfo-)- oxy-2-amirroberrzol-4-sulfamid und 2-Oxy- naphthalirr-6.8-disulforrsäure in derselben \'eise mit chromabgebenden Mitteln behan delt.
Process for the preparation of a chromium-containing azo dye. It has been found that a chromium-containing azo dye can be prepared when an azo dye of the formula
EMI0001.0005
where R denotes any removable, organic radical, converted by treatment with saponifying agents into the corresponding o, o'-oxyazo dye and this is treated with chromium donating agents.
The new chromium-containing dye is a brown-red powder that dissolves in water and in dilute soda solution with a burgundy color and dyes wool from an acid bath in very even and extremely light, burgundy-red tones.
The azo dyes of the above formula which are used as starting materials for the process can be prepared by coupling the dianotated 2-amino-1-phenol ethers and esters, which contain a sulfamide group in the 4-position, with 2 oxynaphthalene-6.8-disulfonic acid in an alkaline medium can be obtained. The o, o'-oxyazo dye can be produced from these by the action of saponifying agents and treated with chromium-releasing agents.
The conversion of this azo dye into the complex chromium compound is carried out by any method. Chromium sulfate, chromium formate and alkali chromites are suitable as chromium-releasing agents. The transfer can with or without suitable additives, such as. B. table salt, salts of organic acids, free acids, in the presence or in the absence of organic solutions or. Distribution means, such as B. alcohol, glycerine or pyridine, open or under pressure.
A particular embodiment of the present process consists in that an azo dye of the above formula serving as starting material for the present process is treated with chromium-releasing agents by any process under such conditions that saponification and formation of the complex chromium compound occur immediately one after the other.
<I> Example 1: </I> 34.2 parts of 1- (4'-methylberrzene-1'-sulfo -) - oxy-2-aminobenzene-4-sulforric acid amide are dianotized and mixed with 32 parts of 2-oxyrraphthalene-6.8- disulfonic acid coupled in a soda-alkaline solution. The p-toluenesulfonic acid residue is then split off by adding sodium hydroxide solution and heating, and the o-oxyazo dye obtained is deposited by acidification and addition of common salt.
The filtered dye is heated to boiling with 400 parts of water and 100 parts of a chromium oxide containing 8.4 parts of chromium oxide for a long time with stirring and reflux and the chromium compound obtained is deposited by adding sodium chloride and allowing it to cool, then filtered off and dried.
<I> Example 2: </I> 56 parts of the dye made from dianotized 1-methoxy-2-aminobenzene-4-sulfamide and 2-oxynaphthalene-6.8-disrrlforrsic acid are mixed with 300 parts of water and 100 parts of 8.4 parts of chromium oxide in an autoclave contain the chromium sulfate solution heated to 130 to 135 hours for 5 hours. The solution is then concentrated to about 150 parts by volume and the dye is deposited by adding sodium chloride, filtered off and dried. The chromium compound obtained agrees with the chromium complex prepared according to Example 1.
The same complex chromium compound can also be obtained if the dye of dianotated 1- (4'-methylbenzene-1'-sulfo -) - oxy-2-amirroberrzene-4-sulfamide and 2-oxynaphthalir-6.8-disulforric acid are used in the same \ 'iron treated with chromium-releasing agents.
