den Diazo- inonoazokörper mit 1 Tol l - Amino-2-methoxy- naplithalin-6-sulfonsäure vereinigt, die gebil dete Aminodisazoverbindung weiterdiazotiert, clen Diazodisazokörper mit.
1 hlol 2-Phenyl- amino-5-oxynaphthalin-7-sulfonsäure kuppelt und den entstandenen Trisazofarbstoff durch Behandeln mit einem kupferabgebenden Mit tel in seine hupferkomplexverbindung über führt.
Im nachfolgenden Beispiel bedeuten die Teile Gewichtsteile. Beispiel: 21,7 Teile 2-Amino-l-ca.rboxybenzol-5-siil- ionsäure werden in 400 Teilen Wasser diazo- tiert. Man vereinigt die Diazosuspension mit der natriumcarbonatalkalisehen Lösung von :39,1 Teilen 4-Amino-1-(4'-aeetoacetylamino- benzoyl)-aminobenzol-3-sulfonsäure in 500 Tei len Wasser.
Nachdem die Kupphing vollzogen ist, wird die Aminomonoazoverbinclung abfil- triert und in 400 Teilen Wasser gelöst. Der Lösung werden 6,9 Teile Natriumnitrit zu gegeben und ihr bei einer Temperatur von 10 25 Teile konzentrierte Salzsäure zugetropft. Wenn die Diazotierung beendigt ist, was nach 2 bis 4 Stunden der Fall ist, wird der Diazo- suspension eine Lösung aus 27,
5 Teilen des Natriumsalzes der 1-Amino-2-methoxynaph- thalin-6-sulfonsäure in 400 Teilen Wasser zu gefügt und in der Masse durch Zustreuen von kristallisiertem Natriumacetat ein pH-Wert von 3,5 bis 4 eingestellt. Nach Beendigung der Kupplung wird die Kupplungslösung alkalisch gestellt.
Man isoliert die Aminodisazoverbin- dung, rührt sie wieder in 1000 Teilen Wasser an und trägt die Suspension nach Zugabe von 7 Teilen Natriumnitrit, bei 10 , in 30 Teile konzentrierte Salzsäure und 200 Teile Eis ein. Die Diäzodisazoverbindung wird abfiltriert und in Form einer Paste bei 10 in eine Lö sung aus 33,7 Teilen des Natriumsalzes der 2-Phenylamino-5-oxynaphthalin-7-sulfonsäure, 300 Teilen Wasser und 200 Teilen Pyridin eingetragen.
Der gebildete Trisazofarbstoff wird abgeschieden und abfiltriert.
Zur Überführung in seine Kupferkom- plexverbindung wird die feuchte Farbstoff paste bei 80-90 in eine Schmelze von 350 Teilen kristallisiertem Natriumacetat, 50 Tei len kristallisiertem Kupfersulfat und 100 Tei len Wasser eingetragen. Man rührt die Schmelze während 4 Stunden bei 90 und kocht sie dann während 6 Stunden am Rück fluss. Der gebildete kupferhaltige Trisazofarb- stoff wird hierauf isoliert und getrocknet.
Er ist ein dunkles Pulver, das sich in Was ser mit grüner Farbe löst und Fasern aus Zellulose in grünen Tönen von hervorragen der Licht- und Waschechtheit färbt.
Process for the production of a copper-containing trisazo dye. The present patent relates to a ver for the production of a copper-containing trisazo dye, which consists in that 1.
Mol of the diazo compound of 2-amino-1.-earboxvbenzene-5-sulfonic acid combined with 1 mole of 4- nino-1- (4'-acetoacetyla.minobenzoy 1) -amino-lierizol-3-sulfonic acid, the amino-nionoa7o-compound diazotized,
the diazo inonoazo body combined with 1 tol l -amino-2-methoxynaplithalin-6-sulfonic acid, the aminodisazo compound formed further diazotized, the diazodisazo body with.
1 hlol of 2-phenylamino-5-oxynaphthalene-7-sulfonic acid couples and converts the resulting trisazo dye into its copper complex compound by treating it with a copper-releasing agent.
In the following example, the parts are parts by weight. Example: 21.7 parts of 2-amino-1-approximatelyrboxybenzene-5-silicic acid are diazotized in 400 parts of water. The diazo suspension is combined with the sodium carbonate alkali solution of: 39.1 parts of 4-amino-1- (4'-aeetoacetylamino-benzoyl) -aminobenzene-3-sulfonic acid in 500 parts of water.
After the Kupphing has taken place, the Aminomonoazoverbinclung is filtered off and dissolved in 400 parts of water. 6.9 parts of sodium nitrite are added to the solution and concentrated hydrochloric acid is added dropwise at a temperature of 10-25 parts. When the diazotization has ended, which is the case after 2 to 4 hours, the diazotization becomes a solution of 27,
5 parts of the sodium salt of 1-amino-2-methoxynaphthalene-6-sulfonic acid in 400 parts of water were added and a pH of 3.5 to 4 was set in the mass by sprinkling with crystallized sodium acetate. After the coupling has ended, the coupling solution is made alkaline.
The aminodisazo compound is isolated, stirred again in 1000 parts of water and, after the addition of 7 parts of sodium nitrite, at 10, in 30 parts of concentrated hydrochloric acid and 200 parts of ice, the suspension is introduced. The diazodisazo compound is filtered off and entered in the form of a paste at 10 in a solution of 33.7 parts of the sodium salt of 2-phenylamino-5-oxynaphthalene-7-sulfonic acid, 300 parts of water and 200 parts of pyridine.
The trisazo dye formed is deposited and filtered off.
To convert it into its copper complex compound, the moist dye paste is added at 80-90 to a melt of 350 parts of crystallized sodium acetate, 50 parts of crystallized copper sulfate and 100 parts of water. The melt is stirred for 4 hours at 90 and then refluxed for 6 hours. The copper-containing trisazo dye formed is then isolated and dried.
It is a dark powder that dissolves in water with a green color and colors cellulose fibers in green shades of excellent lightfastness and washfastness.
