Description
Verfahren zur Herstellung eines neuen, metallhaltigen Beizenfarbstoifes. Es wurde gefunden, dass@ man einen neuen, kupferhaltigen Beizenfarbstoff erhält, wenn man ein Molekül 2-Amino-5-oxynaphthalin- 7-sulfonsäure zuerst in schwach saurem Me dium mit einem Molekül diazo tierter Amino-4'-ogy-1 :
1'-azo@benzol-3'-carbonsäure- 4-sulfonsäure und nachher in schwach aJka- lischem Medium mit einem Molekül diazotier- ter 2-Amino.-l-ogybenzol-6-carbonsäure-4-sul- fonsäure kuppelt und :den erhaltenen Tris- azofarbstoff mit einer kupferabgebenden Sub stanz behandelt.
<I>Beispiel:</I> 33,7 Teile 3-Amino-4'-ogy-1 : 1'-a,zobenzol- 3' - carbonsäure - 4 - sulfonsäure werden, nach dem aus der schweizerischen Patentschrift Nr. 1750,2.9 bekannten Verfahren diazotiert und in essigsaurer Lösung mit 2'3,9 Teilen 2- Amino-5-ogynaphthalin-7-sulfonsäure gekup pelt.
Dann wird,der erhaltene Disazofarbstoff in alkalischer Lösung mit der Diazoverbin- dung aus 23,3. Teilen 2-Amino-l-ogy-benzol- 6-carbonsäure-4-,sulfonsäure weiter gekuppelt.
Nach beendeter Kupplung wird der erhaltene Trisazo-farbstoff ausgesalzen, abgenutscht, in 20'0O Teilen heissem Wasser gelöst und diese Lösung mit einer wässerigen Lösung von 25 Teilen kristallisiertem Kupfersulfat versetzt. Die rotbraune Fällung wird während einer.
Stunde bei 90 C gerührt und die Ausfäl lung der Kupferverbindung durch Zusatz von Kochsalz beendet. Durch Kochen einer Lösung der Kupferverbindung bei Gegen- wart von Alkali kann, wenn nötig, eventuell nicht komplex gebundenes Kupfer gefällt werden.
Der neue, kupferhaltige Farbstoff bildet, wenn getrocknet, eindunkelbraunes Pulver, löst sich in Wasser mit rotstiehig brauner, in konzentrierter Schwefelsäure mit gelb brauner Farbe und liefert im Chromdruck auf Baumwolle, Kunstseide aus regenerierter Zellulose oder Naturseide rotstichige Braun töne.
Process for the production of a new, metal-containing stain dye. It has been found that a new, copper-containing mordant dye is obtained if a molecule of 2-amino-5-oxynaphthalene-7-sulfonic acid is first added to a weakly acid medium with a molecule of diazotized amino-4'-ogy-1:
1'-azo @ benzene-3'-carboxylic acid-4-sulphonic acid and then in a weakly alkaline medium with a molecule of diazotized 2-amino.-l-ogybenzene-6-carboxylic acid-4-sulphonic acid and: the obtained tris azo dye is treated with a copper-releasing substance.
<I> Example: </I> 33.7 parts of 3-Amino-4'-ogy-1: 1'-a, zobenzene- 3 '- carboxylic acid - 4 - sulfonic acid, according to the Swiss patent no. 1750 , 2.9 known processes and diazotized in acetic acid solution with 2'3.9 parts of 2-amino-5-ogynaphthalene-7-sulfonic acid gekup pelt.
Then the disazo dye obtained is in alkaline solution with the diazo compound from 23.3. Share 2-amino-l-ogy-benzene-6-carboxylic acid-4-, sulfonic acid further coupled.
After the coupling has ended, the trisazo dye obtained is salted out, filtered off with suction, dissolved in 20,000 parts of hot water and this solution is treated with an aqueous solution of 25 parts of crystallized copper sulfate. The red-brown precipitation is during a.
Stirred for an hour at 90 ° C. and the precipitation of the copper compound was terminated by adding sodium chloride. By boiling a solution of the copper compound in the presence of alkali, if necessary, copper that is not complexly bound can be precipitated.
The new, copper-containing dye forms a dark brown powder when dried, dissolves in water with a reddish brown color, in concentrated sulfuric acid with a yellowish brown color and, when printed on chrome on cotton, artificial silk made from regenerated cellulose or natural silk, produces reddish brown tones.
