Description

Verfahren zur Darstellung von o-Oxyazofarbstoffen. Es wurde gefunden, daß durch Kupplung von o-Oxydiazoverbindungen der Benzol-oder Naphthalinreihe mit 8-Oxychinolin oder 8-Oxychinolin-5-sulfosäure sich wertvolle Beizenfarbstoffe gewinnen lassen, deren Färbungen durch ihre Wasch-, Walk- und Lichtechtheit ausgezeichnet sind und hierin die analogen Farbstoffe aus Oxyverbindungen der Benzol- oder Naphthalinreihe in der Regel übertreffen.Process for the preparation of o-oxyazo dyes. It was found, that by coupling o-oxydiazo compounds of the benzene or naphthalene series with 8-oxyquinoline or 8-oxyquinoline-5-sulfonic acid can win valuable stain dyes let whose colorations are distinguished by their wash, milled and lightfastness are and herein the analogous dyes from oxy compounds of the benzene or naphthalene series usually outperform.

B e i s p i e 1 1. Man diazotiert 18 # 9 Teile 2-Amino-i-oxybenzol-q.-sulfosäure in der üblichen Weise und läßt die Diazoverbindung in eine ätzalkalische Lösung von 1q. # 5 Teilen 8-Oxychinolin einlaufen. Nach beendeter Kupplung salzt man den Farbstoff aus und arbeitet ihn wie gewöhnlich auf. Er färbt Wolle braun; durch Nachchromieren erhält man ein sehr licht- und walkechtes Bordeaux.EXAMPLE 1 1. 18 # 9 parts of 2-amino-i-oxybenzene-q-sulfonic acid are diazotized in the usual way and leaves the diazo compound in a caustic solution from 1q. # 5 Share 8-oxyquinoline. After the coupling is complete, the salt is added Dye and work it up as usual. He dyes wool brown; by re-chrome plating you get a very lightfast and whalefast Bordeaux.

Ähnliche Farbstoffe, deren direkte Färbungen braun und deren Chromlacke bordeauxrot sind, erhält man unter anderem, wenn man von q.-Nitro-2-amino-i-oxybenzol-6-sulfosäure oder ¢-Chlor-2-amino-i-oxybenzol-5-sulfosäure ausgeht.Similar dyes, their direct coloration brown and their chrome lacquers are burgundy red, is obtained, among other things, if one of q.-nitro-2-amino-i-oxybenzene-6-sulfonic acid or [-chloro-2-amino-i-oxybenzene-5-sulfonic acid starts out.

B e i s p i e 1 2. i9 # 9 Teile q. # 6-Dinitro-2-amino-i-oxybenzol werden in der üblichen Weise diazotiert und mit einer sodaalkalischen Lösung von 22 # 5 Teilen 8-Oxychinolin-5-sulfosäure vereinigt. Der abgeschiedene Farbstoff färbt auf Wolle. ein Korinth, das durch Chromieren röter wird.Example 1 2. i9 # 9 parts q. # 6-Dinitro-2-amino-i-oxybenzene are diazotized in the usual way and with a soda-alkaline solution of 22 # 5 parts of 8-oxyquinoline-5-sulfonic acid combined. The deposited dye dyes on wool. a Corinth that is reddened by chrome plating.

Der Farbstoff aus diazotierter q.-Nitro-2-amino-i-oxybenzol-6-sulfosäure und 8-Oxychinolin-5-sulfosäure färbt Wolle direkt schwärzlich violett, nachchromiert Bordeaux:The dye from diazotized q.-nitro-2-amino-i-oxybenzene-6-sulfonic acid and 8-oxyquinoline-5-sulfonic acid directly dyes wool blackish violet, after chrome-plating Bordeaux:
