Description

Verfahren zur Herstellung von grünen Trisazofarbstoffen Es wurde gefunden, daß man neue, wertvolle grüne Tnisazofarbstoffe erhält, wenn man 1 Mol tetrazotiertes 4, 4'-Diaminodiphenylsulfid zunächst in saurem Medium mit 1 Mol 1-Amino-8-oxynaphbhalin-3, 6-disu:lfensäure kuppelt und auf die erhaltene Diazcxazoverbindung in schwach alkalischem Medium 1 Mol diazotiertes 4-Nitroanilin und nach dessen Verbrauch 1 Mol eines Phenols oder einer 1, 3-Dioxyverbindung der Benzolreihe einwirken läßt.Process for the production of green trisazo dyes It has been found that you get new, valuable green Tnisazo dyes if you 1 mol tetrazotized 4, 4'-Diaminodiphenylsulfid first in acidic medium with 1 mol 1-Amino-8-oxynaphbhalin-3, 6-disu: lfenic acid coupled and on the diazocxazo compound obtained in weakly alkaline Medium 1 mole of diazotized 4-nitroaniline and, after its consumption, 1 mole of a phenol or a 1,3-dioxy compound of the benzene series can act.

Geeignete Phsnole bzw. 1, 3-Dioxyve.rbindungen der Benzolreille sind z. B. das Phenol selbst, die Kresolt und Xylenole, das Resorcin und das 4-Methyl-1, 3-dioxybenzol.Suitable Phsnole or 1,3-Dioxyve.rbindungen of the Benzolreille are z. B. the phenol itself, the cresol and xylenols, the resorcinol and the 4-methyl-1, 3-dioxybenzene.

Die so erhaltenen grünen Trisazofarbstoffe der allgemeinen Formel in. der A den Rest des verwendeten Phenols bzw. 1, 3-Dioxybenzols bedeutet, eignen sich insbesondere zum Färbens von Leder, auf dem sie Färbungen von klaren Tönen und guten Echtheitseigenschaften ergeben. Dite Färbungen zeigen keine Neigung zum Broncieren. Gegenüber vergleichbaren Farbstoffen der deutschen Patentschriften 153557 und 917991 zeichnen, sich die neuen Farbstoffe durch besseres Durchfärbevermägen aus und ergeben daher Färbungen von besserer Schleifechtheit sowie von reineren Farbtönen.The green trisazo dyes of the general formula obtained in this way in. The A denotes the remainder of the phenol or 1,3-dioxybenzene used, are particularly suitable for dyeing leather, on which they give dyeings of clear shades and good fastness properties. Dite stains do not show any tendency to bronzing. Compared to comparable dyes of German patents 153557 and 917991 , the new dyes are distinguished by better through-dyeing power and therefore result in dyeings of better sanding fastness and of purer shades.

Die im Beispiel genannten Teile sind Gewichtsteile. Beispiel 22,2 Teile . 4, 4'-Diaminodiphein,vlsu;lfi(1 werden in 100 Teilen Wasser und 52 Teilen 10n-Salzsäure gelöst und in üblicher Weise mit einer Lösung von 14,3 Teilens Natriumnitrit tetrazotiert: Ein etwaiger Nitritübersch.uß wird nach 30 Minuten Rühren durch Zugabe kleiner Mengen Ami,nosulfonsäure entfernt.The parts mentioned in the example are parts by weight. Example 22.2 Parts. 4,4'-Diaminodiphein, vlsu; lfi (1 are in 100 parts of water and 52 parts Dissolved 10N hydrochloric acid and in the usual way with a solution of 14.3 parts of sodium nitrite tetrazotized: Any excess nitrite is removed by adding after 30 minutes of stirring small amounts of aminosulfonic acid removed.

Dann läßt man in die Tetrazolösung unter Rühren eine l.äsu!ng von 33,6 Teilen 1-Amino-8-o,xynaphth,alin-3, 6-di:sulfonisäure in 300 Teilen Wasser, die mit Natriumcarbonat auf den pH-Wert 6.5 eingestellt wurde, einlaufen, setzt weitere 5,3 Teile wasserfreies Natriumcarbonat hinzu und rührt 12 Stunden weiter. Nun wird auf 5° abgekühlt und eine in üblicher Weise aus 13,8 Teilen 4-Nitroanilin hergestellte Diazolöslung und dann so viel Natriumcarbonat (etwa 31 Teile) eingerührt, daß das Gemisch eben auf Brillantgelbindikator anspricht. Wenn nach etwa 30 Minuten alles 1)-Nitrobenzoldiazoniwmchlorid verbraucht ist, fügt man eine Lösung von 11 Teilen 1, 3-Dioxybenzol und 16 Teilen wasserfreiem Natriumcarbonat in 100 Teilen Wasser hinzu und rührt 12 Stunden bei gewöhnlicher Temperatur, dann 2 weiteire Stunden bei 40°, worauf man den Farbstoff mit 200 Teilen Natriumchlorid ausisalzt, absaugt, mit halbgesättigter Natriunlchloridläsung wäscht und bei 70° trocknet.A l.supply of 33.6 parts of 1-amino-8-o, xynaphth, alin-3, 6-di: sulfonic acid in 300 parts of water, which was adjusted to pH 6.5 with sodium carbonate, runs in, sets a further 5.3 parts of anhydrous sodium carbonate are added and the mixture is stirred for a further 12 hours. It is then cooled to 5 ° and one in the usual way from 13.8 parts of 4-nitroaniline prepared diazo solution and then stirred in enough sodium carbonate (about 31 parts), that the mixture responds to brilliant yellow indicator. If after about 30 minutes all 1) -nitrobenzene diazonium chloride is consumed, a solution of 11 is added Parts of 1, 3-dioxybenzene and 16 parts of anhydrous sodium carbonate in 100 parts Add water and stir for 12 hours at ordinary temperature, then for 2 more hours at 40 °, whereupon the dye is salted out with 200 parts of sodium chloride, filtered off with suction, Washed with half-saturated sodium chloride solution and dried at 70 °.

Der so erhaltene Farbstoff ist ein dunkles Pulver, das sich in Wasser mit grüner Farbe löst und Leder iri satten Grüntönen färbt.The resulting dye is a dark powder that dissolves in water dissolves with green paint and dyes leather in rich green tones.

Verwendet man zur letzten Kupplung an Stelle von 11 'feilen 1, 3-Dioxybenzol 9,4 Teile Phenol, so erhält Inan einten etwas blaustichigeren Farbistoff. Verwendet inan 10,8 Teile 4-Methylphenol, so wird der Farbton noch weiter nach Blau verschoben, ohne daß die sonstigen Eigenschaften nachteilig verändert werden.For the last coupling, 1,3-dioxybenzene is used instead of 11 'files 9.4 parts of phenol gives Inan a somewhat bluish dye. Used inan 10.8 parts of 4-methylphenol, the hue is shifted even further to blue, without the other properties being adversely affected.
