Patentiert im Deutschen Reiche vom 6. Oktober 1908 ab.Patented in the German Empire on October 6, 1908.

Es wurde gefunden, daß sich die Alkyl- und Aryläther des 5-Nitro-2-aminophenols, wie z.B. das 5-Nitro-o-aniinoanisol (NO2:NH2: OC Ha = 5 :2 : τ), und ihre Derivate und Substitutionsprodukte in saurer Lösung mit arylierten Derivaten der 2-Amino-8-naphtol-6-sulfosäure γ zu Monoazofarbstoffen vereinigen lassen, die Wolle aus saurem Bade in blumigen schwarzen Tönen anfärben und überraschenderweise die Eigenschaft, vorzüglich zu egalisieren, mit guter Walk- und Lichtechtheit in sich vereinigen.It has been found that the alkyl and aryl ethers of 5-nitro-2-aminophenol, such as 5-nitro-o-aniinoanisole (NO 2 : NH 2 : OC H a = 5: 2: τ), and their Let derivatives and substitution products combine in acidic solution with arylated derivatives of 2-amino-8-naphthol-6-sulfonic acid γ to form monoazo dyes, dye the wool from acidic baths in flowery black tones and, surprisingly, the property of excellent leveling, with good fulling and unite lightfastness.

Beispiel.Example.

168 Teile 5-Nitro-2-aminoanisol werden mit 1000 Teilen 20 prozentiger Salzsäure und 700 Teilen Wasser kochend gelöst, durch Zusatz von Eis auf 15 ° abgekühlt und mit 69 Teilen Nitrit versetzt. Die Diazoverbindung wird nach dem Filtrieren mit Natriumacetatlösung abgestumpft, bis nur noch schwach kongosaure Reaktion vorhanden ist. Bei 5° wird die Diazoverbindung darauf zu einer Lösung von 315 Teilen 2-Phenylamino-8-naphtol-6-sulfosäure und 136 Teilen kristallisiertem Natriumacetat in Wasser zugefügt. Nach kurzer Zeit ist die Kuppelung beendet. Der Farbstoff wird in der üblichen Weise isoliert.168 parts of 5-nitro-2-aminoanisole with 1000 parts of 20 percent hydrochloric acid and 700 Parts of water dissolved at the boil, cooled to 15 ° by adding ice and with 69 parts Nitrite added. The diazo compound is after filtering with sodium acetate solution blunted until only a weak Congo acidic reaction is present. At 5 ° becomes then add the diazo compound to a solution of 315 parts of 2-phenylamino-8-naphthol-6-sulfonic acid and 136 parts of crystallized sodium acetate in water were added. After short Time the coupling is over. The dye is isolated in the usual way.

Der Farbstoff erzeugt auf Wolle in saurem Bade ein volles Schwarz.The dye produces a full black on wool in an acidic bath.

Ganz ähnliche Farbstoffe werden erhalten, wenn man die 2 - Phenylamino - 8 - naphtol - 6-sulfosäure durch andere Arylderivate der 2 · 8 · 6- Aminonaphtolsulfosäure ersetzt, wie z. B. p-Tolyl-, Xylyl-, p-Anisidyl-, m-Carboxyphenyl-2 · S-aminonaphtol-ö-sulfosäure. An Stelle von diazotiertem 5-Nitro-2-aminoanisol können auch die Diazoverbindungen von anderen Äthern des 5-Nitro-2-aminophenols oder deren Derivate und Substitutionsprodukte benutzt werden, wie z. B. 5-Nitro-4-chlor-2-aminoanisol, 5-Nitro-4-methyl-2-aminoanisol, 5-Nitro-2-aminophenetol, der Phenyläther des 5-Nitroaminophenols usf.Very similar dyes are obtained if you add 2 - phenylamino - 8 - naphthol - 6-sulfonic acid replaced by other aryl derivatives of 2 · 8 · 6-aminonaphthol sulfonic acid, such as z. B. p-tolyl-, xylyl-, p-anisidyl-, m-carboxyphenyl-2 · S-aminonaphthol-6-sulfonic acid. At Instead of diazotized 5-nitro-2-aminoanisole, the diazo compounds of others can also be used Ethers of 5-nitro-2-aminophenol or their derivatives and substitution products are used become, such as B. 5-nitro-4-chloro-2-aminoanisole, 5-nitro-4-methyl-2-aminoanisole, 5-nitro-2-aminophenetol, the phenyl ether of 5-nitroaminophenol, etc.
