Description

Verfahren zur Darstellung von blonoazofarbstoffen für Wolle. Es wurde gefunden, daß wertvolle Wollfarbstoffe dadurch erhalten werden, daß man Diazoverbindungen der Benzolreihe, die eine Alk-vlacet laminogruppe enthalten, mit Aryly b aininonaphtholstilfosätiren und ihrenDerivaten kuppelt.Process for the preparation of blonoazo dyes for wool. It has been found that valuable wool dyes are obtained by reacting diazo compounds of the benzene series, which contain a vlacet Alk-laminogruppe, aininonaphtholstilfosätiren with Aryly b and coupling their derivatives.

Die so erhältlichen Farbstoffe sind dadurch besonders wertvoll, daß sie gut egalisieren, sehr leicht löslich sind und trotz ihrer leichten Löslichkeit gute Walkechtheit zeigen.The dyes obtainable in this way are particularly valuable in that they level well, are very easily soluble and despite their easy solubility show good flexing fastness.

Beispiel i.Example i.

17,8 Gewichtsteile p-Ai-ninoät-hylacetan#ilid iverden, wie üblich, diazotiert und die Diazoverbindung zu einer sodaalkalischen Lösung Von 35 Gewichtsteilen o-Methoxyphenyl-2-amino-8-naphthol-6-stilfosätire (iooprozentig) gegeben.17.8 parts by weight of p-aminoeth-hylacetanilide are diazotized, as usual, and the diazo compound is added to a soda-alkaline solution of 35 parts by weight of o-methoxyphenyl-2-amino-8-naphthol-6-stilfosätire (10%).

Der ausgesalzene Farbstoff färbt Wolle in braunen Tönen an.The salted-out dye stains wool in brown tones.

Beispiel 19,2 Gewichtsteile 2-Äthylacetylamiilo-4-toluidiii werden, wie üblich, diazotiert und die Diazoverbindung zu einer sodaalkalischen Lösung von 32 Gewichtsteilen Phenyl-2-amino-8-naphtliol-6-stilfosätire (iooprozentig) gegeben.Example 1 9.2 parts by weight of 2-ethylacetylamiilo-4-toluidiii are diazotized as usual and the diazo compound is added to an alkaline soda solution of 32 parts by weight of phenyl-2-amino-8-naphthol-6-stilfosätire (10%).

Der ausgesalzene Farbstoff färbt Wolle braun an. Beispiel 3. The salted-out dye stains wool brown. Example 3.

19,2 Gewichtsteile 5-Äthylacetylainino-2-toluidin werden, wie üblich, diazotiert und die Diazoverbindung zu einer sodaallzalischen Lösung von 4o Gewichtsteilen p-Ätliylacetyl--irninophenyl-2-amiiio-S-naphtliol-6-stilfosätire (iooprozentig) gegeben.19.2 parts by weight of 5-Äthylacetylainino-2-toluidine are, as usual, diazotized and the diazo compound to a sodaallzalischen solution of 40 parts by weight p-Ätliylacetyl - iminophenyl-2-amiiio-S-naphthiol-6-stilfosätire (100 percent) given.

Der ausgesalzene Farbstoff färbt Wolle in Bordeauxtönen an.The salted-out dye stains wool in shades of Bordeaux.

Beispiel 4, 19,2 Gewichtsteile 4-Äthylacetylamilioo-toluidin werden, wie üblich, diazotiert und die Diazoverbindung zu einer sodaalkalischen Lösung von 35 Gewichtsteilen p-Methoxyphenyl-2-amino-8-naphthol-6-stilfosäure (iooprozentig) gegeben.Example 4, 19.2 parts by weight of 4-ethylacetylamilio-toluidine are diazotized as usual and the diazo compound is added to an alkaline soda solution of 35 parts by weight of p-methoxyphenyl-2-amino-8-naphthol-6-stilfonic acid (10%).

Der ausgesalzene Farbstoff färbt Wolle ge g lbstichigbraun an.The salted-out dye stains wool in a yellowish brown.
