Description
Verfahren zur Herstellung von sauren Monoazofarbstoffen für Wolle. Es wurde gefunden, daß wertvolle Woll-;arbstoffe# dadurch erhalten werden, daß man Diazoverbindungen der Benzolreilie, die eine -M1,zvlacetvlaminogruppe enthalten, mit im Ar#Ikern haloggenierten und stilfierten Arylniethylpyrazolonen vereinigt.Process for the preparation of acidic monoazo dyes for wool. It has been found that valuable wool; dyes # are obtained by Diazo compounds of the benzene series, which contain an -M1, zvlacetvlamino group, combined with arylniethylpyrazolones halogenated and stylized in the aromatic nucleus.
Die neuen Farbstoffe sind dadurch besonders wertvoll, daß sie bei hervorragend klaren, grünstichiggelben Tönen vorzüglich egalisieren, sehr gut lichtecht und sehr leicht löslich sind und trotz ihrer leichten Löslichkeit gute Walkechtheit aufweisen.The new dyes are particularly valuable because they are at Excellent equalization of clear, greenish yellow tones, very good lightfast and are very easily soluble and, despite their ready solubility, have good flexing fastness exhibit.
Beispiel i.Example i.
19,2 Gewichtsteile 5-Ätlivlacetvlarnino-2-toluidin werden, wie üblich, diaz(#tiert und clie Diazoverbindung zu einer sodaalkalischen Lö-SUng Von 29 Gewichtsteilen 2-ChlOr-5-stIlf0-1)henvlmethylpyrazolon (iooprozentig) ge-Cleben.19.2 parts by weight of 5-Ätlivlacetvlarnino-2-toluidine are, as usual, diaz (#tiert and the diazo compound to a soda-alkaline solution of 29 parts by weight 2-chloro-5-stIlf0-1) henvlmethylpyrazolon (10%) ge-Cleben.
Der ausgesalzene Farbstoff färbt Wolle in klaren, gelben Tönen an.The salted-out dye stains wool in clear, yellow tones.
Beispiel 2.Example 2.
19,2 Gewichtsteile 4-Ätllylacetylamifio-2-to-Itlidin werden, wie üblich, diazotiert und die Diazoverbindung zu einer so#daalkalischen Lösung von 29 Gewichtsteilen 2-.Chlor-4-sulfoplienvimethylpyrazolon (iooprozentig) gegeben.19.2 parts by weight of 4-Ätllylacetylamifio-2-to-Itlidin are, as usual, diazotized and the diazo compound to form an alkaline solution of 29 parts by weight 2-.Chlor-4-sulfoplienvimethylpyrazolon (10%) given.
Der ausgesalzene Farbstoff färbt Wolle in klaren, grünstichiggelben Tönen an.The salted-out dye dyes wool in clear, greenish yellow Tones on.
1 Beispiel 3. 1 example 3.
19,2 Gewichtsteile 2-Äthylacetylamin0-4-tO-luidin werden, wie üblich, diazotiert und die Diazoverbindung zu einer sodaalkalischen Lösung von 33 Gewichtsteilen 2-5-Dichlor-4-sulfophenylmethylpyrazolon (iooprozentig) gegeben.19.2 parts by weight of 2-Äthylacetylamin0-4-tO-luidine are, as usual, diazotized and the diazo compound is added to an alkaline soda solution of 33 parts by weight of 2-5-dichloro-4-sulfophenylmethylpyrazolone (10%).
Der ausgesalzene Farbstoff färbt Wolle in klaren, grünstichiggelben Tönen an.The salted-out dye dyes wool in clear, greenish yellow Tones on.
