Description
Verfahren zur Herstellung eines Trisazofarbstoffes. Es, wurde gefunden, dass man einen neuen wertvollen Trisazofarbstoff erhält, wenn
EMI0001.0003
mit N-4'-Oxy-3'-carboxyphenyl-1'-sulfonyl N-methyl-2-amino-5-oxynaphthalin-7-sulfon- säure entsprechend der Formel
EMI0001.0006
kuppelt.
Der neue Trisazofarbstoff färbt in blauen Tönen, zieht substantiv auf Baumwolle, man die Diazoverbindung des Aminodisazo- farbstoffes der Formel Viskosekunstseide oder Leinen und lässt sich im Gemisch mit Wollfarbstoffen zum Färben von Wolle-Baumwolle- oder Wolle-Viskose- kunstseidemischungen verwenden. Die Echt heit der Färbungen kann durch Nachbehand lung mit Kupfer- oder Chromsalzlösungen noch verbessert werden.
<I>Beispiel:</I> Man löst 352 Teile N-3'-Aminobenzoyl-l- amino - 3 - carboxy- 4-oxybenzol - 5-sulf onsäure in wässriger Natronlauge, gibt 69 Teile Na- triumnitrit hinzu und lässt in verdünnte Salz säure bei 20 C einlaufen. Darauf setzt man eine neutrale Lösung von 223 Teilen 1- Aminonaphthalin-7-sulfonsäure hinzu und bringt die Kupplung durch Zugabe von Natriumacetat zu Ende.
Der sich abschei dende Aminoazofarbstoff wird durch Zusatz von Natronlauge gelöst, mit 69 Teilen Na triumnitrit versetzt, durch Zugabe von Salz säure diazotiert und mit einer neutralen Lö sung von 223 Teilen 1-Aminonaphtha,lin-7- sulfonsäure unter Zusatz von Natriumacet;at zum Disazofarbstoff vereinigt.
Der Disazo- farbstoff wird aus der alkalisch gemachten Lösung ausgesalzen, abgesaugt, wieder unter Zusatz von Alkalihy droxyd in Lösung ge bracht,
unter Eiskühlung mit 69 Teilen Na- triumnitrit -"-ersetzt und durch Zuhabe von Salzsäure bis zur schwach sauren Reaktion diazotiert. Die Diazoverbindung lässt man in eine alkalische Lösung von 453 Teilen N-4' Oxy-3'-carboxy pheilyl-1'-sulfonyl-N-methyl- 2-amino-5-oxynaphthalin-7-sulfonsäure ein laufen.
Der so erhältliche Trisazofarbstoff färbt Baumwolle und Viskosekunstseide in blauen Tönen, die durch Nachbehandeln mit Chromi- salzlösungen eine vorzügliche Waschechtheit erlangen.
Process for the preparation of a trisazo dye. It has been found that a new valuable trisazo dye is obtained when
EMI0001.0003
with N-4'-oxy-3'-carboxyphenyl-1'-sulfonyl N-methyl-2-amino-5-oxynaphthalene-7-sulfonic acid according to the formula
EMI0001.0006
clutch.
The new trisazo dye dyes in blue tones, draws substantive to cotton, the diazo compound of the aminodisazo dye of the formula viscose rayon or linen and can be used in a mixture with wool dyes for dyeing wool-cotton or wool-viscose rayon blends. The authenticity of the dyeings can be improved by post-treatment with copper or chromium salt solutions.
<I> Example: </I> 352 parts of N-3'-aminobenzoyl-1-amino-3-carboxy-4-oxybenzene-5-sulfonic acid are dissolved in aqueous sodium hydroxide solution, 69 parts of sodium nitrite are added and allowed to take place run in dilute hydrochloric acid at 20 C. A neutral solution of 223 parts of 1-aminonaphthalene-7-sulfonic acid is then added and the coupling is brought to an end by adding sodium acetate.
The aminoazo dye which separates out is dissolved by adding sodium hydroxide solution, 69 parts of sodium nitrite are added, diazotized by adding hydrochloric acid and a neutral solution of 223 parts of 1-aminonaphtha, lin-7-sulfonic acid with the addition of sodium acetate; Disazo dye combined.
The disazo dye is salted out of the alkaline solution, filtered off with suction, brought back into solution with the addition of alkali hydroxide
with 69 parts of sodium nitrite - "- replaced with ice-cooling and diazotized by adding hydrochloric acid to a weakly acidic reaction. The diazo compound is left in an alkaline solution of 453 parts of N-4 'oxy-3'-carboxy pheilyl-1'- sulfonyl-N-methyl-2-amino-5-oxynaphthalene-7-sulfonic acid run.
The trisazo dye that can be obtained in this way dyes cotton and viscose rayon in blue tones, which, after treatment with chromium salt solutions, achieve excellent washfastness.
