Description
Verfahren zur Herstellung eines Polyazofarbstoffes. Es wurde gefunden, dass man einen neuen Polyazofarbstoff erhalten kann, wenn man auf 1 Hol Cyanurchlorid 1 Hol des Monoazofarbstoffes aus diazotierter 2-(3'- Aminobenzoylamino) - naphthalin - 4,8 -,disul- fonsäure und 1-Methyl-3-aminobenzol und 2 Hol 4-Amino - 4'- ogyazobenzol-3'-carbon- säure einwirken lässt.
Der neue Polyazofarb- stoff färbt Baumwolle in schwach alkali schem Bade bei Gegenwart von Kupfersulfat und weinsaurem Natrium in waschechten grünstichig gelben Tönen an.
Beispiel: 54 Gewichtsteile des Monoazofarbstoffes aus diazotierter 2-(3'-Aminobenzoylamino)- na.phthalin-4,8--disulfonsäure und 1-Methyl- 3-aminobenzol werden in neutraler wässriger Lösung zu einer kalten wässrigen Anschläm- mung von 18,4 Gewichtsteilen Cyanurchlorid gegeben. Die dabei entstehende Salzsäure wird durch die entsprechende Menge Na- triumca.rbonat neutralisiert.
Hernach wer den 27,8 Gewichtsteile 4-amino-4'-ogyazo- benzol-3'-carbonsaures Natrium, das in Was ser gelöst wurde, zugefügt und die Tempe ratur auf 40 erhöht. Nach 2 Stunden gibt man weitere 24 Teile 4-amino-4'-ogyazoben- zol-3'-carbonsaures Natrium zu und hält die Temperatur während der gleichen Zeit auf <B>80'.</B> Das tertiäre Kondensationsprodukt ist nach dieser Zeit gebildet. Es wird mittelst Natriumchlorid abgeschieden und getrocknet.
Zum gleichen Polyazofarbstoff gelangt man, wenn man auf das Cyanurchlorid die drei Hol Farbstoff in einer andern Reihen- fo ke einwirken lässt.
Process for the preparation of a polyazo dye. It has been found that a new polyazo dye can be obtained if one pole of the monoazo dye from diazotized 2- (3'-aminobenzoylamino) naphthalene-4,8 -, disulfonic acid and 1-methyl-3- aminobenzene and 2 Hol 4-amino-4'-ogyazobenzene-3'-carboxylic acid can act.
The new polyazo dye dyes cotton in a weakly alkaline bath in the presence of copper sulfate and tartrate of sodium in washfast greenish yellow tones.
Example: 54 parts by weight of the monoazo dye from diazotized 2- (3'-aminobenzoylamino) - na.phthalin-4,8 - disulfonic acid and 1-methyl-3-aminobenzene are in neutral aqueous solution to form a cold aqueous slurry of 18, Given 4 parts by weight of cyanuric chloride. The resulting hydrochloric acid is neutralized by the appropriate amount of sodium carbonate.
Afterwards who the 27.8 parts by weight of 4-amino-4'-ogyazobenzene-3'-carboxylic acid sodium, which was dissolved in water, added and the temperature increased to 40. After 2 hours, a further 24 parts of 4-amino-4'-ogyazoben-zol-3'-carboxylic acid sodium are added and the temperature is maintained at 80 'for the same time. The tertiary condensation product is after this Time formed. It is precipitated by means of sodium chloride and dried.
The same polyazo dye is obtained if the three hol dyes are allowed to act on the cyanuric chloride in a different series.
