Description
Verfahren zur Herstellung eines ehromierbaren Monoazofarbstofes. Es wurde gefunden, dass man zu .einem wertvollen, chromierbaren Monoazofarbstoff gelangt, wenn man eine Aminosulfonsäure von folgender Formel
EMI0001.0011
diazotiert und mit 2-Amino-8-ogynaphthalin- 6-sulfonsäure in saurer Lösung kombiniert.
Der neue Farbstoff bildet ein dunkelrotes Pulver, löslich in Wasser mit rotvioletter, in konzentrierter Schwefelsäure mit roter Farbe und gibt in saurem Bad auf Wolle reine rot violette Färbungen, die durch Nachchromie- ren ohne wesentliche Änderung des Farb tones ausgezeichnet licht-, walk- und potting- echt werden, bei gleichzeitig vorzüglicher Ätzbarkeit. <I>Beispiel:
</I> 68,3 Teile der Verbindung
EMI0001.0030
erhalten durch Kondensation von 4-(3'-Amino- benzoyl) -amino- 2 - (1'-benzol - 4'-chlor-3'-eul- fon-l-aminobenzol mit 1-Ogy-2-carbosyben- zol-4-sulfochlorid in wässriger Lösung wer den abgekühlt und mit 7 Teilen Natrium- nitrit versetzt.
Dann wird in 60 Teile kon- zentrierter Salzsäure, mit Wasser und Eis verdünnt, langsam eingetragen, wobei der Diazokörper sich ausscheidet und hierauf fil triert wird. Mit Wasser angeteigt, wird er allmählich in eine Lösung von 26,2 Teilen Natriumsalz der 2-Amino-8-ogynaphtha.Iin- 6-sulfonsäure und 20 Teilen" Natriumacetat eingerührt. Nach 12 Stunden wird auf zirka <B>50'</B> C erwärmt und der Farbstoff aasgesalzt und getrocknet.
Er bildet, ein dunkelrotes Pulver, löslich in Wasser mit rotvioletter, in konzentrierter Schwefelsäure mit roter Farbe und gibt in saurem Bad auf Wolle reine rotviolette Fär bungen, die durch Nachchromieren ohne we sentliche Änderung des Farbtones ausgezeich net licht-, walk- und pottingecht werden, bei -leichzeitig vorzüglicher Ätzbarkeit.
Process for the preparation of an honorable monoazo dye. It has been found that a valuable, chromable monoazo dye is obtained if an aminosulfonic acid of the following formula is used
EMI0001.0011
diazotized and combined with 2-amino-8-ogynaphthalene-6-sulfonic acid in acidic solution.
The new dye forms a dark red powder, soluble in water with a red-violet color, in concentrated sulfuric acid with a red color and gives pure red-violet colorations to wool in an acid bath, which after chrome-plating without any significant change in color tone is excellent light, walk and Really potting, with excellent etchability at the same time. <I> example:
</I> 68.3 parts of the connection
EMI0001.0030
obtained by condensation of 4- (3'-amino-benzoyl) -amino-2 - (1'-benzene - 4'-chloro-3'-eulphone-1-aminobenzene with 1-Ogy-2-carbosybenzene -4-sulfochloride in aqueous solution who is cooled and mixed with 7 parts of sodium nitrite.
Then, in 60 parts of concentrated hydrochloric acid, diluted with water and ice, slowly introduced, the diazo body separating out and then being filtered. Made into a paste with water, it is gradually stirred into a solution of 26.2 parts of the sodium salt of 2-amino-8-ogynaphtha.Iin-6-sulfonic acid and 20 parts of sodium acetate. After 12 hours, the mixture is increased to about 50%. B> C warmed and the dye carrion salt and dried.
It forms a dark red powder, soluble in water with red-violet color, in concentrated sulfuric acid with red color and gives pure red-violet dyeings to wool in an acid bath, which are distinguished by re-chrome plating without any significant change in color shade, which is light, milled and potting-fast , with excellent etchability at the same time.
