Description
Verfahren zur Herstellung eines stielistoffhaltigen Küpenfarbstoffes. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung eines stickstoff haltigen Küpenfarbstoffes, dadurch gekenn zeichnet, dass man Bz.1 -Benzarithroriyl-l- amirio 5-hexahydroanilidoanthrachiiioci mit ei nem alkalischen Kondensationsmittel behan delt.
Der neue Farbstoff löst sich in konzen trierter Schwefelsäure mit grüner Farbe und färbt Baumwolle aus violettblauer Küpe in echten blaugrauen Tönen. Durch Umlösen des Farbstoffes in konzentrierter Schwefelsäure wird das i'galisierungsvermögen noch ver bessert.
<I>Beispiel</I> 50 Teile Bz. 1-Benzarithronyl-l-amino-5- hexahydroanilidoarithrachinon werden allmäh lich in eine auf 150-160 gehaltene Schmelze von 300 Teilen Ätzkali und 50 Teilen Alko hol eingetragen. Die Reaktionstemperatur lässt man hierauf auf 180-200 steigen und verdünnt nach etova 1 Stunde die Schmelze mit Wasser. Der Farbstoff wird entweder durch Ausblasen mit Luft oder durch An säuern unter Zugabe einer geringen Menge eines Oxydationsmittels, wie Wasserstoff superoxyd, abgeschieden und gewaschen.
Das als Ausgangskörper benuzte Bz.1- Benzantronyl - l - amino- 5-hexahydroanilidoan- thrachinon wird erhalten durch Kondensation von Bz.1-Brombenzanthron mit 1-Ainino-5- hexahydroanilidoanthrachinon. Das Konden sationsprodukt löst sich in konzentrierter Schwefelsäure mit gelbbrauner Farbe, die auf Zusatz vor) Paraformaldehyd nach Blau umschlägt;
mit Hydrosulfit und Lauge ist das Produkt nicht verküpbar.
Das oben verwendete 1-Aiiiino-5-hexa- hy droanilidoanthrachinon lässt sich seinerseits durch Umsetzung von 1-Amirio-5-cbloran- thrachinon mit Hexahydroanilin herstellen. Es ist eine kristallisierte rote Substanz vorn Schmelzpunkt 174' und löst sich in konzen- trierter Schwefelsäure fast farblos auf. Auf Zusatz von Paraformaldehyd wird die Lö sungsfarbe violettstichig blau.
Process for the production of a vat dye containing stalk. The present patent relates to a process for the production of a nitrogen-containing vat dye, characterized in that Bz.1 -Benzarithroriyl-l-amirio 5-hexahydroanilidoanthrachiiioci treated with an alkaline condensing agent.
The new dye dissolves in concentrated sulfuric acid with a green color and dyes cotton from a violet-blue vat in real blue-gray tones. By redissolving the dye in concentrated sulfuric acid, the capacity for imbalance is further improved.
<I> Example </I> 50 parts Bz. 1-Benzarithronyl-l-amino-5-hexahydroanilidoarithraquinone are gradually introduced into a melt of 300 parts of caustic potash and 50 parts of alcohol held at 150-160. The reaction temperature is then allowed to rise to 180-200 and after about 1 hour the melt is diluted with water. The dye is deposited and washed either by blowing with air or by acidifying with the addition of a small amount of an oxidizing agent such as hydrogen superoxide.
The Bz.1-benzantronyl-l-amino-5-hexahydroanilidoanthraquinone used as the starting material is obtained by condensation of Bz.1-bromobenzanthrone with 1-amino-5-hexahydroanilidoanthraquinone. The condensation product dissolves in concentrated sulfuric acid with a yellow-brown color, which turns blue when added before) paraformaldehyde;
the product cannot be vetted with hydrosulphite and lye.
The 1-alino-5-hexahydroanilidoanthraquinone used above can in turn be prepared by reacting 1-amirio-5-cbloranthrachinone with hexahydroaniline. It is a crystallized red substance with a melting point of 174 'and dissolves almost colorlessly in concentrated sulfuric acid. When paraformaldehyde is added, the solution color turns purple-tinged blue.
