Description
Verfahren zur Herstellung eines Anthrachinonküpenfarbstoffes. Es wurde gefunden, dass man zu einem wertvollen Anthrachinonküpenfarbstoff ge langt, wenn man 1,4-Diamino-2-(p-methyl- benzoyl)-anthrachinon mit einem den p-Chlor- benzoylrest abgebenden Mittel behandelt.
Der neue Farbstoff, das 1-Amino-4-(p- chlorbenzoylamino) -2- (p-methylbenzoyl) -an- thrachinon, löst sich in konz. Schwefelsäure mit olivgrüner Farbe und ergibt auf Baum wolle gedruckt rotstichig blaue Töne.
Als den p-Chlorbenzoylrest abgebende Mit tel kommen vorzugsweise Halogenide, insbe sondere das Chlorid der p-Chlorbenzoesäure, in Betracht. Die Umsetzung erfolgt zweek- mässig in einem organischen Lösungsmittel wie o-Dichlorbenzol und bei erhöhter Tem peratur,
gegebenenfalls unter Zusatz eines säurebindenden Mittels wie Pyridin. Nach dem vorliegenden Verfahren wird nur die in der 4-Stellung des Anthrachinonrestes befind liche Aminogruppe in der angegebenen Weise acyliert, während die in 1-Stellung befind liche Aminogruppe zufolge der Anwesenheit der Ketogruppe in 2-Stellung unverändert bleibt.
<I>Beispiel:</I> Man erhitzt eine Mischung von 3 Teilen 1,4-Diamino-2- (p-methylbenzoyl)-anthrachi- non, 2,2 Teilen p-Chlorbenzoylchlorid, 60 Vo- lumteilen Chlorbenzol und 3 Volumteilen Py- ridin unter Rühren eine halbe bis eine Stunde auf 110 bis l15 , lässt auf 50 abkühlen, fil triert den Farbstoff ab und trocknet ihn.
Das 1,4-Diamino-2-(p-methylbenzoyl).an- thrachinon kann wie folgt hergestellt werden: 17 Teile 1,4-Di-(p-toluolsulfamino)-2-(p-me- thylbenzoyl)-anthrachinon (hergestellt durch Verschmelzen von 1,4-Dichlor-2- [p-methyl- benzoyl]-anthrachinon mit, p-Toluolsulfamid;
nach dem Umkristallisieren aus wässerigem Pyridin liegt es als einheitlich gelbes Kristall pulver vor) werden in 120 Volumteilen 98 % iger Flusssäure gelöst. Man rührt so lange bei 0 bis 5 , bis die mit dem Kupfer draht entnommenen und in Essigester gelösten Proben keine Farbtonverschiebung nach Blau anzeigen, was nach sechs bis sieben Stunden der Fall ist.
Dann giesst man die Lösung auf Eis, stellt mit Ammoniak alkalisch, verrührt bis zum Verschwinden des Toluolsulfofluorids und filtriert das entstandene 1,4-Diamino-2- (p-methylbenzoyl) -anthrachinon ab.
Process for the preparation of an anthraquinone vat dye. It has been found that a valuable anthraquinone vat dye is obtained if 1,4-diamino-2- (p-methylbenzoyl) anthraquinone is treated with an agent which releases the p-chlorobenzoyl radical.
The new dye, 1-amino-4- (p-chlorobenzoylamino) -2- (p-methylbenzoyl) -anthrachinon, dissolves in conc. Sulfuric acid with an olive green color and, when printed on cotton, produces reddish blue tones.
Halides, in particular the chloride of p-chlorobenzoic acid, are preferably used as the means for releasing the p-chlorobenzoyl radical. The reaction takes place in an organic solvent such as o-dichlorobenzene and at an elevated temperature,
optionally with the addition of an acid-binding agent such as pyridine. According to the present process, only the amino group in the 4-position of the anthraquinone residue is acylated in the manner indicated, while the amino group in the 1-position remains unchanged due to the presence of the keto group in the 2-position.
<I> Example: </I> A mixture of 3 parts 1,4-diamino-2- (p-methylbenzoyl) anthraquinone, 2.2 parts p-chlorobenzoyl chloride, 60 parts by volume of chlorobenzene and 3 parts by volume is heated Pyridine with stirring for half an hour to an hour to 110 to 115, allowed to cool to 50, filters off the dye and dries it.
The 1,4-diamino-2- (p-methylbenzoyl) .anthraquinone can be prepared as follows: 17 parts 1,4-di- (p-toluenesulfamino) -2- (p-methylbenzoyl) anthraquinone ( produced by fusing 1,4-dichloro-2- [p-methylbenzoyl] anthraquinone with p-toluenesulfamide;
After recrystallization from aqueous pyridine, it is a uniformly yellow crystal powder) are dissolved in 120 parts by volume of 98% hydrofluoric acid. The mixture is stirred at 0 to 5 until the samples taken with the copper wire and dissolved in ethyl acetate show no color shift to blue, which is the case after six to seven hours.
The solution is then poured onto ice, made alkaline with ammonia, stirred until the toluenesulfofluoride has disappeared and the 1,4-diamino-2- (p-methylbenzoyl) anthraquinone formed is filtered off.
