<B>Zusatzpatent</B> zum Hauptpatent Nr. 287872. Verfahren zur Herstellung eines Leukoschwefelsäureestersalzes eines Anthrachinonazofarbsto$es. Gegenstand vorliegender Erfindung ist ein Verfahren zur Herstellung eines neuen Leukoschwefelsäureestersalzes des Anthrachi- nonazofarbstoffes der Formel
EMI0001.0008
welches dadurch gekennzeichnet ist, dass man diazotiertes 1-Aminoanthrachinon mit 5-Aceto- acetylamino - 6 - methoxy- 2-phenyl-1,
3-benzo - triazol der Formel
EMI0001.0016
kuppelt und den entstandenen Azofarbstoff zur Leukoverbindung reduziert, diese durch Behandlung mit S03 oder S03. abgebenden Mitteln verestert und den Ester in das Na triumsalz überführt.
Die Überführung des Küpenfarbstoffes in den Leukoschwefelsäureester geschieht in der Weise, dass man z. B. den Farbstoff durch ein Reduktionsmittel, das wohl die Chinon- gruppe, nicht aber die Azogruppe reduziert, in die Leukoverbindung verwandelt und diese mit S03 oder einer S03 abgebenden Substanz, wie z. B. Chlorsulfonsäure, in Gegenwart einer tertiären Base, wie z. B. Pyridin, und in Gegen wart eines Metalles, wie z.
B. Cu oder Fe, ver- estert.
Der neue Leukoschwefelsäureester zeichnet sich durch eine gute Affinität zur vegetabili schen Faser und durch sehr gute Echtheiten aus.
<I>Beispiel:</I> 25 Teile des Azofarbstoffes aus diazotier- tem 1-Aminoanthrachinon und 5-Acetoacetyl- amino-6-methoxy-2-phenyl-1,3-benzotriazol und 25 Teile Eisenpulver werden während 5 Stun den mit einem Gemisch aus 37 Teilen Chlor- sulfonsäure und 180 Teilen Pyridin vom Siedepunkt 125 bis 128 C bei 40 bis 50 C verrührt.
Man giesst die Reaktionsmasse in eine Lösung von 60 Teilen Natriumearbonat in 1000 Teile Wasser, destilliert das Pyridin im Vakuum ab, befreit vom Eisenschlamm durch Filtration und salzt aus der erhaltenen Lösung den Ester mit Kochsalz aus.
Das neue Leukoschwefelsäureestersalz ist in Wasser unter Bildung einer gelborangen Lösung löslich und liefert durch geeignete Oxydation einen gelben Küpenfarbstoff. Nach dem für diese Farbstoffklasse üblichen Ent wicklungsverfahren wird auf der Faser ein rotstichiges Gelb mit sehr guten Echtheits eigenschaften erhalten.
<B> Additional patent </B> to main patent No. 287872. Process for the production of a leuco-sulfuric acid ester salt of an anthraquinone-azo dye. The present invention relates to a process for the preparation of a new leuco-sulfuric acid ester salt of the anthraquinoneazo dye of the formula
EMI0001.0008
which is characterized in that diazotized 1-aminoanthraquinone with 5-aceto-acetylamino-6-methoxy-2-phenyl-1,
3-benzo - triazole of the formula
EMI0001.0016
couples and reduces the resulting azo dye to the leuco compound, this by treatment with S03 or S03. esterified donor agents and converted the ester into the sodium salt.
The conversion of the vat dye into the leuco sulfuric acid ester is done in such a way that one z. B. the dye by a reducing agent, which probably reduces the quinone group, but not the azo group, converted into the leuco compound and this with SO3 or a substance releasing SO3, such as. B. chlorosulfonic acid, in the presence of a tertiary base, such as. B. pyridine, and in the presence of a metal such.
B. Cu or Fe, esterified.
The new leuco sulfuric acid ester is characterized by a good affinity for vegetable fibers and very good fastness properties.
<I> Example: </I> 25 parts of the azo dye from diazotized 1-aminoanthraquinone and 5-acetoacetylamino-6-methoxy-2-phenyl-1,3-benzotriazole and 25 parts of iron powder are with the for 5 hours a mixture of 37 parts of chlorosulfonic acid and 180 parts of pyridine with a boiling point of 125 to 128 C at 40 to 50 C stirred.
The reaction mass is poured into a solution of 60 parts of sodium carbonate in 1000 parts of water, the pyridine is distilled off in vacuo, the iron sludge is removed by filtration and the ester is salted out from the resulting solution with common salt.
The new leucosulfuric acid ester salt is soluble in water to form a yellow-orange solution and, through suitable oxidation, produces a yellow vat dye. After the development process customary for this class of dyes, a reddish yellow with very good fastness properties is obtained on the fiber.
