Description
Verfahren zur Herstellung eines Monoazofarbstoffes. Gegenstand vorliegenden Patentes ist. ein Verfahren zur Herstellung eines Monoazo- farbstoffes. Das Verfahren ist dadurch ge kennzeichnet., dass man diazotiertes 6-Nitro-2- amino-4-tert.amyl-phenol mit. 1- (4'-Chlor phenyl)-5-pyrazolon-3-carbonsäuremethylanüd- 5"-sulfonsäureamid kuppelt.
Der erhaltene neue Farbstoff stellt. ein dunkles, violettes Pulver dar, das sich in heissem Wasser mit blauroter, in konz. Schwe felsäure mit orangebra,uner Farbe löst und Wolle nachchromiert blaustichig rot färbt.
Beispiel: 22,4 Teile 6-Nitro-2-amino-4-tert.amyl- phenol werden mit 4,1 Teilen Natriumhy droxyd in 200 Teilen Wasser gelöst, 6,9 Teile Na triumnitrit in 35 Teilen Wasser zugesetzt und die Mischung bei einer 3 nicht überschreiten den Temperatur auf 35 Volumteile konz. Salz säure in 100 Teilen Wasser getropft.
So er hält man eine gelblichgrüne Suspension des I)iazokörpers. Nach beendeter Diazotierung wird die Acidität der Diazosuspension mit Natriumbikarbonat bis kongoneutral abge stumpft, worauf eine Lösung von 33,5 Teilen 1-(4'-Chlor-phenyl)-5-py razolon-4-earbonsäure- niethylamid-5'-sulfonsäureamid und 8 Teilen Natriumhydroxyd in 100 Teilen Wasser von 0-3 zugegeben wird.
Das Reaktionsgemisch wird mit 10 Teilen Ammoniak 25o/oig schwach phenolphthaleinalkalisch gestellt. Dann lässt man die Temperatur langsam von 3 auf 20 steigen. Nach etwa 20 Stunden ist die Kupp- hing beendet. Der ausgeschiedene Farbstoff wird abfiltriert, mit Sole von 21/ /o gewaschen und getrocknet.
Der Farbstoff stellt ein dunkles, violettes Pulver dar, das sich in heissem Wasser mit blauroter, in konz. Schwefelsäure mit orange brauner Farbe döst. Für den Gebrauch wird das Produkt zweekmässigerweise mit etwas Natriumcarbonat und einem Dispergiermittel gut vermahlen. Der Farbstoff färbt Wolle aus saurem Bade mit gelbbraunem Farbton, der beim Nachchromieren in ein blaustichiges Rot übergeht.
Nach dem Einbadchromverfahren erhält man ohne oder mit nur geringem Säure zusatz unter völliger Erschöpfung des Färbe bades nuancen- und stärkegleiche Färbungen, die sehr gute Nass- und Lichtechtheiten auf weisen.
Das oben erwähnte Pyrazolon erhält man z. B. indem man 4-Chlor-anillin-5 sulfonsäure- amid nach bekannten Methoden in das ent sprechende Hydrazin überführt und dieses Hydrazin mit Natriumoxalessigsäureäthylester zum 1-(4'-Chlor-phenyl)-5-pyrazolon-3-carbon- säureäthylester - 5' - sulfonsäureamid konden siert.
Der erhaltene Pyrazolon-3-carbonsäure- ät.hylester wird dann mit etwa der fünffachen Menge 25o/oigem Methylamin angeschlämmt und entweder 2-4 Tage bei 20 stehengelassen oder 10-15 Stunden im Druckgefäss auf 80 bis 100 erwärmt. Der Py-razolon-3-carbon- säureester geht dabei in Lösung, der Alkohol rest des Esters wird abgespaltet und durch den Amidrest ersetzt.
Process for the preparation of a monoazo dye. Subject of the present patent is. a process for the preparation of a monoazo dye. The process is characterized in that one diazotized 6-nitro-2-amino-4-tert-amyl-phenol with. 1- (4'-chlorophenyl) -5-pyrazolone-3-carboxylic acid methylanüd-5 "-sulfonic acid amide couples.
The new dye obtained represents. a dark, violet powder, which in hot water with blue-red, in conc. Sulfur acid dissolves with orange brown, un color and after-chrome-plated wool gives it a bluish red tint.
Example: 22.4 parts of 6-nitro-2-amino-4-tert-amyl phenol are dissolved with 4.1 parts of sodium hydroxide in 200 parts of water, 6.9 parts of sodium nitrite in 35 parts of water are added and the mixture is added a 3 not exceed the temperature to 35 parts by volume conc. Hydrochloric acid was added dropwise to 100 parts of water.
So he keeps a yellowish green suspension of the I) iazo body. After the end of the diazotization, the acidity of the diazo suspension is blunted with sodium bicarbonate to kongoneutral, whereupon a solution of 33.5 parts of 1- (4'-chlorophenyl) -5-py razolon-4-carboxylic acid niethylamide-5'-sulfonic acid amide and 8 parts of sodium hydroxide in 100 parts of 0-3 water is added.
The reaction mixture is made 25% weakly alkaline to phenolphthalein with 10 parts of ammonia. Then the temperature is allowed to rise slowly from 3 to 20. The coupling is over after about 20 hours. The precipitated dye is filtered off, washed with 21 / / o brine and dried.
The dye is a dark, violet powder that turns blue-red in hot water, in conc. Sulfuric acid with an orange brown color dozes. For use, the product is ground well with a little sodium carbonate and a dispersing agent. The dye dyes wool from an acidic bath with a yellow-brown hue, which turns into a bluish red when chromium-plating.
With the single-bath chrome process, dyeings of the same shade and thickness, with very good wet and light fastness properties, are obtained with little or no addition of acid and with complete exhaustion of the dye bath.
The above-mentioned pyrazolone is obtained, for. B. by converting 4-chloro-anilline-5 sulfonic acid amide according to known methods into the corresponding hydrazine and this hydrazine with ethyl sodium oxaloacetate to form 1- (4'-chlorophenyl) -5-pyrazolone-3-carboxylic acid ethyl ester - 5 '- sulfonic acid amide condensed.
The ethyl pyrazolone-3-carboxylate obtained is then suspended in about five times the amount of 25% methylamine and either left to stand at 20 for 2-4 days or heated to 80 to 100 for 10-15 hours in a pressure vessel. The pyrazolone-3-carboxylic acid ester goes into solution, the alcohol residue of the ester is split off and replaced by the amide residue.
