Description
Verfahren zur Darstellung eines CLromierungsfarbstoffes. Es wurde gefunden, dass man sehr echte, chromierfähige Farbstoffe erhalten kann, wenn man eine Oxytrimellithsäure oder deren Anhydrid mit solchen aromatischen Verbin dungen in Gegenwart oder Abwesenheit von Kondensationsmitteln kondensiert, welche eine reaktionsfähige Methyl- oder Methylen- gruppe enthalten, wie zum Beispiel Chinal- dine, 2-Methylarylimidazole,
2-Methylaryl- oxazole, 2-Methylarylthiazole, 2-Methylen- indoline und dergl. und deren Derivate und Substitutionsprodukte, und die erhaltenen Produkte mit sulfierenden Mitteln behandelt.
Als Oxytrimellithsäure kommen in Frage die 5 - Oxybenzol -1,2,4 - tricarbonsäure, die zum Beispiel nach dem Verfahren unseres Schweizer Patentes Nr. 196843 hergestellt werden kann, und die 3-Oxybenzol-1,2,4-tri- carbonsäure, die zum Beispiel durch Bromie- ren von Pseudocumol-5-sidfosäure in konzen trierter Schwefelsäure, Abspalten der Sulfo- gruppe, Oxydation und Ersatz des Brom- atoms gegen die Hydroxylgruppe erhältlich ist.
Die neuen Farbstoffe färben - sauer ge färbt - die tierische Faser in gelben Tönen sehr egal an und besitzen nach dem Chromie- ren sehr gute Echtheitseigenschaften.
Gegenstand des Patentes ist ein Verfah ren zur Darstellung eines Chromierungsfarb- stoffes, welches dadurch gekennzeichnet ist, dass man 5-Oxybenzol-1,2,4-tricarbonsäurean- hydrid mit Chinaldin kondensiert und das so erhaltene Produkt mit einem sulfierend wir kenden Mittel behandelt.
<I>Beispiel:</I> 4 Gewichtsteile 5-Oxybenzol-1,2,4-tricar- bonsäureanhydrid oder die entsprechende Menge der freien Säure, 3 Gewichtsteile Chinaldin, 1 Gewichtsteil wasserfreies Zink chlorid werden zusammen auf 180 bis 190 C erhitzt. Die Schmelze gerät in gelindes Schäumen und wird allmählich fest. Nach vollständigem Erstarren lässt man abkühlen und kocht die fein pulverisierte Schmelze mit der etwa 50fachen Menge 5%iger Salzsäure aus. Der abgesaugte Rückstand wird neutral gewaschen und getrocknet. Zur weiteren Rei nigung wird aus Chinolin heiss umgelöst.
Man erhält eine reingelbe kristalline Sub stanz, die in Bicarbonatlösung mit gelber Farbe, in verdünnter Natronlauge dagegen mit orangeroter Farbe, löslich ist.
1 Gewichtsteil dieser Substanz wird mit 3 Gewiehtsteilen 30 % igem Oleum zwei Stun den auf 60 C. dann so lange auf 100 C erhitzt, bis eine Probe in heissem Wasser klar löslich ist. Man giesst dann auf Eis, saugt den gelben Niederschlag ab und wäscht ihn mit Nasser so lange, bis der Ablauf sich kräftig gelb färbt. Der Niederschlag wird dann so lange mit gesättigter Bicarbonat- lösung verrührt, bis neutrale Reaktion ein getreten ist. Die so erhaltene Paste des Farb stoffes wird auf dem Wasserbad zur Trockne gedampft.
Man erhält so einen gelben Farb stoff, der aus saurem Bade die tierische Faser sehr gleichmässig gelb färbt und nach- chromiert ausgezeichnete Echtheitseigenschaf ten besitzt. Der Farbstoff ist eine Mouo- sulfosäure.
Process for the preparation of a chromating dye. It has been found that very real, chromable dyes can be obtained if an oxytrimellitic acid or its anhydride is condensed with such aromatic compounds in the presence or absence of condensing agents which contain a reactive methyl or methylene group, such as quinine dine, 2-methylarylimidazole,
2-methylaryl oxazoles, 2-methylarylthiazoles, 2-methylene indolines and the like. And their derivatives and substitution products, and the products obtained are treated with sulfonating agents.
Suitable oxytrimellitic acid are 5-oxybenzene-1,2,4-tricarboxylic acid, which can be prepared, for example, according to the process of our Swiss patent No. 196843, and 3-oxybenzene-1,2,4-tricarboxylic acid, which can be obtained, for example, by brominating pseudocumene-5-sifoic acid in concentrated sulfuric acid, splitting off the sulfo group, oxidizing and replacing the bromine atom with the hydroxyl group.
The new dyes - dyed with acid - dye the animal fibers in yellow tones very irrespective of the color and have very good fastness properties after chromizing.
The subject of the patent is a process for the preparation of a chromating dye, which is characterized in that 5-oxybenzene-1,2,4-tricarboxylic anhydride is condensed with quinaldine and the product thus obtained is treated with a sulphurizing agent.
<I> Example: </I> 4 parts by weight of 5-oxybenzene-1,2,4-tricarboxylic acid anhydride or the corresponding amount of the free acid, 3 parts by weight of quinaldine, 1 part by weight of anhydrous zinc chloride are heated together to 180 to 190 ° C. The melt begins to foam slightly and gradually solidifies. After it has completely solidified, it is allowed to cool and the finely powdered melt is boiled with about 50 times the amount of 5% hydrochloric acid. The suction filtered residue is washed neutral and dried. For further cleaning, quinoline is redissolved hot.
A pure yellow crystalline substance is obtained which is soluble in bicarbonate solution with a yellow color, but in dilute sodium hydroxide solution with an orange-red color.
1 part by weight of this substance is heated with 3 parts by weight of 30% oleum for two hours at 60 ° C. and then heated to 100 ° C. until a sample is clearly soluble in hot water. It is then poured onto ice, the yellow precipitate is filtered off with suction and washed with water until the effluent turns a bright yellow color. The precipitate is then stirred with saturated bicarbonate solution until a neutral reaction has occurred. The paste of the dye thus obtained is evaporated to dryness on a water bath.
The result is a yellow dye which, from an acid bath, dyes the animal fibers yellow very evenly and, when chromated, has excellent fastness properties. The dye is a mouosulfonic acid.
