<B>Zusatzpatent</B> zum Hauptpatent Nr. 296669. Verfahren zur Herstellung eines sauren Wollfarbstoffes. Gegenstand dieses Patentes ist ein Verfah ren zur Herstellung eines sauren Wollfarb- stoffes, welches darin besteht,
dass man 1 Mol der durch Kondensation von 1 Mol 4.4'-Di- chlorbenzophenon mit 1 Mol N-Methyl-2-phe- nylindol erhältlichen Verbindung mit 2 Mol 1-Amino-4-phenoxybenzol-3-sulfonsäure um setzt.
Die Umsetzung erfolgt durch Erhitzen der Ausgangsstoffe mit oder ohne Zusatz von Lö- sungs- oder Schmelzmitteln, z. B. unter Zusatz von Glykol oder ähnlichen Verbindungen. Man kann zum Beispiel Temperaturen von 110 bis 160 C anwenden. Die 1-Amino-4-phenoxyben- zol-3-sulfonsäure wird als freie Säure oder in Form ihrer Alkali- oder Ammoniumsalze ver wendet.
Der neue Farbstoff färbt Wolle in sehr klaren blauen Tönen von guter Lichtechtheit und schöner Abendfarbe. Er besitzt ein gutes Egalisierungsvermögen, gutes Ziehvermögen aus saurem und neutralem Bade sowie gute Seewasser- und Schweissechtheit.
<I>Beispiel:</I> 251 g 4.4'-Dichlorbenzophenon und 207 g N-Methyl-2-phenylindol werden in 1800 cm3 Chlorbenzol bei 70 C gelöst und unter Zusatz von 160 g wasserfreiem Zinkchlorid und 306 g Phosphoroxy Chlorid 18 Stunden bei 120 bis 125 C verrührt.
Nach dem Abkühlen werden die entstandenen rotbraunen Kristalle abge saugt, mit kaltem Chlorbenzol gewaschen und getrocknet. Die so erhaltene rote Kondensa tionsverbindung ist an sich stark farbig, hat aber noch keinen Farbstoffcharakter; sie ist in konzentrierter Schwefelsäure mit tief rot- braimer und in Eisessig mit gelbbrauner Farbe löslich.
20 g dieser Verbindung werden mit 100 g Glykol und 40 g des Natriumsalzes der 1- Amino-4-phenoxybenzol-3-sulfonsäure 4 bis 6 Stunden bei 120 bis 130 C verrührt, bis die Farbstoffbildung nicht mehr zunimmt. Beim Ausgiessen in Wasser scheidet sich ein blauer Farbstoff ab, der abgesaugt und durch Aus waschen mit wenig kaltem Wasser gereinigt wird.
Er wird in warmem Wasser unter Zu satz der hinreichenden Menge Natriumcarbo- nat gelöst, die Lösung wird filtriert, mit 20 bis 25 g eines Dispergierungsmittels versetzt, und aus der Lösung wird dann durch Aus salzen mit Natriumchlorid der Farbstoff ab geschieden. Er stellt das Natriumsalz einer einheitlichen Disulfonsäure von folgender Zu sammensetzung dar
EMI0002.0001
Der neue Farbstoff färbt Wolle in sehr klaren blauen Tönen von guter Lichtechtheit und schöner Abendfarbe.
Er besitzt ein gutes Egalisierungsvermögen, gutes Ziehvermögen aus saurem und neutralem Bade sowie gute Seewasser- und Schweissechtheit; er besitzt ferner praktisch keine Affinität zur Baum wollfaser und liefert daher auf Mischgeweben aus Wolle und Baumwolle Färbungen mit rei nen Baumwolleffekten.
<B> Additional patent </B> to main patent no. 296669. Process for the production of an acidic wool dye. The subject of this patent is a process for the production of an acidic wool dye, which consists of
that 1 mol of the compound obtainable by condensation of 1 mol of 4,4'-dichlorobenzophenone with 1 mol of N-methyl-2-phenylindole is reacted with 2 mol of 1-amino-4-phenoxybenzene-3-sulfonic acid.
The reaction takes place by heating the starting materials with or without the addition of solvents or fluxes, eg. B. with the addition of glycol or similar compounds. For example, temperatures from 110 to 160 ° C can be used. The 1-amino-4-phenoxyben- zene-3-sulfonic acid is used as the free acid or in the form of its alkali metal or ammonium salts.
The new dye dyes wool in very clear blue shades of good lightfastness and a beautiful evening color. It has good leveling properties, good drawability from acidic and neutral baths and good fastness to sea water and perspiration.
<I> Example: </I> 251 g of 4,4'-dichlorobenzophenone and 207 g of N-methyl-2-phenylindole are dissolved in 1800 cm3 of chlorobenzene at 70 ° C. and with the addition of 160 g of anhydrous zinc chloride and 306 g of phosphorus oxychloride for 18 hours Stirred at 120 to 125 C.
After cooling, the resulting red-brown crystals are filtered off with suction, washed with cold chlorobenzene and dried. The red condensation compound obtained in this way is strongly colored per se, but does not yet have the character of a dye; it is soluble in concentrated sulfuric acid with a deep red-brown color and in glacial acetic acid with a yellow-brown color.
20 g of this compound are stirred with 100 g of glycol and 40 g of the sodium salt of 1-amino-4-phenoxybenzene-3-sulfonic acid for 4 to 6 hours at 120 to 130 ° C. until the formation of the dye no longer increases. When pouring into water, a blue dye is deposited, which is sucked off and cleaned by washing with a little cold water.
It is dissolved in warm water with the addition of a sufficient amount of sodium carbonate, the solution is filtered, 20 to 25 g of a dispersing agent are added, and the dye is then separated from the solution by salting it out with sodium chloride. It is the sodium salt of a uniform disulfonic acid with the following composition
EMI0002.0001
The new dye dyes wool in very clear blue shades of good lightfastness and a beautiful evening color.
It has good leveling properties, good drawability from acidic and neutral baths, and good fastness to sea water and perspiration; Furthermore, it has practically no affinity for cotton fibers and therefore provides dyes with pure cotton effects on blended fabrics made of wool and cotton.
