Description
Zusatzpatent zum Hauptpatent Nr. 296669. Verfahren zur Herstellung eines sauren Wollfarbstoffes. Gegenstand dieses Patentes ist ein Ver fahren 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-Metliyl-2-phe- nylindol erhältlichen Verbindung mit 2 Mol 1-Amino-4-äthoxybenzol-2-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-äthoxyben- zol-2-siilfonsäure wird als freie Säure oder in Form ihrer Alkali- oder Ammoniumsalze ver wendet.
Der neue Farbstoff färbt Wolle in sehr klaren blauen Tönen von gilter Liehtechtheit und schöner Abendfarbe. Er besitzt ein gutes Egalisierungsvermögen, gutes Ziehvermögen aus saurem und neutralem Bade sowie gute Seewasser- und Schweissechtheit.
<I>Beispiel:</I> 30 g der durch Kondensation von 4.4!-Di- chlorbenzophenon und N-Methyl-2-phenylindol erhältlichen Verbindung werden mit 60 g des Natrium-, Kalium- oder Ammoniumsalzes der 1-Amino-4-äthoxybenzol-2-sulfonsäure unter Zusatz von 200-g Glykol 4 bis 7 Stunden auf 140 bis 155 C erwärmt, bis die Farbstoffbil- dung nicht mehr zunimmt.
Die beim Ausgie ssen in Wasser ausfallende Farbstoffdisulfon- säure wird abfiltriert, durch Auswaschen mit kaltem Wasser gereinigt, dann in warmem Wasser unter Zilsatz der hinreichenden Menge Natriinncarbonat gelöst, die Lösung wird mit 10 bis 15 g eines geeigneten Netzmittels ver setzt und aus der Lösung dann der Farbstoff durch Natriumchlorid gefällt.
Der so erhal tene Farbstoff stellt das Mononatriumsalz einer Farbstoffdisulfonsäure von folgender Zusammensetzung 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.
Additional patent 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 in that 1 mol of the by condensation of 1.
Mol of 4,4'-dichlorobenzophenone with 1 mol of N-methyl-2-phenylindole available compound with 2 mol of 1-amino-4-ethoxybenzene-2-sulfonic acid sets.
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. 1-Amino-4-ethoxybenzene-2-silfonic 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 tones with good light fastness 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> 30 g of the compound obtainable by condensation of 4.4! -Dichlorobenzophenone and N-methyl-2-phenylindole are mixed with 60 g of the sodium, potassium or ammonium salt of the 1-amino-4- Ethoxybenzene-2-sulfonic acid with the addition of 200 g of glycol is heated to 140 to 155 ° C. for 4 to 7 hours until the formation of dye no longer increases.
The dyestuff disulfonic acid which precipitates out when pouring into water is filtered off, cleaned by washing out with cold water, then dissolved in warm water using a sufficient amount of sodium carbonate, the solution is mixed with 10 to 15 g of a suitable wetting agent and then removed from the solution the dye is precipitated by sodium chloride.
The dye obtained in this way is the monosodium salt of a dye 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 dyeings with pure cotton effects on blended fabrics made of wool and cotton.
