Description
Verfahren zur Herstellung eines neuen Azofarbstoifes. Es wurde gefunden, dass man einen neuen Farbstoff erhält, wenn man diazotiertes 2,4- Dichloranilin mit 1(2-Chlor-5-siilfo)-phenyl-3- methyl-5-pyrazolon kuppelt.
Der neue Farbstoff bildet ein gelbes Pul ver, er löst sich in Wasser mit gelber Farbe und ist zum Färben von Wolle und Seide geeignet. Er zeichnet sich durch sehr gutes Egalisierungsvermögen, sehr gute Lichtecht heit und gute Wasch-, Säure- und Walk- echtheit seiner Färbungen aus. Der neue Farbstoff kann auch in unlösliche Metallsalze übergeführt werden und als Lack Verwen dung finden.
<I>Beispiel:</I> <B>16,2</B> Teile 2,4-Dichloranilin werden wie üblich diazotiert. Bei 5-I0 wird diese Diazo- lösung mit einer überschüssiges Natriumcar- bonat enthaltenden Lösung von 28,8 Teilen l(2 - Chlor - 5 - sulfo)-phenyl-3-methyl-5-pyrazo- lon vereinigt. Die Kupplung setzt sofort ein. Man rührt bis zum Verschwinden der Diazo- verbindung, filtriert den ausgefällten Farb stoff und trocknet ihn.
Process for the production of a new azo dye. It has been found that a new dye is obtained when diazotized 2,4-dichloroaniline is coupled with 1 (2-chloro-5-silfo) -phenyl-3-methyl-5-pyrazolone.
The new dye forms a yellow powder, it dissolves in water with a yellow color and is suitable for dyeing wool and silk. It is characterized by very good leveling properties, very good lightfastness and good wash, acid and milled fastness of its dyeings. The new dye can also be converted into insoluble metal salts and used as a varnish.
<I> Example: </I> <B> 16.2 </B> parts of 2,4-dichloroaniline are diazotized as usual. At 5-10 this diazo solution is combined with a solution containing excess sodium carbonate of 28.8 parts of 1 (2-chloro-5-sulfo) -phenyl-3-methyl-5-pyrazolone. The clutch works immediately. The mixture is stirred until the diazo compound disappears, the precipitated dye is filtered off and dried.
