Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man     diazotiertes        2,4-          Dichloranilin    mit     l(4-Chlor-3-sulfo)-phenyl-3-          rnethyl-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>  16,2 Teile     2,4-Dichloranilin    werden wie  üblich     diazotiert.    Bei     5-10     wird diese     Diazo-          lösung    mit einer überschüssiges     Natriumcar-          bonat    enthaltenden Lösung von 28,8 Teilen  l(4 - Chlor -     3-sulfo)    -     phenyl-3-methyl-5-pyrazo-          lon    vereinigt. Die Kupplung tritt 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 (4-chloro-3-sulfo) -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> 16.2 parts of 2,4-dichloroaniline are diazotized as usual. At 5-10, this diazo solution is combined with a solution of 28.8 parts of 1 (4-chloro-3-sulfo) -phenyl-3-methyl-5-pyrazolone containing excess sodium carbonate. The clutch occurs immediately. The mixture is stirred until the diazo compound disappears, the precipitated dye is filtered off and dried.
