Description

  

      Zusatzpatent    zum Hauptpatent Nr.     163539.       Verfahren zur Herstellung eines neuen     Azofarbstoifes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man dianotiertes       2-Clilor-4-riitranilin    mit     [ss-(2-Methoxy-5-          methyl)    -     phenylamirio]        äthyluiethyläther    ver  einigt.  



  Der neue     Farbstoff    bildet ein dunkles  Pulver, das in Wasser unlöslich ist, sich da  gegen in Essigester leicht mit blauroter Farbe  löst. Er färbt     Aoetatseide    in blauroten Tönen.  <I>Beispiel:</I>  17,25 Teile     2-Chlor-4-nitranilin    werden  mit Wasser vermahlen und mit 25 Teilen  konzentrierter Salzsäure und 7 Teilen Na  triumnitrit unter Zusatz von Eis dianotiert.  Die erhaltene     Diazolösung    lässt man zu einer  Lösung von 19,5 Teilen     [ss-(2-Methoxy-5-nie=          thyl)    -     phenylamirio]        äthslmethyläther    in ver-    dünnten Salzsäure zufliessen.

   Dann versetzt  man langsam mit     Natriumacetatlösung    bis  die Kupplung beendet ist. Der Farbstoff  scheidet sich als dunkles Pulver aus.



      Additional patent to main patent no. 163539. Process for the production of a new azo dye. It has been found that a new azo dye is obtained if dianotated 2-chloro-4-riitraniline is combined with [ss- (2-methoxy-5-methyl) phenylamirio] ethyl ethyl ether.



  The new dye forms a dark powder that is insoluble in water, whereas it dissolves easily with a bluish red color in ethyl acetate. He dyes acetate silk in blue-red tones. <I> Example: </I> 17.25 parts of 2-chloro-4-nitroaniline are ground with water and dianotized with 25 parts of concentrated hydrochloric acid and 7 parts of sodium nitrite with the addition of ice. The diazo solution obtained is allowed to flow into a solution of 19.5 parts of [ss- (2-methoxy-5-nie = thyl) - phenylamirio] ethyl ether in dilute hydrochloric acid.

   Sodium acetate solution is then slowly added until the coupling has ended. The dye separates out as a dark powder.
