Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man     diazotiertes          2.4-Dinitranilin    mit     [P-(2.5-Dimethoxy)-          phenylamizio]äthylmethyläther    vereinigt.  



  Der neue     Farbstoff    bildet ein dunkles  Pulver, das in Wasser unlöslich ist, sich  dagegen in Essigester leicht mit violetter  Farbe löst. Er färbt     Acetatseide    in violetten  Tönen.  



  <I>Beispiel:</I>  18,3 Teile     2.4-Dinitranilin    werden in  eine aus 50 Teilen Schwefelsäure 66       B6    und  8 Teilen     Natriumnitrit    hergestellte Lösung  von     Nitrosylschwefelsäure    eingerührt. Die       Diazotierung    ist beendet, wenn eine Probe  sich in Eiswasser klar löst. Nun giesst man  Wasser und Eis. Die erhaltene     Diazolösung     lässt man zu einer Lösung von 21,1 Teilen       [p    -<B>(2.5</B> -     Dimethoxy)    -     phenylamino]    äthyl-         methyläther    in verdünnter Salzsäure zufliessen.

    Dann versetzt man langsam mit Natrium  acetatlösung bis die Kupplung beendet ist.  Der     Farbstoff    scheidet sich als violettes  Pulver aus.



  Process for the production of a new azo dye. It has been found that a new azo dye is obtained if diazotized 2,4-dinitraniline is combined with [P- (2,5-dimethoxy) phenylamizio] ethyl methyl ether.



  The new dye forms a dark powder that is insoluble in water, but dissolves easily with a purple color in ethyl acetate. He dyes acetate silk in purple tones.



  <I> Example: </I> 18.3 parts of 2,4-dinitraniline are stirred into a solution of nitrosylsulfuric acid prepared from 50 parts of sulfuric acid 66 B6 and 8 parts of sodium nitrite. The diazotization is over when a sample dissolves clearly in ice water. Now you pour water and ice. The diazo solution obtained is allowed to flow into a solution of 21.1 parts of [p - (2.5) - dimethoxy) - phenylamino] ethyl methyl ether in dilute hydrochloric acid.

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