Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es     wurde    gefunden, dass man einen  neuen     Azofarbstoff    erhält, wenn man     di-          azotiertes        2.6-Dichlor-4-nitro-l-aminobenzol     mit     Athyl-(c)-acetoxäthyl)-anilin    vereinigt.  



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



  <I>Beispiel:</I>  20,7 Teile     2.6-Diehlor-4-ni+,ro-l-amino-          benzol    werden in eine aus 50 Teilen Schwe  felsäure 66       B6    und 8     Teilen        Natriumnitrit          hergestellte    Lösung von     Nitrosylschwefel-          säure    eingerührt. Die     Diazotierung    ist be  endet, wenn sich eine Probe in Eiswasser  klar löst. Man giesst auf Wasser und Eis.

    Die so erhaltene     Diazolösung        lässt    man zu  einer Lösung von 20,7 Teilen Äthyl-(co-         acetoxäthyl)-anilin    in     verdünnter    Salzsäure  zufliessen. Dann versetzt man langsam mit       Natriumacetatlösung,    bis die Kupplung be  endet ist. Der Farbstoff scheidet sich als  dunkles Pulver aus.



  Process for the production of a new azo dye. It has been found that a new azo dye is obtained if diazotized 2,6-dichloro-4-nitro-1-aminobenzene is combined with ethyl- (c) -acetoxyethyl) aniline.



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



  <I> Example: </I> 20.7 parts of 2,6-diehlor-4-ni +, ro-1-aminobenzene are stirred into a solution of nitrosylsulfuric acid prepared from 50 parts of sulfuric acid 66 B6 and 8 parts of sodium nitrite. Diazotization is over when a sample dissolves clearly in ice water. You pour on water and ice.

    The diazo solution obtained in this way is allowed to flow into a solution of 20.7 parts of ethyl (co-acetoxethyl) aniline in dilute hydrochloric acid. Sodium acetate solution is then added slowly until the coupling has ended. The dye separates out as a dark powder.
