Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man     diazotiertes          1-Amino-4-(f,        r-dioxy)        propyloxybenzol    mit       1,3-Diaminobecizol-4-sul    Tonsäure vereinigt. Der  neue     Farbstoff    bildet ein dunkelbraunes Pul  ver, das sich in Wasser mit brauner Farbe  löst. Es färbt Leder in     grünstichig-braunen     Tönen vollständig durch.  



  <I>Beispiel:</I>  18,3 Teile     1-Amino-4-(ss,        r-dioxy)        propyl-          oxybenzol    werden in verdünnter Salzsäure  gelöst und unter Zusatz von 6,9 Teilen Na  triumnitrit     diazotiert.    Die klare     Diazolösung     vereinigt man bei<B>5-101</B> mit einer Lösung  von 18,8 Teilen 1,3-Diaminobeuzol-4-sulfon-    säure in 300 Teilen Wasser und 30 Teilen       Natriumcarbonat.     



  Nach Beendigung der     Farbstoffbildung     wird aufgewärmt und     ausgesalzen.  



  Process for the production of a new azo dye. It has been found that a new azo dye is obtained when diazotized 1-amino-4- (f, r-dioxy) propyloxybenzene is combined with 1,3-diaminobecizol-4-sulphonic acid. The new dye forms a dark brown powder that dissolves in water with a brown color. It completely dyes leather in greenish brown tones.



  <I> Example: </I> 18.3 parts of 1-amino-4- (ss, r-dioxy) propyl oxybenzene are dissolved in dilute hydrochloric acid and diazotized with the addition of 6.9 parts of sodium nitrite. The clear diazo solution is combined at 5-101 with a solution of 18.8 parts of 1,3-diaminobeuzene-4-sulfonic acid in 300 parts of water and 30 parts of sodium carbonate.



  After the dye has formed, it is warmed up and salted out.
