Description

  

  Verfahren zur Herstellung eines     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen  wertvollen     Azofarbatoff        aerhält,    wenn man       8-Oxychinaldin    mit der     Diazoverbindung    der       1-Aminobei)zol-3-sulfonaäure    kuppelt.  



  Der Farbstoff kann mit Vorteil als     Nach-          chromierfarbstoff    verwendet oder in Substanz  in komplexe Metallverbindungen übergeführt       werdet).    Auch kann man ihn zum Färben  nach dem sogenannten     Einbadverfahren    be  nutzen.  



  <I>Beispiel:</I>  Man     diazotiert    17,3 Teile     1-Aminobenzol-          3-sulfonaäure    und lässt die erhaltene Lösung  der     Diazoverbindung    zu einer salzsauren Lö  sung von 17,4 Teilen     8-Oxychinaldin    fliessen.  Durch Zugabe von     Natriumacetat    wird die  Kupplung zu Ende geführt. Der Farbstoff  liefert auf Wolle orange Färbungen; beim    Nachbehandeln mit     Bichromat    ändert sich  der Farbton kaum, und man erhält -eine.  echte orange Färbung. ,



  Process for the preparation of an azo dye. It has been found that a new valuable azo carbate is obtained when 8-oxychinaldine is coupled with the diazo compound of 1-amino-3-phenol-3-sulfonic acid.



  The dye can be used with advantage as a post-chromium dye or can be converted into complex metal compounds as it is. You can also use it for dyeing according to the so-called single bath process.



  <I> Example: </I> 17.3 parts of 1-aminobenzene-3-sulfonic acid are diazotized and the resulting solution of the diazo compound is allowed to flow into a hydrochloric acid solution of 17.4 parts of 8-oxychinaldine. The coupling is completed by adding sodium acetate. The dye produces orange dyes on wool; after treatment with bichromate, the color hardly changes, and you get -ein. true orange color. ,
