Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden,     dass    man einen neuen       Azofarbstoff    erhält, wenn man     diazotiertes          1-Aminophenyl-3-beiizyl8ulfoii    mit     2,3-Oxy-          naphthoesäure-anilid    vereinigt. Der so erhal  tene Farbstoff bildet ein orange gefärbtes,  in Wasser     unlöslichesPulver.    Auf geeigneten  Substraten, wie zum Beispiel Zellulose, her  gestellt, färbt er diese in leuchtend orangen  Tönen.  



  <I>Beispiel:</I>  24,7 Teile     1-Aminophenyl-3-benzylsulfon     (das erhalten wird durch Kondensieren der       1-Nitrobenzol-3-sulfinsäure    mit     BenzirIch16rid     und Reduktion des entstandenen     'Sulfons)     werden wie üblich     diazotiert    und in eine  Lösung von<B>26,3</B> Teilen     2,3-Oxynaphthoe-          säure-anilid,   <B>50</B> Teilen<B>80</B> %     iger    Natronlauge,    <B>15</B> Teilen Soda und 2000 Teilen Wasser ein  getragen. Der gebildete Farbstoff fällt sofort  aus. Der orange Niederschlag wird filtriert  und getrocknet.



  Process for the production of a new azo dye. It has been found that a new azo dye is obtained if diazotized 1-aminophenyl-3-beiicyl8ulfoii is combined with 2,3-oxynaphthoic acid anilide. The dye thus obtained forms an orange colored, water-insoluble powder. Produced on suitable substrates such as cellulose, he dyes them in bright orange tones.



  <I> Example: </I> 24.7 parts of 1-aminophenyl-3-benzylsulfone (which is obtained by condensing the 1-nitrobenzene-3-sulfinic acid with benziric chloride and reducing the sulfone formed) are diazotized as usual and converted into a Solution of <B> 26.3 </B> parts of 2,3-oxynaphthoic acid anilide, <B> 50 </B> parts of <B> 80 </B>% sodium hydroxide, <B> 15 </ B> parts of soda and 2000 parts of water. The dye formed precipitates immediately. The orange precipitate is filtered and dried.
