Description

  

  Verfahren zur     Rerstellung    eines neuen     Azofarbstoffes.       Es wurde gefunden,     #dass,    man einen neuen       Azofarbstoff    erhält, wenn man das     diazo-          tierte        Diät)lylamid    der     2-Aminobenzoesä.ure     mit dem     2,#3-Oxynaplithopsäure-2'-met'hylani-          lid    vereinigt.  



  Der neue Farbstoff bildet ein     lebhauft    ge  färbtes     oranges    Pulver. Auf geeigneten Sub  straten, wie zum Beispiel Baumwolle, her  gestellt, färbt er diese in echten orangen  Tönen.  



  <I>Beispiel:</I>  <B>19,1</B> Teile des     Diätliylamids    der     2.-Ami-          nobenzoesäure    werden wie     übliell        diazotiert     und in eine Lösung von<B>27,7</B> Teilen     2,3-Oxy-          napht'hoesä,ure   <B>-</B>     2'-        metllylanilid,    40 Teilen  30%iger     Natriumhydraxydlösung,   <B>15</B> Teilen    Soda und<B>1000</B> Teilen Wasser eingetragen.  Der gebildete Farbstoff fällt sofort aus. Der  orange Niederschlag wird filtriert     und    ge  trocknet.



  Process for the preparation of a new azo dye. It has been found that a new azo dye is obtained when the diazo-tated diet) lylamide of 2-aminobenzoic acid is combined with 2, # 3-oxynaplithopic acid-2'-methylanilide.



  The new dye forms a brightly colored orange powder. Produced on suitable substrates, such as cotton, he dyes them in real orange tones.



  <I> Example: </I> <B> 19.1 </B> parts of the diethylamide of 2.-aminobenzoic acid are diazotized as usual and converted into a solution of <B> 27.7 </B> parts of 2 , 3-Oxynapht'hoesä, ure <B> - </B> 2'- metllylanilid, 40 parts of 30% sodium hydroxide solution, <B> 15 </B> parts of soda and <B> 1000 </B> parts Water entered. The dye formed precipitates immediately. The orange precipitate is filtered and dried.
