Description

  

  Verfahren zur Herstellung eines Substantiven     Azofarbstoffes.       Gegenstand des vorliegenden Zusatz  patentes ist ein Verfahren zur Herstellung  eines Substantiven     Azofarbstoffes,        dadureh     gekennzeichnet,

   dass man     diazotiertes        1-Oxy--          2-Aminobenzol-4-earbonsäure-phenylamid    mit       2-Phenylamino    - 5 -     oxynaphthalin    - 7 -     sulfon-          säure    in alkalischem Medium vereinigt und  den neuen Farbstoff durch     Behandeln    mit       kupferabgebenden        Mitteln    in eine komplexe       Kupferverbindung    überführt. Diese färbt  Baumwolle in echten rotvioletten Tönen.  



       Beispiel:     22,8     Gewichtsteile        1-Oxy-2-aminobenzol-          4-carbonsäurephenylamid    werden unter Zu  satz von 6,9 Gewichtsteilen     Natriumnitrit     und 27 Gewichtsteilen konzentrierter Salz  säure bei 0      diazotiert    und die     Diazoverbin-          dung    mit<B>31,5</B> Gewichtsteilen     2-Phenylamino-          5-oxynaphthalin-7-sulfonsäure,

      die als     Na.-          trzumsalz        unter    Zusatz von 100 Gewichts  teilen 20 %     igem        Calciumhydroxyd    in 1000 Ge  wichtsteilen     Wasser    gelöst wurden, vereinigt.

    Nach 4     Stunden    wird der gebildete Farb-         stoff    durch     Zusatz        voll    Salzsäure abgeschie  den und     filtriert.    Der     Filterrückstand        wird          in    bekannter Weise durch Behandeln mit       einer        Lösung    von 25     Gewichtsteilen        kristal-          lisiertem        Kupfersulfat    in 100 Gewichtsteilen  25%igem Ammoniak in 1000 Gewichtsteilen       Wasser    bei 35-40  in seine Kupferverbin  dung 

  übergeführt. Die     gebildete    Kupferver  bindung fällt aus, wird filtriert und getrock  net. Der neue Farbstoff bildet     ein        dunkles     Pulver, das Baumwolle in echten     rotvioletten     Tönen färbt.



  Process for the production of a noun azo dye. The subject of the present additional patent is a process for the production of a noun azo dye, dadureh,

   that diazotized 1-oxy- 2-aminobenzene-4-carboxylic acid-phenylamide is combined with 2-phenylamino-5-oxynaphthalene-7-sulfonic acid in an alkaline medium and the new dye is converted into a complex copper compound by treatment with copper-releasing agents. This dyes cotton in real red-violet tones.



       Example: 22.8 parts by weight of 1-oxy-2-aminobenzene-4-carboxylic acid phenylamide are diazotized at 0 with the addition of 6.9 parts by weight of sodium nitrite and 27 parts by weight of concentrated hydrochloric acid and the diazo compound with <B> 31.5 </ B> parts by weight of 2-phenylamino-5-oxynaphthalene-7-sulfonic acid,

      which were dissolved as sodium trzumsalz with the addition of 100 parts by weight of 20% calcium hydroxide in 1000 parts by weight of water, combined.

    After 4 hours, the dyestuff formed is separated off by adding hydrochloric acid and filtered. The filter residue is converted into its copper compound in a known manner by treatment with a solution of 25 parts by weight of crystallized copper sulfate in 100 parts by weight of 25% strength ammonia in 1000 parts by weight of water at 35-40

  convicted. The formed copper compound precipitates, is filtered and net getrock. The new dye forms a dark powder that dyes cotton in true red-purple tones.
