Description

  

      Zusatzpatent    zum Hauptpatent Nr. 200369.    Verfahren zur Herstellung eines     Nüpenfarbstoffes.       Vorliegendes Patent bezieht sich auf ein       Verfahren:    zur     Herstellung        eines        Küpenfarb-          stoffes,    dadurch gekennzeichnet,     dass    man  ein funktionelles Derivat     ,der        Azobenzol-3    .

       5-          diearbonsäure    mit     l@Ami.no-5-benzoylamino-          anthTachinon        im.        Molekularverhältnis    1:2       kondensiert.     



  Der so erhaltene     Farbstoff    färbt Baum  wolle aus     violetter        güpe    in sehr echten gel  ben Tönen.  



  <I>Beispiel:</I>  31 Teile     Azobenzol-3.        5-dicarbonsäure-di-          chlorid,    das beispielsweise durch Kondensa  tion von     Nitrosobenzol    mit     5-Amino-isophthal-          säure    und Behandlung der so erhaltenen       Dicarbonsäure    mit     Thionylchloridhergestellt     werden kann und das     nach    dem     Umkristalli-          sieren        aus        Benzin.    :

  den     Schmelzpunkt    121   C       zeigt,    werden in     o-Dichlorbenzol        durch    mehr-         ständiges    Erhitzen mit 70     Teilen        1-Amino-          Zi-benzoylamiuoanthrachinon    kondensiert. Der       gebildete        Farbstoff        wird    dann abgesaugt,     ,ge-          waschen    und     getrocknet.  



      Additional patent to main patent no. 200369. Process for the production of a pebble dye. The present patent relates to a process: for the production of a vat dye, characterized in that a functional derivative, the azobenzene-3.

       5- diacid with l@Ami.no-5-benzoylamino-anthTachinon im. Molecular ratio 1: 2 condensed.



  The dye obtained in this way dyes cotton from violet güpe in very real yellow tones.



  <I> Example: </I> 31 parts of azobenzene-3. 5-dicarboxylic acid dichloride, which can be produced, for example, by condensation of nitrosobenzene with 5-amino-isophthalic acid and treatment of the dicarboxylic acid thus obtained with thionyl chloride, and that after recrystallization from gasoline. :

  shows the melting point 121 ° C., are condensed in o-dichlorobenzene by heating for several times with 70 parts of 1-amino-Zi-benzoylamiuoanthraquinone. The dye formed is then filtered off with suction, washed and dried.
