Description

  

  Verfahren zur Herstellung eines     Azofarbstoifes.       Gegenstand des vorliegenden     Zusatz-          .)atentes    ist ein Verfahren zur Herstellung       :ines        Azofarbstoffes,    welches dadurch     ge-          ;ennzeichnet    ist, dass man die     Diazoverbin-          '.ung    von     2-Amino-4'-isooctyldiphenyläther          iit        1-(4-Chlor-3,6-dimethyl-l-sulfamino)-8-          Yynaphthalin-3,6-disulfonsäure    kuppelt.  



  <I>Beispiel:</I>  521,5 Gewichtsteile 1-(4-Chlor-3,6-di       aethyl-1-sulfamino)-8-oxynaphthalin-3,6-di-          ulfonsäure    werden als     Dinatriumsalz    in       Vasser    gelöst. Nach Zugabe von     überschüs-          igem        Natriumacetat    lässt man .eine aus  97 Gewichtsteilen     2-Amino-4'-isooctyldi-          henyläther    erhaltene     Diazolösung    zulaufen.       )ie    Kupplung ist schnell beendet. Der     Farb-          toff    wird abgesaugt und getrocknet.

      Er stellt ein wasserlösliches, rotes Pulver  dar, das Wolle in roten Tönen von sehr guter  Wasch- und     Walkeehtheit    färbt.



  Process for the production of an azo dye. The subject of the present additional.) Atentes is a process for the production of: an azo dye, which is characterized in that the diazo connection of 2-amino-4'-isooctyldiphenyl ether with 1- (4-chloro- 3,6-dimethyl-1-sulfamino) -8-yynaphthalene-3,6-disulfonic acid couples.



  <I> Example: </I> 521.5 parts by weight of 1- (4-chloro-3,6-di-ethyl-1-sulfamino) -8-oxynaphthalene-3,6-di-sulfonic acid are dissolved as the disodium salt in water. After excess sodium acetate has been added, a diazo solution obtained from 97 parts by weight of 2-amino-4'-isooctyldihenyl ether is allowed to run in. ) The clutch is finished quickly. The dye is suctioned off and dried.

      It is a water-soluble, red powder that dyes wool in red shades that are very easy to wash and loosen.
