Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden,     dass        nian    einen neuen       Azofarbstoff        ei-hält,    wenn man     diazotiertes     Anilin mit     Diacetyl-1   <B>.</B>     4-diamino-8-oxynaph-          thalin-6-sulfonsätire    vereinigt. Der neue Farb  stoff bildet ein dunkles Pulver, löst sich in       Wasger    mit blauroter Farbe und färbt Wolle  aus saurem Bade in lebhaften roten Tönen.

    <I>Beispiel:</I>  34 Teile der     Diacetyl-1   <B>.</B>     4-diamiiio-8-oxy-          tiaphth,itliti-6-sulfosäure    werden als     Natrium-          salz    neutral gelöst und mit einer aus     äqui-          valeriten    Teilen Anilin in üblicher Weise  hergestellten     Diazolbsung        ammoniakalisch    oder       sodaalkalisch    gekuppelt. Die Kupplung geht    sehr rasch und der ausgefallene Farbstoff       abgenutscht    und getrocknet.



  Process for the production of a new azo dye. It has been found that a new azo dye is retained when diazotized aniline is combined with diacetyl-1. 4-diamino-8-oxynaphthalene-6-sulfonic acid. The new dye forms a dark powder, dissolves in wasger with a blue-red color and dyes wool from an acid bath in vivid red tones.

    <I> Example: </I> 34 parts of the diacetyl-1 <B>. </B> 4-diamiiio-8-oxy-tiaphth, itliti-6-sulfonic acid are dissolved neutrally as a sodium salt and treated with an equi - Valerite parts of aniline in the usual way produced Diazolbsung ammoniacally or soda-alkaline coupled. The coupling goes very quickly and the precipitated dye is suction filtered and dried.
