Description

  

  Verfahren zur Herstellung eines     Azofarbstoffes.       Es wurde gefunden, dass man einen wert  vollen     Azofarbstoff    dadurch erhält, dass man       diazotiertes    1     -Aminobenzol-4-sulfonsäure-          dioxyäthylamid    mit 1-     Acetylamino-8-ogy-          naphtalin    - 4     #    6 -     disulfonsäure    kuppelt.  



  <I>Beispiel:</I>  26,2 Gewichtsteile 1. -     Aminoberrzol-4-          sulfonsäure-dioxydäthylamid    (hergestellt durch  Kondensieren von     1-Nitrobenzol-4-sulfon-          säurechlorid    mit     Dioxyäthylamin        [NH    =     (CHs          CHE    -     0H)2]    und nachfolgendes Reduzieren)       werden    in üblicher Weise     diazotiert    und mit  52,

  5 Gewichtsteilen des     Natriumsalzes    der  1 -     Acetylamino    - 8 -     oxynaphtalin    -4.6 -     disul-          fonsäure    in     sodaalkalischer    Lösung gekuppelt.    Der     Farbstoff    färbt Wolle in lebhaften blau  roten Tönen und besitzt sehr gutes     Egalisie-          rungsvermögen.  



  Process for the preparation of an azo dye. It has been found that a valuable azo dye is obtained by coupling diazotized 1-aminobenzene-4-sulfonic acid dioxyethyl amide with 1-acetylamino-8-ogy naphthalene - 4 # 6 - disulfonic acid.



  <I> Example: </I> 26.2 parts by weight 1. - Aminoberrzene-4-sulfonic acid-dioxydethylamide (produced by condensing 1-nitrobenzene-4-sulfonic acid chloride with dioxyethylamine [NH = (CHs CHE - 0H) 2] and subsequent reduction) are diazotized in the usual way and with 52,

  5 parts by weight of the sodium salt of 1 - acetylamino - 8 - oxynaphthalene -4.6 - disulphonic acid coupled in a soda-alkaline solution. The dye dyes wool in lively blue-red tones and has very good leveling properties.
