Description

  

  Verfahren zur Herstellung eines     Azofarbstoffes.       Es wurde gefunden, dass man einen     Azo-          farbstoff    erhält, wenn man die     Diazoverbin-          dung    des     1-Amino-4-nitrobenzol-2-methylsul-          fons    mit     (2-Methoxy-5-methyl-2'-sulfonsäure-          4'    -     chloracetylamirio)    - N -     diphenylamin    der  Formel  
EMI0001.0012     
    vereinigt.

   Der neue Farbstoff bildet ein dunk  les Pulver, das sich in Wasser mit violetter  Farbe löst und das Wolle und Seide aus  saurem Bade in     violettblauen    Tönen färbt.  <I>Beispiel:</I>  216 Teile     1-Amino-4-nitrobenzol-2-methyl-          sulfon    werden     diazotiert    und in die mineral  saure Lösung dieser     Diazoverbindung    die Lö  sung des     Natriumsalzes    aus 384 Teilen (2       Methoxy-5-methyl-2'-sulfonsäure-4'-chlorace-          tylamino)-N-diphenylamin    eingetragen.

   Nach  dem die     Farbstoffbildung    beendet ist, wird       abfiltriert,    der Farbstoff in Wasser suspen-         diert    und durch Verrühren mit einem Alkali  neutral gestellt. Der Farbstoff wird eventuell  durch Zusatz eines Salzes ausgeschieden, ab  filtriert und getrocknet.



  Process for the preparation of an azo dye. It has been found that an azo dye is obtained if the diazo compound of 1-amino-4-nitrobenzene-2-methylsulfone is used with (2-methoxy-5-methyl-2'-sulfonic acid-4 '- chloracetylamirio) - N - diphenylamine of the formula
EMI0001.0012
    united.

   The new dye forms a dark powder that dissolves in water with a purple color and dyes the wool and silk from an acid bath in purple-blue tones. <I> Example: </I> 216 parts of 1-amino-4-nitrobenzene-2-methyl sulfone are diazotized and the solution of the sodium salt of 384 parts (2 methoxy-5-methyl- 2'-sulfonic acid-4'-chloroacetylamino) -N-diphenylamine entered.

   After the formation of the dye has ended, it is filtered off, the dye is suspended in water and neutralized by stirring with an alkali. The dye is possibly precipitated by adding a salt, filtered off and dried.
