  Verfahren zur Darstellung eines     violettstichig    blauen     Schwefelfarbstoffes.       Das vorliegende Verfahren betrifft die  Darstellung eines     violettstichig    blauen Schwe  felfarbstoffes. Es besteht darin,     dass    man     p-          Amido-m-niethyl-p'-oxydiphenylamin    mit einer       Polysulfidlösung    unter Zusatz von     1-nitro-4-          chlorbenzol-3-stilfosaut-em    Natrium erhitzt.

      er  hitzt, der Methylalkohol     abdestilliert    und der  gebildete Farbstoff in üblicher Weise durch  Einblasen eines Luftstromes isoliert.  



  Er stellt ein     violettblaues,    kupferglänzen  des Pulver dar, das in Wasser kaum, in    Alkohol wenig mit     blativioletter    Farbe löslich  ist. In konzentrierter Schwefelsäure löst er  sich mit blauer, in kaltem Anilin und     kai-          tem        Pyridin    mit blauvioletter Farbe. Aus       schwefelnatriumhaltigem    Bade wird Baum  wolle in     violettbraunen    Tönen angefärbt,  die beim     Verhänoen    rasch in ein     violett-          stichiges    Blau übergehen. Der so erhaltene  Farbstoff färbt klarere und blauere Töne als  der bei Gegenwart von z.

  Process for the preparation of a purple-tinged blue sulfur dye. The present method relates to the preparation of a violet-tinged blue sulfur dye. It consists in heating p-amido-m-niethyl-p'-oxydiphenylamine with a polysulfide solution with the addition of sodium 1-nitro-4-chlorobenzene-3-stilfosaut-em.



  <I> Example: </I> <B> 26.3 </B> parts by weight of p-araido-m-methyl-p -'-oxydiphenylamine and <B> 88 </B> parts by weight of 1- iiiti-o-4 Sodium chlorobenzene-S-sulphonic acid is concentrated in a polysulphide solution of <B> 750 </B> parts by volume of methyl alcohol, <B> 32 </B> parts by weight of sodium sulphide 60 <B> '</B> J62%, 24 Parts by weight of sulfur entered and the mixture in the leaded autoclave <B> 10 </B> hours for <B> 125-130 </B> ()

      it heats, the methyl alcohol is distilled off and the dye formed is isolated in the usual manner by blowing in a stream of air.



  It represents a violet-blue, copper-shimmering powder, which is hardly soluble in water and hardly soluble in alcohol with a blativiolet color. It dissolves in concentrated sulfuric acid with blue, in cold aniline and cold pyridine with a blue-violet color. From baths containing sodium sulphide, cotton is dyed in violet-brown tones, which quickly turn into a violet-tinged blue when worn. The dye obtained in this way colors clearer and bluer shades than that in the presence of e.g.

   B. nitrauilin by the method of patent <B> 78901 </B> he obtained dye.
