Description

  

  verfahren zur Herstellung eines sauren     1Vlonoazofarbstoffes.       Es wurde befunden, dass man     einen    sauren       Monoazofarbstoff    herstellen kann, wenn man  die     Diazoverbinclung    des     2-Amino-4-sulfo-4'-          niethyl-1,1'-diphenylsulfons    mit     Äthylben-          zylanilin    kuppelt.

   Der neue Farbstoff bildet  ein     braunoranges    Pulver, das sich in Wasser  mit oranger,     in    konzentrierter Schwefelsäure  mit gelber Farbe löst und Wolle aus essig  saurem Bade in     sehr    gleichmässigen, lebhaf  ten, vollen, licht- und waschechten,     orangen     Tönen färbt.  



  <I>Beispiel:</I>  35,6 Teile der     Diazoverbindung    des 2  Amino-4-sulfo-4'-methyl-1,1'-diphenylsulfons  (erhalten zum Beispiel durch Kondensieren  der     p-Toluolsulfinsäure    mit     1-Chlor-2-nitro-          benzol-4-sulfosäure,    Reduzieren und     Diazo-          tieren    des     Kondensationsproduktes)    werden in  500 Teilen Wasser verteilt und mit einer  Lösung von 21,1 Teilen     Äthylbenzylanilin       in 11 Teilen Salzsäure versetzt. Die Kupp  lung tritt sehr bald ein; sie wird durch vor  sichtiges Abstumpfen der freien     Mineralsäure     gefördert.

   Der     gebildete    Farbstoff wird al  kalisch     ausgesalzen    und     abfiltriert.  



  Process for the production of an acidic 1Vlonoazo dye. It has been found that an acidic monoazo dye can be produced by coupling the diazo compound of 2-amino-4-sulfo-4'-niethyl-1,1'-diphenylsulfone with ethylbenzylaniline.

   The new dye forms a brown-orange powder that dissolves in water with orange, in concentrated sulfuric acid with yellow color and colors wool from an acidic bath in very even, lively, full, lightfast and washfast, orange tones.



  <I> Example: </I> 35.6 parts of the diazo compound of 2-amino-4-sulfo-4'-methyl-1,1'-diphenylsulfone (obtained for example by condensing p-toluenesulfinic acid with 1-chloro-2 -nitrobenzene-4-sulfonic acid, reducing and diazotizing the condensation product) are distributed in 500 parts of water and mixed with a solution of 21.1 parts of ethylbenzylaniline in 11 parts of hydrochloric acid. The coupling occurs very soon; it is promoted by careful blunting of the free mineral acid.

   The dye formed is salted out and filtered off.
