Description

  

  Verfahren zur Herstellung eines sauren     1Vlonoazofar        bstoffes.       Es wurde gefunden, dass man einen sau  ren     Monoazofarbstof    f.' herstellen kann, wenn       ivan    die     Diazoverbindung    des     2-Amino-4-          äulfo-4'-chlor-1,1'-diphenylsulfons    mit Äthyl  ss-naphtylamin kuppelt.

   Der neue Farbstoff       hildet    ein     braunrotes    Pulver,     das    sich in       Nasser    mit blauroter, in konzentrierter       Schwefelsäure    mit brauner Farbe löst und       \Volle    aus essigsaurem Bade in sehr     gleich-          niiissigen,    lebhaften, vollen, licht- und wasch  echten, blauroten Tönen färbt.  



  <I>Beispiel:</I>  88,4 Teile der     Dia.zoverbindung    des       ?-        Ainino--l-sulfo-4'-clilor-1,1'-diphexiylstclfons          (erhalten    zum Beispiel durch Kondensieren  der     p-Clilorbenzolsulfinsäure    mit     1-Chlor-2-          iiiti-ijl)en7ol-4-sulfos < iure,    Reduzieren und     DI-          azotieren    des     Kondensationsproduktes)        wer-          den    in 500 Teilen Wasser verteilt und mit       einer    Lösung von 20,

  7 Teilen Xthyl-ss-naph-         tylamin-ehlorhydrat    versetzt. Die Kupplung  tritt sehr bald ein; sie wird durch vorsich  tiges Abstumpfen der freien Mineralsäure ge  fördert. Der gebildete Farbstoff wird alka  lisch     ausgesalzen    und     abfiltriert.  



  Process for the production of an acidic 1-vlonoazo dye. It has been found that an acidic monoazo dye can be used. can produce if ivan couples the diazo compound of 2-amino-4-sulfo-4'-chloro-1,1'-diphenylsulfone with ethyl ss-naphthylamine.

   The new dye forms a brownish-red powder which dissolves in water with blue-red color, in concentrated sulfuric acid with brown color, and turns full from acetic acid bath in very indifferent, lively, full, light and washable, blue-red tones.



  <I> Example: </I> 88.4 parts of the dia.zo compound of? - ainino - l-sulfo-4'-clilor-1,1'-diphexylstclfons (obtained for example by condensing p-clilobenzenesulfinic acid with 1 -Chlor-2- iiiti-ijl) en7ol-4-sulfos <iure, reducing and diazotizing the condensation product) are distributed in 500 parts of water and mixed with a solution of 20,

  7 parts of ethyl-ss-naphthylamine-chlorohydrate are added. The clutch occurs very soon; it is promoted by carefully blunting the free mineral acid. The dye formed is salted out alkali and filtered off.
