Description

  

  Verfahren zur Herstellung eines sauren     Monoazofarbstoffes:       Es wurde gefunden, dass man einen sau  ren     111onoazofarbstoff    herstellen kann, wenn  man die     Diazoverbindung    des     2-Amino-4-          sulfo-a'-methyl-1.,1'-diphenylsulfons    mit N  Hethy     1-diphenylamin    kuppelt.

   Der neue  Farbstoff bildet ein     braunoranges    Pulver,  das sich in Wasser mit oranger, in konzen  trierter -Schwefelsäure mit violetter Farbe       Mt        und    Wolle aus essigsaurem Bade in sehr       (Pleichmässigen,    lebhaften, vollen, licht- und       waschechten,    orangen Tönen färbt.

           Beispiel:       35.6 Teile der     Diazoverbindung    des     2-          a.mino-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  <B>.IM</B> Teilen Wasser verteilt und mit einer       wässerigen    Suspension von 18,3 Teilen N-         Methyldiphenylamin    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 preparation of an acidic monoazo dye: It has been found that an acidic monoazo dye can be prepared if the diazo compound of 2-amino-4-sulfo-a'-methyl-1., 1'-diphenyl sulfone is mixed with N Hethy 1- diphenylamine couples.

   The new dye forms a brown-orange powder, which is colored in water with orange, in concentrated sulfuric acid with violet color and wool from acetic acid bath in very (regular, lively, full, light and washfast, orange tones.

           Example: 35.6 parts of the diazo compound of 2- a.mino-4-sulfo-4'-methyl-1,1'-diphenyl sulfone (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 <B> .IM </B> parts of water and mixed with an aqueous suspension of 18.3 parts of N-methyldiphenylamine.

   The clutch occurs very soon; It is promoted by careful blunting of the free mineral acid. The dye formed is salted out by alkali and filtered off.
