Description

  

  Zusatzpatent zum Hauptpatent     Nr.   <B>90093.</B>    Verfahren zur Herstellung eines sauren     Monoazofarbstoffes.       Es wurde gefunden,     dass    man einen sau  ren     Monoazofarbstoff    herstellen kann, wenn  man die     Diazoverbindung    des in     4-Stellung          acetylierten        2,4-Diainirio-4'-inethyl-5'-sulfo-          1"1'-diphenylstilfotis    mit     Äthylbenzylanilin     kuppelt.

   Der neue Farbstoff bildet ein     braun-          oranges    Pulver, das sich in Wasser mit       oranger,    in konzentrierter Schwefelsäure mit  gelber Farbe löst     und    Wolle ans     schwefel-          saurein    Bade in sehr gleichmässigen, lebhaften,  vollen, licht- und waschechten, orangen Tönen  färbt.  



  <I>Beispiel:</I>  41,3 Teile der     Diazoverbindung    des in       4-Stellung        acetylierten        2,4-Diamino-4'-inethyl-          5'-sulfo-1,1'-diphenylsulfoiis    (erhalten zum  Beispiel durch Kondensieren von     p-Toltiol-          sulfinsäure    mit     2,4-Diiiitro-l-chlot-beiizol,        Sul-          fleren,    Reduzieren,     Acetylieren    und     Diazo-          tieren    des Kondensationsproduktes) werden  in<B>500</B> Teilen Wasser verteilt und mit einer  Lösung von 21,

  1 Teilen     Äthylbenzylanilin       in<B>11</B> Teilen Salzsäure versetzt. Die Kupp  lung tritt sehr bald ein; sie wird durch vor  sichtiges Abstumpfen der freien Mineralsäure  gefördert. Der gebildete Farbstoff wird alka  lisch     ausgesalzen    und     abfiltriert.  



  Additional patent to main patent no. <B> 90093. </B> Process for producing an acidic monoazo dye. It has been found that an acidic monoazo dye can be produced if the diazo compound of 2,4-diainirio-4'-ynethyl-5'-sulfo-1 "1'-diphenylstilfotis is coupled 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 in the sulfuric acid bath in very even, lively, full, lightfast and washfast, orange tones.



  <I> Example: </I> 41.3 parts of the diazo compound of 2,4-diamino-4'-ynethyl-5'-sulfo-1,1'-diphenylsulfoiis acetylated in the 4-position (obtained for example by condensing p-Toltiolsulfinic acid with 2,4-Diiiitro-1-Chlot-beiizol, Sulfleren, reducing, acetylating and diazotizing the condensation product) are distributed in <B> 500 </B> parts of water and mixed with a solution of 21,

  1 part of ethylbenzylaniline is added to 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 alkali and filtered off.
