Description

  

  Verfahren zur Herstellung eines sauren     Nonoazofarbstoffes.       Es wurde gefunden,     dass    man einen sauren       .#l,onoitzofarbstoff    herstellen kann, wenn man  die     Diazoverbindung    des in     5"-Stellung        ace-          tylierten        2,5"-Diamino-4-sulio-4"-metliyl-1,1'-          diphenylsulfons    mit     Äthylbenzylaii.ilin    kup  pelt.

   Der neue Farbstoff bildet ein     braun-          oranges    Pulver, das sich- in Wasser mit       oranger,    in konzentrierter Schwefelsäure mit       ge     <B>,</B>     Iber    Farbe löst und Wolle aus schwefel  saurem Bade in sehr gleichmässigen, lebhaf  ten, vollen, licht- und waschechten, orangen  Tönen färbt.

      <I>Beispiel:</I>    <B>-11,3</B> Teile der     Diazoverbindung    des in     5'-          Stellung        aoetylierten        2,5-Diamino-4-sulfo-          4'-mü-thyl-1,1"-diphenylsulfons    (erhalten zum  Beispiel durch Kondensieren der     p-Toluol-          sulfinsäure    mit     1-Chlor-2-nitrobenzol-4-sulfo-          säure,    Nitrieren, Reduzieren,     Acetylieren     und     Diazotieren    des Kondensationsproduk  tes) werden in<B>500</B> teilen Wasser verteilt  und mit einer Lösung von 21,

  1 Teilen Äthyl-         benzylanilin    in<B>11</B> Teilen Salzsäure versetzt.  Die Kupplung tritt sehr bald ein, sie wird  durch vorsichtiges Abstumpfen der freien  Mineralsäure- gefördert. Der gebildete Farb  stoff wird alkalisch     ausgesalzen    und     abfil-          triert.  



  Process for the preparation of an acidic nonoazo dye. It has been found that an acidic. # L, onoitzo dye can be produced if the diazo compound of the 2,5 "-diamino-4-sulio-4" -metliyl-1,1'- acetylated in the 5 "position diphenylsulfons with Äthylbenzylaii.ilin kup pelt.

   The new dye forms a brown-orange powder that dissolves in water with orange, in concentrated sulfuric acid with a <B>, </B> Iber color and wool from a sulfuric acid bath in a very even, lively, full, light - and colors in real orange tones.

      <I> Example: </I> <B> -11.3 </B> parts of the diazo compound of 2,5-diamino-4-sulfo-4'-methyl-1,1 aoetylated in the 5'-position "Diphenyl sulfone (obtained for example by condensing p-toluenesulfinic acid with 1-chloro-2-nitrobenzene-4-sulfonic acid, nitrating, reducing, acetylating and diazotizing the condensation product) are in <B> 500 </ B > share water distributed and 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 under alkaline conditions and filtered off.

PATENTANSPRUCH: Verfahren zur Herstellung eines sauren Monoazofarbstoffes, dadurch gekennzeichnet, dass man die Diazoverbindung des in ä'- Stellung acetylierten 2,5"-Diamino-4-sulfo- 4'-methyl-1,1-diphenylsulfons mit Äthyl- benzylanilin kuppelt. PATENT CLAIM: A process for the preparation of an acidic monoazo dye, characterized in that the diazo compound of the 2,5 "-diamino-4-sulfo-4'-methyl-1,1-diphenylsulfone acetylated in the ä'-position is coupled with ethylbenzylaniline. Der neue Farbstoff bildet ein braunoranges Pulver, das sieh in Wasser mit oranger, in konzentrierter Schwe felsäure mit gelber Farbe löst und Wolle aus schwefelsaurem Bade in sehr gleichmässigen, lebhaften, vollen, licht- und waschechten, orangen Tönen färbt. 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 sulfuric acid bath in very even, lively, full, light and washfast, orange tones.
