  Verfahren zur Herstellung eines sauren     Wollfarbstoffes.       Im Hauptpatent Nr. 193627 und dem  ersten bis siebzehnten Zusatzpatent sind Ver  fahren zur Herstellung saurer Wollfarbstoffe  beschrieben, bei welchen man     Nitroverbin-          dungen    der allgemeinen Formeln:

    
EMI0001.0004     
    worin Y Halogen oder     eine        Alkogygruppe,     X einen     Alkyl-,        Aryl-    oder     Cycloalkylrest     und Z die Gruppen C0, S02,     CO-aryl-CO     oder     S02-aryl-SO,    bedeuten, mit Aminosul-         fonsäuren    der     Diarylamin-,        Cycloalkyl-aryl-          amin-    oder     Carbazolreihe    kondensiert.  



  Es wurde nun gefunden, dass man zu ana  logen Farbstoffen mit den gleichen wert  vollen Eigenschaften gelangt,     wenn    man für  das genannte Verfahren analoge     Nitroverbin-          dungen    der folgenden allgemeinen Formeln  verwendet:  
EMI0001.0020     
    worin X und Y die oben angegebene Bedeu-           tung    haben und     Z1    die Bedeutung -SO-  oder     -OS-aryl-SO-    hat.  



  Vorliegendes Patent bezieht sich nun auf  ein Verfahren zur Herstellung eines sauren       Wollfarbstoffes,    dadurch gekennzeichnet, dass  man     1-Chlor-2-nitrobenzol-4-methylsulfoxyd     mit     4-Aminodiphenylamin-?-sulfonsäure    kon  densiert.  



  Der so erhaltene Farbstoff färbt Wolle  aus saurem Bade in braunen Tönen von sehr  guter Egalität.  



  <I>Beispiel:</I>  26,4 Teile 4     Aminodiphenylamin-2-sul-          fonsäure,    22 Teile     1-Chlor-\..)-nitrol)enzol-4-          methylsulfoxyd    und 28 Teile kristallisiertes       Natriumacetat    werden mit     etwa   <B>200</B> Teilen  Wasser mehrere     Stunden    unter Rühren und         Rückflusskühlung    zum Sieden erhitzt. Nach  dem Erkalten wird der gebildete Farbstoff  durch Zugabe von wenig Kochsalz ausge  schieden, abgetrennt und getrocknet.



  Process for the production of an acidic wool dye. In the main patent No. 193627 and the first to seventeenth additional patents, processes for the production of acidic wool dyes are described in which nitro compounds of the general formulas are

    
EMI0001.0004
    where Y is halogen or an alkogy group, X is an alkyl, aryl or cycloalkyl radical and Z is the groups C0, S02, CO-aryl-CO or S02-aryl-SO, with aminosulfonic acids of diarylamine, cycloalkyl-aryl amine or carbazole series condensed.



  It has now been found that analog dyes with the same valuable properties are obtained if analogous nitro compounds of the following general formulas are used for the process mentioned:
EMI0001.0020
    in which X and Y have the meaning given above and Z1 has the meaning —SO— or —OS-aryl-SO-.



  The present patent now relates to a process for the production of an acidic wool dye, characterized in that 1-chloro-2-nitrobenzene-4-methylsulfoxide is condensed with 4-aminodiphenylamine -? - sulfonic acid.



  The dye thus obtained dyes wool from an acid bath in brown shades of very good levelness.



  <I> Example: </I> 26.4 parts of 4 aminodiphenylamine-2-sulphonic acid, 22 parts of 1-chloro - \ ..) - nitro) enzene-4-methylsulphoxide and 28 parts of crystallized sodium acetate are mixed with about <B > 200 parts of water heated to boiling for several hours with stirring and reflux cooling. After cooling, the dye formed is separated out by adding a little sodium chloride, separated off and dried.
