  Verfahren zur Darstellung eines neuen     schwefel-    und stickstoffhaltigen     Ifondensations-          produktes    aus dem     Einwirkungsprodukt    von     Chlorschwefel    auf     p-Anisiclin:       Wird das Einwirkungsprodukt von Chlor  schwefel auf     p-Anisidin    von wahrscheinlich  folgender Konstitution:  
EMI0001.0008     
    mit Anilin. kondensiert, so entsteht unter  Austausch der     Oxyalkylgruppe    gegen den       I'henylaminorest    eine neue Verbindung mit  ganz ähnlichen Eigenschaften wie die im  Hauptpatent beschriebene; sie besitzt wahr  scheinlich folgende Zusammensetzung:

    
EMI0001.0011     
    Die neue Verbindung soll zur Herstel  lung von Farbstoffen und pharmazeutischen  Produkten benutzt werden.    <I>Beispiel:</I>  22 kg des fein gemahlenen Einwirkungs  produktes von Chlorschwefel auf     p-Anisidin     (siehe D. R. P. Nr. 360690, Beispiel 6, 2. Ab  satz) werden bei gewöhnlicher Temperatur  in eine Lösung von 10 kg Anilin in etwa  30 kg     Eisessig    eingetragen und mehrere  Stunden gerührt. Die Reaktion verläuft un  ter starker Wärmeentwicklung. Sobald, die  Ausscheidung des Kondensationsproduktes  nicht mehr zunimmt, giesst man das Reak  tionsgemisch in mit Salzsäure angesäuertes  Salzwasser von etwa 15       B6    und filtriert  den kristallinischen Niederschlag ab.

   Zur  Reinigung kristallisiert man ihn aus stark  verdünnter Salzsäure oder Essigsäure um.  



  Man erhält dann metallglänzende Nadeln  oder     Blättchen,    welche sich mit kräftig rot  violetter Farbe in Wasser lösen und auf tan  nierte Baumwolle mit gleicher Farbe auf  ziehen. Alkalien     bezw.    Alkalien und Re  duktionsmittel spalten die neue Verbindung  in     5-Phenylamino-2-amino-l-merkaptobenzol     von der Formel:    
EMI0002.0001     




  Process for the preparation of a new sulfur- and nitrogen-containing ifondensation product from the action product of chlorosulphur on p-anisicline: If the action product of chlorosulphur on p-anisidine will probably have the following constitution:
EMI0001.0008
    with aniline. condensed, a new compound with properties very similar to those described in the main patent is formed by replacing the oxyalkyl group with the phenylamino radical; it probably has the following composition:

    
EMI0001.0011
    The new compound is to be used in the manufacture of dyes and pharmaceutical products. <I> Example: </I> 22 kg of the finely ground action product of chlorosulphur on p-anisidine (see DRP no. 360690, example 6, 2nd paragraph) are at normal temperature in a solution of 10 kg aniline in about Entered 30 kg of glacial acetic acid and stirred for several hours. The reaction takes place under intense heat development. As soon as the excretion of the condensation product no longer increases, the reaction mixture is poured into salt water acidified with hydrochloric acid of about 15 B6 and the crystalline precipitate is filtered off.

   To clean it, it is recrystallized from very dilute hydrochloric acid or acetic acid.



  This gives shiny metal needles or flakes, which dissolve in water with a strong red-violet color and pull on tan-ned cotton with the same color. Alkalis respectively Alkalis and reducing agents split the new compound into 5-phenylamino-2-amino-1-mercaptobenzene of the formula:
EMI0002.0001
