  Zusatzpatent zum     l-fauptpatent    Nr. 226453.    Verfahren zur     Vierstellung    eines Schwefelfarbstoffes.         Vorliegendes    Patent bezieht sieh auf ein  Verfahren zur Herstellung eines Schwefel  fambstoffes.,dadurch gekennzeichnet,     dass    man       14,15-Benzco,eramidonin    (siehe deutsche Pa  tentschrift Nr. 272614) mit einem     Schwefel-          Chh,lorschwefelgemisch    behandelt.  



  Dem so erhaltene Farbstoff ist     .ein        schwärz-          liches    Pulver     und    färbt die pflanzliche Faser  aus dem     @Schwpfelnatriumbad    in     oliwtichig     braunen Tönen von .guter Echtheit,     insbeson-          dere    von guter Lichtechtheit.

      <I>Beispiel:</I>         Zueiner    Schmelze von 12 Teilen Schwefel  in 150 Teilen     Chlorschwefel    werden allmäh  lich 40 Teile     14,15-Benzcoeramidonin    bei 70  bis 80      eingetragen.    Man heizt langsam auf  150 , kocht 1     Stunde        unter        Rückfluss    und       destilliert    dann bis zur Trockne.

   Dann wird    die     T",eratur    bis auf 270  erhöht und 6  Stunden bei dieser     Temperatur        gehalten.          Durch:        Nachbehandlung    mit     Schwefelnatrium     und     Natronlauge        wird    der Farbstoff in  üblicher Weise aufgeschlossen und auf  gearbeitet.



  Additional patent to the main patent No. 226453. Process for the four-position of a sulfur dye. The present patent relates to a process for the production of a sulfur fiber., Characterized in that 14,15-Benzco, eramidonin (see German Patent No. 272614) is treated with a sulfur, chlorosulfur mixture.



  The dyestuff obtained in this way is a blackish powder and dyes the vegetable fibers from the sulfur sodium bath in olive-brown shades of good fastness, in particular good light fastness.

      <I> Example: </I> To a melt of 12 parts of sulfur in 150 parts of chlorosulfur, 40 parts of 14,15-benzcoeramidonine are gradually added at 70 to 80. The mixture is slowly heated to 150, refluxed for 1 hour and then distilled to dryness.

   The temperature is then increased to 270 and kept at this temperature for 6 hours. The dye is broken down and worked up in the usual way by post-treatment with sodium sulphide and sodium hydroxide solution.
