  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 213909.    Verfahren zur Herstellung eines     Schwefelfarbstoffes.       Nach dem im Hauptpatent beschriebenen  Verfahren erhält man einen Baumwolle in  sehr guten, echten     'Tönen    färbenden Farb  stoff, wenn man     Coronen    mit     sehwefelnden     Mitteln behandelt.  



  Wie nun     weiter    gefunden wurde, erhält  man einen Farbstoff von ähnlichen Echtheits  eigenschaften, wenn man die ,aus 6     Mol          Chlorsulfonsäure    und 1     Mol        Coronen    erhält  liche     Sulfonsäure    mit schwefelnden     Mitteln     behandelt.  



       Beispiel:     Die durch Einwirkung von 6     Mol        Chlor-          sulfonsäure    auf 1     Mol        Coronen        erhaltene          >ulfosäure    wird mit Natronlauge neutra  lisiert und unter Zugabe von 1590 Teilen       Schwefel    und 3180 Teilen     Natriumsulfid          krist.    eingedampft und langsam auf 310 bis  <B>320'</B> erhitzt.

   Die Aufarbeitung der Farb-         stoffrohschmelze    geschieht in üblicher     Weise     durch Aufschliessen mit     Natriumsulfid    und  Ausfällen des Farbstoffes aus der Lösung  mit Säure. Man erhält<B>1110</B> Teile starken  Farbstoff, der Baumwolle in     rötliehen    Khaki  tönen färbt.



  <B> Additional patent </B> to main patent no. 213909. Process for the production of a sulfur dye. According to the process described in the main patent, you get a cotton in very good, real 'tones coloring dye, if you treat coronene with sulfurizing agents.



  As has now been found further, a dye with similar fastness properties is obtained if the sulfonic acid obtained from 6 moles of chlorosulfonic acid and 1 mole of coronene is treated with sulfurizing agents.



       Example: The sulfonic acid obtained by the action of 6 moles of chlorosulfonic acid on 1 mole of coronene is neutralized with sodium hydroxide solution and crystallized with the addition of 1590 parts of sulfur and 3180 parts of sodium sulfide. evaporated and slowly heated to 310 to <B> 320 '</B>.

   The raw dyestuff melt is worked up in the customary manner by digestion with sodium sulfide and precipitation of the dyestuff from the solution with acid. This gives <B> 1110 </B> parts of strong dye which dyes cotton in reddish khaki tones.
