  Zusatzpatent zum     Hauptpatent    Nr. 230266.    Verfahren zur Herstellung eines Schwefelfarbstoffes.    Im     Hauptpatent    ist ein Verfahren     zur     Herstellung eines     @Schwef        elfarbetoffes    be  schrieben, gemäss welchem man =das durch  Kondensieren von     Tetrachlorpyrenchinon,     wie es erhältlich ist durch Behandeln von  1.2.8.5.6.7 .8.10 -     Octochlor-1.2.6.7--tetrahy        dro-          pyren    mit     Oleum,    mit     Anilin    ,im     Molverhält-          nis    1 :

   1 erhaltene Kondensationsprodukt der       Versehwefelung    unterwirft.  



       Wie    nun weiter gefunden wurde, erhält  man einen Farbstoff mit sehr ähnlichen  Eigenschaften,     wenn    man das ,durch Konden  sation des:     Isomerengemisches    der     Tetrachlor-          pyrencUinone,    wie es durch Behandeln von       1.2.3.5.6.7.8.10-Octoch@lor-1.2.6.7-tetrahydro-          pyren    mit     Oleum    erhältlich ist, mit     1-Amino-          4-oxybenzol    im     Molverhältnis,    1:

  1 erhal  tene Kondensationsprodukt der     Versehwefe-          lung        unterwirft.     



  <I>Beispiel:</I>  10     Gewichtsteile    des Kondensationspro  duktes aus     Tetrachlorpyrenchinon        (Isomeren-          gemisch),    wie es durch Behandlung von       1.2.3.5.6.7.8,10    -     Octochlor-1.2.6.7-tetrahydro-          pyren    mit     Oleum    .erhältlich ist; mit 1-Amino-         4-oxybenzol    im     Molverhältnis    1 :

   1 werden  mit     etwa   <B>40</B>     Gewichtsteilen    Schwefel bis zur       Beendigung    der     Fürbstoffbildung    auf 240       biss    280  erhitzt. Man. erhält nach dem übli  chen Aufschliessen mit     Schwefelnatrium          einen    Farbstoff, .der Baumwolle in sehr  schönen vollen, dunkelbraunen     Tönen,    färbt.  Die Färbungen zeigen sehr gute     Echtheits-          eigenschaften.  



  Additional patent to main patent no. 230266. Process for the production of a sulfur dye. In the main patent, a process for the production of a sulfuric dye is described, according to which one = that by condensing tetrachloropyrenequinone, as can be obtained by treating 1.2.8.5.6.7.8.10 - octochloro-1.2.6.7 - tetrahydropyren with oleum, with aniline, in a molar ratio of 1:

   1 condensation product obtained is subjected to sulfurization.



       As has now been found further, one obtains a dye with very similar properties, if one, by condensation of the: isomer mixture of the tetrachloropyrenecUinones, as it is by treating 1.2.3.5.6.7.8.10-Octoch@lor-1.2.6.7 tetrahydropyrene is available with oleum, with 1-amino-4-oxybenzene in a molar ratio of 1:

  1 condensation product obtained is subjected to the sulfurization.



  <I> Example: </I> 10 parts by weight of the condensation product made from tetrachloropyrenequinone (mixture of isomers), as obtainable by treating 1.2.3.5.6.7.8,10-octochloro-1.2.6.7-tetrahydropyrene with oleum is; with 1-amino-4-oxybenzene in a molar ratio of 1:

   1 are heated to 240 to 280 with about 40 parts by weight of sulfur until the formation of the substance is complete. Man. After the usual disintegration with sodium sulphide, it receives a dye that dyes cotton in very beautiful, full, dark brown tones. The dyeings show very good fastness properties.
