      Zusatzpatent    zum     Hauptpatent    Nr. 230266.    Verfahren zur Herstellung eines Schwefelfarbstoffes.    Im Hauptpatent ist     ein,    Verfahren zur       Herstellung    eines     Schwefelfarbstoffes    be  schrieben,     gemäss    welchem man     Jass    durch       Kondensieren    des     Isomerengemis,ches;

      der       Tetrachlorpyrenchinone,    wie es erhältlich ist  durch Behandeln von     1.2.3.4.5.6.7.8.10-0-cto-          chlor-1.2.6.7-tetrahydropyren    mit     Oleum,    mit  Anilin im     ATolverhältnis    1 : 1 erhaltene     Kon-          densationsyrodukt    .der     VeTschwefelung    un  terwirft.  



  Es hat sich nun gezeigt,     .dass    man zu  einem Schwefelfarbstoff mit ganz ähnlichen  Eigenschaften     gelangt,    wenn man das durch       Kondensation    des     Ieomerengemisches    der       Tetrachlorpyrenchinone,    wie es erhältlich ist  durch Behandeln von     1.2.3.4.5.6.7.8.10-Octo-          chilor-1.2.6.7-tetrahydropyren    mit     Oleum,    mit  Anilin im     Molverhältnis    1 : 4 erhaltene     Kon-          densationsprocdukt    der     VeTschwefelung    un  terwirft.  



  <I>Beispiel:</I>  10     Gewichtsteile    des aus     Tetrachlorpyren-          chinon        (Isomerengemisch),    wie es erhältlich  ist durch Behandeln von     1.2.3.5.6.7.8.10-Oeto-          chlpr-1.2.6.7-tetrahydropyren    mit     Oleum,    und    Anilin im M     olverhä@ltnis    1 : 4 erhaltenen       Kondensationsproduktes    werden mit     etwa     40     Gewichtsteilen    Schwefel bis zur Beendi  gung der     Farbstoffbildung    .auf 240-280  er  hitzt.

   Man erhält nach dem üblichen Auf  schliessen mit- Schwefelnatrium einen Farb  stoff, der     Baumwolle    in sehr schönem, grün  lich feldgrauem Ton färbt. Die Färbungen  zeigen ,sehr     gute    Echtheitseigenschaften.



      Additional patent to main patent no. 230266. Process for the production of a sulfur dye. In the main patent is a process for the preparation of a sulfur dye be written, according to which one Jass by condensing the isomer mixture, ches;

      the tetrachloropyrenequinones, as obtainable by treating 1.2.3.4.5.6.7.8.10-0-cto-chloro-1.2.6.7-tetrahydropyrene with oleum, condensation product obtained with aniline in a molar ratio of 1: 1, subject to sulfurization .



  It has now been shown that .that one arrives at a sulfur dye with very similar properties, if one that is obtained by condensation of the Ieomeregemisches of the tetrachloropyrenequinones, as it is obtainable by treating 1.2.3.4.5.6.7.8.10-octochloro-1.2 .6.7-tetrahydropyrene with oleum, condensation product obtained with aniline in a molar ratio of 1: 4 subjected to sulphurization.



  <I> Example: </I> 10 parts by weight of the tetrachloropyrene quinone (mixture of isomers), as obtainable by treating 1.2.3.5.6.7.8.10-Oeto- chlpr-1.2.6.7-tetrahydropyrene with oleum, and aniline im The condensation product obtained in a molar ratio of 1: 4 is heated to 240-280 with about 40 parts by weight of sulfur until the dye formation has ended.

   After the usual opening with sodium sulphide, a dye is obtained which dyes cotton in a very beautiful, greenish field gray shade. The dyeings show very good fastness properties.
