  <B>Zusatzpatent</B> zum     Hauptpatent    Nr. 230266.    Verfahren zur Herstellung eines Schwefelfarbstoffes.    Im Hauptpatent ist ein Verfahren zur  Herstellung eines Schwefelfarbstoffes be  schrieben, gemäss welchem man das durch  Kondensieren von     Tetrachlorpyrenchino:n,     wie es erhältlich ist durch Behandeln von  1:2.3.5.6.7 .8.10 -     Octo        chlor--1.2.6.7-        tetrahydro-          pyren    mit     Oleum,    mit Anilin im     Molverhält-          nis    1 : 1 erhaltene     Kondensationsprodukt    der       Verschwefelung    unterwirft.  



  Wie nun weiter gefunden wurde, erhält  man     einen.    Farbstoff mit sehr ähnlichen Ei  genschaften, wenn, man das durch Kondensa  tion des     Isomerengemisches    .der     Tetrachlor-          pyrenchinone,    wie es durch Behandeln von       1.2.3.5.6.7.8\.10    -     Octochlor-.1.2.6.7-        tetrahydro-          pyren    mit     Oleum    erhältlich ist, mit     Butyl-          amin    im     Molverhältnis    1 :

   1 erhaltene Kon  densationsprodukt der     Versühwefelung        un-          terwirft.     



  <I>Beispiel:</I>  10 Gewichtsteile des     Kondensationspro-          duktes    aus     Tetrachlorpyrenchinon        (Isomeren-          gemisch),    erhältlich durch Behandeln von  7..2.3.5.6.7.8'.10-Oetochlor-1.2.6.7-tetrahvdro-         pyren    mit     Oleum,    und     Butylamin    im     Mol-          verhältnis    1 :

   1 werden mit     etwa    40     Gewichts-          teilenSchwefel    bis zur     Beendigung    der     Farb=          stoffbildung    auf 240-280  erhitzt. Man er  hält nach     dem    üblichen Aufschliessen mit       Schwefelnatrium    einen Farbstoff, der Baum  wolle in sehr .schönen braunen Tönen färbt.  Die Färbungen zeigen ;sehr gute Echtheits  eigenschaften.



  <B> Additional patent </B> to main patent no. 230266. Process for the production of a sulfur dye. In the main patent, a process for the production of a sulfur dye is described, according to which one can obtain this by condensing tetrachloropyrenchino: n, as can be obtained by treating 1: 2.3.5.6.7 .8.10 - octochlor - 1.2.6.7- tetrahydro- Pyrene with oleum, with aniline in a molar ratio of 1: 1, is subjected to sulphurisation.



  As has now been further found, you get one. Dyestuff with very similar properties, if that is done by condensation of the isomer mixture of the tetrachloropyrenequinones, as is the case by treating 1.2.3.5.6.7.8 \ .10-octochloro-.1.2.6.7-tetrahydropyrene with oleum is available with butylamine in a molar ratio of 1:

   1 condensation product obtained is subjected to sulfurization.



  <I> Example: </I> 10 parts by weight of the condensation product of tetrachloropyrenequinone (mixture of isomers), obtainable by treating 7..2.3.5.6.7.8'.10-oetochloro-1.2.6.7-tetrahydropyrene with oleum , and butylamine in the molar ratio 1:

   1 are heated to 240-280 with about 40 parts by weight of sulfur until the dye has formed. After the usual digestion with sodium sulphide, a dye is obtained that dyes the cotton in very beautiful brown tones. The dyeings show very good fastness properties.
