Description

  

  Verfahren zur Herstellung eines     Sehwefelfarbstoifes.       Im Hauptpatent ist     lein    Verfahren zur  Herstellung eines Schwefelfarbstoffes be  schrieben, gemäss welchem man das durch  Kondensieren von     Tetrachlorpyrenchinon,     wie es erhältlich ist durch Behandeln von       l..2.3,.5.6.7.8.10-Oetochlor-1.2.6.7-tetrahyd@ro-          pyren    mit     Oleum,    mit Anilin im Molverhält-         nie    1 : 1 erhaltene Kondensationsprodukt der       Vers-chwefelung    unterwirft.  



  Wie nun weiter gefunden wurde,     erhält     man     einen:    Farbstoff mit sehr ähnlichen  Eigenschaften, wenn man das durch Konden  sieren von     Perchlorhydropyrenchinon,    wie es  erhältlich ist durch Behandlung von     Per-          chlorhydropyren    :der Formel  
EMI0001.0014     
         mit        Oleum,    mit Anilin im     Molverhältnis    1 : 1  erhaltene Kondensationsprodukt der     Ver-          schwefelung    unterwirft.

           Beispiel:     10     Gewichtsteile    des     Kondensations-          produktes    aus     Perchlorhydropyrenchinon,    er-           hältlich    aus     Perchlorhydropyren    von der  Formel  
EMI0002.0003     
    (Annalen der Chemie, Band 581, S. 91) durch  Behandeln mit     Oleum,        mit    Anilin im     Mol-          verhältnis    1     :

  1    werden     unter    Zugabe von  etwa 40     Gewichtsteilen    Schwefel bei 240 bis       280         verbacken,        bis    die     Farbstoffbildung        zit     Ende gegangen ist. Man erhält einen Farb  stoff, der Baumwolle in feldgrauen Tönen  mit vorzüglichen     Echtheitseigenschaften     färbt.



  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 tetrachloropyrenequinone, as can be obtained by treating 1.2.3, .5.6.7.8.10-Oetochlor-1.2.6.7-tetrahyd @ ro- Pyrene with oleum, with aniline in a molar ratio of 1: 1, is subjected to the sulphurisation of the condensation product.



  As has now been further found, one obtains a: Dye with very similar properties, if this is obtained by condensing perchlorhydropyrenequinone, as it is obtainable by treating perchlorohydropyrene: of the formula
EMI0001.0014
         with oleum, with aniline in a molar ratio of 1: 1, is subjected to sulphurisation.

           Example: 10 parts by weight of the condensation product of perchlorhydropyrenequinone, obtainable from perchlorhydropyrene of the formula
EMI0002.0003
    (Annalen der Chemie, Volume 581, p. 91) by treatment with oleum, with aniline in the molar ratio 1:

  1 are baked with the addition of about 40 parts by weight of sulfur at 240 to 280 until the dye formation is at the end. A dye is obtained which dyes cotton in field gray tones with excellent fastness properties.

PATENTANSPRUCH: Verfahren zur Herstellung eines Schwe felfarbstoffes, dadurch gekennzeichnet, dass nian das durch Kondensieren von Perchlor- hydropyrenchinon, wie es erhältlieh ist durch Behandeln von Perchlorbydropyren der Formel EMI0002.0023 mit Oleum, mit Anilin im Molverhältnis 1 : 1 erhaltene Kondensationsprodukt der Ver- sehwefelung unterwirft. Der Farbstoff färbt Baumwolle in feld grauen Tönen mit vorzüglicher Echtheit. PATENT CLAIM: A process for the production of a sulfur dye, characterized in that it is obtained by condensing perchlorohydropyrenequinone, as it is obtained by treating perchlorobydropyrene of the formula EMI0002.0023 with oleum, with aniline in a molar ratio of 1: 1, subjected to sulphurisation. The dye dyes cotton in field gray tones with excellent fastness.
