Description
Zusatzpatent zum Hauptpatent Nr. 231257. Verfuhren zur Herstellung eines Baumwolle in braunen Tönen sehr echt färbenden Schwefelfarbstoffes. Gemäss dem im beschriebe- nen Verfahren erhält man einen Baumwolle in sehr echten grauen Tönen färbenden Sehwefel'f.arbsto,ff, wenn man dass durch g:
on- densation des Gemisches der issomeren Di- chlo@rpyrenchinone, wie es erhältlich ist durch Behandlung von 3.5.8.10-Tetrachlorpyren .mit Oleum, und Anilin im Molverhältnis 1 : 1 erhaltene Produkt der Verschwefelung unter- Wirft.
Wie nun weiter gefunden wurde, erhält man einen Baumwolle in sehr echten braunen Tönen färbenden Farbstoff, wenn man das durch Kondensation d @es genannten Gemisches der isomerenDichlorpyrenchinone mitAmin.o- pyren vom Schmelzpunkt F = 116 erhaltene Produkt der Verschwefelung unterwirft.
Beispiel: 10 Gewichtsteile des Kond@ens-ationspro- duktes aus Dichlorpyrenchinon (Isomeren- gem;isch), erhältlich durch Behandeln von 3.5.8.10-Tetrachlorpyren mit Oleum, und Aminopyren vom Schmelzpunkt F<B>=</B> 116 werden mit 40 Gewich7Aeilen :Schwefel auf 240-280 erhitzt, bis die Farbstoffbildung beendet ist.
Man erhält nach der üblichen Aufarbeitung ein schwarzes Farbstoffpulver, ,das Baumwolle in braunen Tönen von guten Echtheitseigenschaften färbt.
Additional patent to the main patent no. 231257. Process for the production of a sulfur dye with very fast coloring in brown tones. According to the method described in the above, one obtains a sulfuric acid coloring cotton in very genuine gray tones, if one follows that by g
on- densation of the mixture of isomeric dichlo @ rpyrenquinones, as it is obtainable by treating 3.5.8.10-tetrachloropyrene with oleum, and aniline in a molar ratio of 1: 1, the product obtained is subject to sulphurisation.
As has now been further found, a dye which dyes cotton in very genuine brown shades is obtained if the product obtained by condensation of the mixture of isomeric dichloropyrenquinones with amine.opyrene with a melting point of F = 116 is subjected to sulphurisation.
Example: 10 parts by weight of the condensation product from dichloropyrenquinone (isomeric mixture), obtainable by treating 3.5.8.10-tetrachloropyrene with oleum, and aminopyrene with a melting point of F 116 are added 40 parts by weight: sulfur heated to 240-280 until dye formation is complete.
After the usual work-up, a black dye powder is obtained which dyes cotton in brown shades of good fastness properties.
