Description

Verfahren zur Herstellung von gefärbten Produkten der Anthrachinonreihe Nach dem Patent 212 47 i erhält man Küpenfarbstoffe, wenn man Benzanthronyli-aminoanthrachinon oder deren Derivate mit kondensierenden Mitteln behandelt.Process for the manufacture of colored products of the anthraquinone series According to the patent 212 47 i, vat dyes are obtained if benzanthronyli-aminoanthraquinone is used or their derivatives treated with condensing agents.

Es wurde nun gefunden, daß man ganz andere gefärbte Produkte erhält, wenn man die genanntenVerbindungen mit oxydierenden Mitteln behandelt. Die so erhaltenen Produkte geben im allgemeinen eine wenig charakteristisch gefärbte, meist bräunliche Küpe und besitzen eine wechselnde Affinität zur pflanzlichen Faser. Sie können als Küpenfarbstoffe oder als Zwischenprodukte zur Herstellung von Farbstoffen verwendet werden. Beispiel i oTeileBz.-i-Benzanthronyl-i-aminoanthrachinon werden in 15o Teilen Schwefelsäure von 66° Be gelöst. Man kühlt auf o° ab und trägt sodann langsam eine Aufschlämmung von io Teilen künstl. Braunstein in .4o Teilen Schwefelsäure von 66° Be unter dauernder Kühlung auf o° ein. Hierbei schlägt die ursprünglich olivbraune Lösungsfarbe nach Blaugrün um. Wenn die Reaktion beendet ist, was z. B. daran zu erkennen ist, daß eine wesentliche Änderung der Färbung der Lösung nicht mehr eintritt, rührt man in iooo Teilen Wasser ein setzt So Teile Bisulfitlösung von 38 bis 400 Be zu, kocht auf und filtriert. Man erhält einen v iolettblau gefärbten Niederschlag, welcher sich in Schwefelsäure mit blaugrüner Farbe löst und aus rotbrauner Küpe Baumwolle mit der gleichen Farbe anfärbt. Beim Verhängen an der Luft wird die Färbung rotstichigblau. Die Färbung zeichnet sich durch eine vorzügliche Beuchechtheit aus.It has now been found that completely different colored products are obtained, if the compounds mentioned are treated with oxidizing agents. The so obtained Products generally have an uncharacteristically colored, mostly brownish color Küpe and have a changing affinity for vegetable fibers. You can as Vat dyes or used as intermediates in the manufacture of dyes will. Example i oPartsBz.-i-Benzanthronyl-i-aminoanthraquinone are in 150 parts Dissolved sulfuric acid of 66 ° Be. You cool down to 0 ° and then slowly wear one Artificial slurry of 10 parts Brownstone in .40 parts sulfuric acid of 66 ° Be on with constant cooling to o °. Here the originally olive-brown one beats Solution color to blue-green. When the reaction is over, which is e.g. B. to it it can be seen that a significant change in the color of the solution no longer occurs, If the mixture is stirred in 1,000 parts of water, then 38 to 400 parts of bisulfite solution are used Be closed, boil and filter. A purple-blue colored precipitate is obtained, which dissolves in sulfuric acid with a blue-green color and from a red-brown vat Dyes cotton with the same color. When hanging in the air, the coloring reddish blue. The coloring is characterized by an excellent buckling fastness.

Geht man statt von Bz.-i-Benzanthronyli-aminoanthrachinon von dem Kondensationsprodukt aus i, 5-Diaminoanthrachinon mit Mol. Bz.-i-Brombenzanthron aus, so erhält man ein violettes Pulver, das gleichfalls in Schwefelsäure rnit blattgrüner Farbe löslich ist und aus rotbrauner Küpe Baumwolle blaugrau anfärbt.If one goes instead of Bz.-i-Benzanthronyli-aminoanthraquinone from the Condensation product of i, 5-diaminoanthraquinone with Mol. Bz.-i-bromobenzanthrone a violet powder is obtained, which likewise in sulfuric acid turns green with leafy Color is soluble and stains cotton blue-gray from red-brown vat.

Das Kondensationsprodukt aus i-Benzoylamino-5-aininoanthrachinon mit Bz.-i-Brombenzantliron liefert in analoger Weise ein blaugefärbtes Produkt, das sich in Schwefelsäure blaugrün löst und aus blauer Küpe Baumwolle grünstichigblau anfärbt.The condensation product of i-benzoylamino-5-aininoanthraquinone with Bz.-i-bromobenzantlirone provides a blue-colored product in an analogous manner, which dissolves blue-green in sulfuric acid and greenish-tinged blue in cotton from a blue vat stains.
