Description
Verfahren zur Darstellung eines leicht wasserlöslichen Farbstoffes der Anthrachinonreilie. In der Patentschrift Nr.<B>71038</B> und dem Zusatzpatent Nr. 71656 sind Verfahren be schrieben, nach welchen in 1-Arnino-2-halogen- 4-arylaminoanthrachinorren und deren Sulfo- säuren durch Behandeln mit Sulfiten das Halogenatom gegen die Sulfogruppe ausge tauscht wird.
Zurre Beispiel wird 1-Amino- 2-brom-4-p-tolylaminoanthrachinon mit einer Lösung von galiumsulfit in Wasser unter Zusatz von Phenol unter Rückfluss gekocht, bis keine Zunahme der Bildung an wasser löslichen Farbstoffen mehr stattfindet.
Es wurde nun gefunden, dass technisch sehr wertvolle kernsubstituierte Polysulfo- säuren von Arylaminoanthrachinonen (zum Beispiel Di- und Trisulfosäuren) erhalten werden können, wenn die ,ss-Halogenderivate der heteronuclear in a- oder P-Stellung sul- fierten Arylaminoanthrachinone mit Sulfit unter Zusatz von Phenol oder ähnlich wir kenden Substanzen behandelt werden.
Es können auch Produkte zur Verwendung gelangen, welche im Arylaminorest eine Acylaminogruppe oder einen andern Substi- tuenten enthalten. Abgesehen davon, dass derartige Disulfosäuren, welche die Sulfo- gruppen auf beide Benzolkerne im Anthra- chinon verteilt enthalten, bisher nicht be schrieben sind, ist der Verlauf der Reaktion auch aus dem Grunde überraschend, weil nicht vorauszusehen war,
dass die heteronu- cleare Sulfogruppe unverändert bleiben würde. Die auf diese Weise hergestellten Aryl- aminoanthrachinondisulfosäuren zeigen fär- berisch sehr hervorragende Eigenschaften; sie eignen sich infolge ihrer ausgezeichneten Löslichkeit ebensowohl zum Färben, als auch zum Drucken von Wolle; die damit erzielten Färbungen zeigen sehr klare, blaue bis grünblaue Nuancen von hervorragender Licht echtheit.
Das vorliegende Verfahren betrifft die Darstellung eines leicht wasserlöslichen Farb stoffes der Anthrachinonreihe, der durch Behandeln von 1-Amino-2-brom-4-anilido- anthrachinon-8-sulfosaurem Natrium mit wäs seriger Kaliumsulfitlösung in Gegenwart eines organischen Lösungsmittels erhalten wird.
Beispiel 10 Teile 1-Amino-2-brom-4-anilidoanthra- chinon-8-sulfosaures Natrium, 40 Teile Phenol und 20 Volumteile Kaliumsulfitlösung 33 %ig werden im Autoklaven so lange auf<B>180</B> erhitzt, bis kein unverändertes Ausgangs material mehr nachzuweisen ist.
Hierauf wird das Phenol mit einem or ganischen Lösungsmittel, zum Beispiel Benzol, extrahiert und der Farbstoff abfiltriert. Er fällt in Form von schönen, kleinen Kristallen mit Bronzeglanz aus und besteht aus 1- Amino-4-anlilidoantbrachirron 2,8-disulfosäure. In trockenem, gemahlenem Zustande stellt er ein dunkelblaues Pulver dar. Dasselbe ist in Wasser leicht mit klarblauer Farbe löslich. In Schwefelsäure löst sich der Farbstoff mit schwach grüngrauer Farbe, die auf Zusatz von Borsäure stumpf blau wird. In Salzsäure löst er sich mit rotvioletter Farbe; in kaltem Benzol und Äthylacetat ist er unlöslich.
Er färbt auf Wolle ein sehr reines Blau von vorzüglichen Echtheiten und besonders von hervorragender Lichtechtheit. Der Ton ändert sich nicht im künstlichen Licht.
Process for the preparation of an easily water-soluble dye of the anthraquinone line. In the patent specification no. 71038 </B> and the additional patent no. 71656 processes are described by which the halogen atom in 1-amino-2-halo-4-arylaminoanthraquinorren and their sulfonic acids by treatment with sulfites is counteracted the sulfo group is exchanged.
For example, 1-amino-2-bromo-4-p-tolylaminoanthraquinone is refluxed with a solution of galium sulfite in water with the addition of phenol, until there is no more increase in the formation of water-soluble dyes.
It has now been found that technically very valuable nucleus-substituted polysulphonic acids can be obtained from arylaminoanthraquinones (for example di- and trisulphonic acids) if the, ß-halogen derivatives of the arylaminoanthraquinones sulphated heteronuclearly in the α- or P-position with sulfite are added treated with phenol or similar substances.
Products can also be used which contain an acylamino group or some other substituent in the arylamino radical. Apart from the fact that such disulfonic acids, which contain the sulfo groups distributed on both benzene nuclei in the anthrachinone, have not yet been described, the course of the reaction is also surprising for the reason that it could not be foreseen
that the heteronuclear sulfo group would remain unchanged. The arylaminoanthraquinone disulfonic acids prepared in this way show very excellent coloring properties; Because of their excellent solubility, they are suitable both for dyeing and printing wool; the colorations achieved in this way show very clear, blue to green-blue nuances of excellent light fastness.
The present process relates to the preparation of a readily water-soluble dye of the anthraquinone series, which is obtained by treating 1-amino-2-bromo-4-anilido-anthraquinone-8-sulfonic acid sodium with aqueous potassium sulfite solution in the presence of an organic solvent.
Example 10 parts of 1-amino-2-bromo-4-anilidoanthraquinone-8-sulphonic acid sodium, 40 parts of phenol and 20 parts by volume of 33% potassium sulphite solution are heated to 180 in the autoclave until none unchanged starting material has to be proven.
The phenol is then extracted with an organic solvent, for example benzene, and the dye is filtered off. It precipitates in the form of beautiful, small crystals with a bronze sheen and consists of 1-amino-4-anlilidoantbrachirron 2,8-disulfonic acid. In the dry, ground state it is a dark blue powder. It is easily soluble in water with a clear blue color. The dye dissolves in sulfuric acid with a pale green-gray color, which turns dull blue when boric acid is added. In hydrochloric acid it dissolves with a red-violet color; it is insoluble in cold benzene and ethyl acetate.
It dyes wool a very pure blue with excellent fastness properties and especially excellent lightfastness. The tone does not change in artificial light.
