Description
Verfahren zur Herstellung von quartären Dicoeramidoninen Es wurde gefunden, daß man Dicoeramidonine durch Behandlung mit molaren Mengen Dimethylsulfat in monoquartäre Salze überführen kann.Process for the preparation of quaternary dicoeramidonines It has been found that one dicoeramidonine by treatment with molar amounts of dimethyl sulfate can convert into mono-quaternary salts.
Die Herstellung der als Ausgangsmaterial verwendeten Dicoeramidonine ist bekannt. Sie können z. B. aus 1,4- bzw. 1,5-Diarylido-anthrachinonen durch doppelten Dicoeramidoninringschluß mit Hilfe von Schwefelsäure erhalten werden. Die für das erfindungsgemäße Verfahren geeigneten Verbindungen können sowohl im Anthrachinonrest als auch im Arylrest der als Ausgangsmaterial verwendeten Diarylido-anthrachinone substituiert sein, z. B. durch Alkyl-, Oxy-, Alkoxy- oder Halogenreste.The production of the dicoeramidonine used as a starting material is known. You can e.g. B. from 1,4- or 1,5-diarylido-anthraquinones by double Dicoeramidonine ring closure can be obtained with the aid of sulfuric acid. The one for that Compounds suitable for the process according to the invention can be present both in the anthraquinone radical as well as in the aryl radical of the diarylido-anthraquinones used as starting material be substituted, e.g. B. by alkyl, oxy, alkoxy or halogen radicals.
Die Quaternierung mittels Dimethylsulfat kann in der Weise erfolgen, daß man eine Lösung bzw. Suspension der Dicoeramidonine in einem Lösungsmittel, wie Chlorbenzol, o-Dichlorbenzol oder Nitrobenzol, mit 1 Mol Dimethylsulfat auf etwa 100 bis 150° C erwärmt. Überraschenderweise werden bei der Ouaternierung nur monoquartäre Verbindungen erhalten, die sich häufig gut kristallisiert abscheiden und dann in bekannter Weise isoliert werden können.The quaternization by means of dimethyl sulfate can take place in the manner that a solution or suspension of the dicoeramidonine in a solvent, such as chlorobenzene, o-dichlorobenzene or nitrobenzene, with 1 mol of dimethyl sulfate heated about 100 to 150 ° C. Surprisingly, only Obtain mono-quaternary compounds, which are often deposited well crystallized and can then be isolated in a known manner.
Die durch das neue Verfahren erhältlichen Verbindungen sind sehr tief gefärbt und lösen sich überraschenderweise, obwohl sie in einem verhältnismäßig großen Molekül nur eine wasserlöslichmachende Gruppe enthalten, glatt in Wasser. Aus den wäßrigen Lösungen werden Polymerisate bzw. Mischpolymerisate von Acrylnitril in olivgrünen bis grauen Tönen angefärbt. Die Ausfärbungen besitzen eine ausgezeichnete Lichtechtheit.The connections obtainable by the new process are very deep colored and surprisingly dissolve, although in a proportionate manner large molecule contain only one water-solubilizing group, smoothly in water. The aqueous solutions become polymers or copolymers of acrylonitrile colored in olive green to gray tones. The colors are excellent Lightfastness.
Beispiel 38 Gewichtsteile des Dicoeramidonins aus 1,4-p-Ditoluido,anthrachinon und 250 Gewichtsteile Chlorbenzol werden auf 120° C erhitzt und bei dieser Temperatur innerhalb von 2 Stunden mit 12,5 Gewichtsteilen Dimethylsulfat versetzt. Das Reaktionsprodukt scheidet sich allmählich in olivfarbenen Kristallen ab. Nach Beendigung der Reaktion läßt man erkalten, saugt ab, wäscht mit Benzol und trocknet. Das erhaltene monoquartäre Produkt löst sich mit grüner Farbe in Wasser und färbt daraus Polyacryinitrilfasern in vorzüglich lichtechten olivgrünen Tönen an.EXAMPLE 38 parts by weight of dicoeramidonine from 1,4-p-ditoluido, anthraquinone and 250 parts by weight of chlorobenzene are heated to 120 ° C. and 12.5 parts by weight of dimethyl sulfate are added at this temperature over the course of 2 hours. The reaction product gradually separates out in olive-colored crystals. When the reaction has ended, the mixture is allowed to cool, filtered off with suction, washed with benzene and dried. The mono-quaternary product obtained dissolves in water with a green color and dyes polyacrylonitrile fibers from it in excellent lightfast olive-green tones.
Ähnliche Farbstoffe erhält man aus den Dicoeramidoninen, die sich durch doppelten Ringschluß aus 1,4-Dianilido- und 1,4-Di-(3'-chlor-4'-methylanilido)-anthrachinon ergeben, während das Dicoeramidonin aus 5,6-Dioxy-1,4,ditoluido-anthrachinon einen die Polyacrylnitrilfaser graufärbenden Farbstoff liefert.Similar dyes are obtained from the Dicoeramidoninen, which by double ring closure from 1,4-dianilido- and 1,4-di- (3'-chloro-4'-methylanilido) -anthraquinone result, while the Dicoeramidonin from 5,6-Dioxy-1,4, ditoluido-anthraquinone one the polyacrylonitrile fiber provides gray coloring dye.
Das Di-coeramidonin aus 1,5-Ditoluido-anthrachinon liefert unter den gleichen Bedingungen einen ebenfalls wasserlöslichen Farbstoff, der auf Pölyacrylnitrilfaser grünstichiggraue Färbungen sehr guter Lichtechtheit ergibt.The di-coeramidonin from 1,5-ditoluido-anthraquinone provides among the under the same conditions a water-soluble dye based on polyacrylonitrile fiber greenish gray dyeings result in very good lightfastness.
