Description
Verfahren zur Darstellung eines Farbstoffes der Anthrachinonreihe. Durch das Hauptpatent ist ein Verfahren zier Darstellung der in besonders klaren und lichtechten Tönen färbenden 1-Amino-4-he- salrydroanilidoanthrachirion- 2-sulfosäure ge schützt, das dadurch gekennzeichnet ist, dass man eine in 4-Stellung einen reaktionsfähigen Substituenten aufweisende 1-Aminoanthra- chinon-2-sulfosäure und Hegahydroanilin auf einander einwirken lässt.
Es wurde nun gefunden, dass man eben falls einen Farbstoff erhält, wenn man auf eine in 4-Stellung einen reaktionsfähigen Substituenten aufweisende 1-Aminoarrthrachi- non-2-sulfosäure Pentamethylenamin einwir ken lässt. Der so erhaltene neue Farbstoff bildet blaue Nadeln, die sich in Wasser blau lösen, und färbt Wolle aus saurem Bade klarblau an.
<I>Beispiel:</I> 20 Gewichtsteile 1-Amino-4-bromanthra- chinon-2-sulfosäure, 12 Gewichtsteile Soda und 60 Gewichtsteile Pentamethylenamin werden unter Zusatz von einem Gewichts teile Kupfersulfat in 900 Gewichtsteilen Wasser und 100 Gewichtsteilen Alkohol ge löst und 2 Stunden lang unter Rückfluss- kühlung gekocht, wobei die Lösung sich blau färbt. Sodann wird der Alkohol und die überschüssige Base abdestilliert und der Farbstoff mit Kochsalz als kristallene Masse ausgefällt. Derselbe löst sich mit klarer blauer Farbe in Wasser und färbt Wolle in sehr klaren, lichtechten blauen Tönen gus saurem Bade an.
Process for the preparation of a dye of the anthraquinone series. The main patent is a method of decorative representation of the 1-amino-4-salrydroanilidoanthrachirion- 2-sulfonic acid, which is colored in particularly clear and lightfast tones, which is characterized in that one has a reactive substituent in the 4-position 1- Aminoanthraquinone-2-sulfonic acid and hegahydroaniline can act on each other.
It has now been found that a dye is also obtained if pentamethyleneamine is allowed to act on a 1-aminoarrthraquinone-2-sulfonic acid pentamethyleneamine which has a reactive substituent in the 4-position. The new dye thus obtained forms blue needles, which dissolve blue in water, and stains wool from an acid bath clear blue.
<I> Example: </I> 20 parts by weight of 1-amino-4-bromoanthraquinone-2-sulfonic acid, 12 parts by weight of soda and 60 parts by weight of pentamethylene amine are dissolved in 900 parts by weight of water and 100 parts by weight of alcohol with the addition of one part by weight of copper sulfate and refluxed for 2 hours, the solution turning blue. The alcohol and the excess base are then distilled off and the dye is precipitated as a crystalline mass with common salt. It dissolves in water with a clear blue color and stains wool in very clear, lightfast blue shades in acidic baths.
