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.

PATENTANSPRUCH: Verfahren zur Darstellung eines Farb stoffes der Antbrachinonreibe, dadurch ge kennzeichnet, dass man eine in 4-Stellungeinen reaktionsfähigen Substituenten aufweisende 1-Aminoanthrachinon-2-sulfosäure und Penta- menthylenamin aufeinander einwirken lässt. Der so erhaltene neue Farbstoff bildet blaue Nadeln, die sich in Wasser blau lösen, und färbt Wolle aus saurem Bade klarblau an. Claim: A process for the preparation of a dye of the antbrachinone grater, characterized in that a 1-aminoanthraquinone-2-sulfonic acid, which has a reactive substituent in the 4-position, and penta-menthyleneamine are allowed to act on one another. The new dye thus obtained forms blue needles, which dissolve blue in water, and stains wool from an acid bath clear blue.
