Description

  

  Verfahren zur Herstellung eines neuen     Farbstoffes    der     Anthrachinonreihe.       Es wurde gefunden, dass man einen neuen  Farbstoff der     Anthrachinonreihe    erhält,  wenn man auf 1 Hol     Cyanurehlorid    1 Hol  1-     Amino-4-(4'-amino-diphenyl)-amino-anthra.-          chinon-2-sulfosäure    und 2 Hol     Methylamin     derart einwirken lässt,

   dass ein Halogenatom  des     Cyanurchlorides    durch 1 Hol des     Di-          aminoanthrachinonderivates    und die zwei  andern Halogenatome durch je 1 Hol     Methyl-          amin    ausgetauscht werden.  



  Der neue Farbstoff bildet ein dunkles  Pulver, das sich in Wasser mit blauer Farbe  löst und Baumwolle,     Viskose,    Wolle oder  Seide in     grünstichigblauen    Tönen von vor  züglicher Lichtechtheit färbt.    <I>Beispiel:</I>    18,5 Teile     Cyanurchlorid    werden in 800  Teilen Wasser fein suspendiert. Zu dieser       Suspension    giesst man eine neutrale Lösung  von 48,5 Teilen     1-Amino-4-(4'-amino-diphe-          nyl)-amino-anthrachinon-2-sulfonsäure    in       120O    Teilen Wasser.

   Man rührt bei     2,0'     <B>8</B>     -bis    4     .Sunden    und giesst     allmählieh    50 Teile       10%ige        Nat#3,rbanatlösung    dazu, so dass    die Reaktion immer neutral bleibt. Dann  gibt man 40 Teile einer 40 %     igen        Nethyl-          aininlösung    dazu. Man erhöht nun die Tem  peratur allmählich bis auf 90  , macht durch  Zugabe von Natriumkarbonat alkalisch und  salzt den gebildeten     Farbstoff    aus..



  Process for the production of a new dye of the anthraquinone series. It has been found that a new dye of the anthraquinone series is obtained if one pole of cyanuric chloride 1 pole of 1-amino-4- (4'-amino-diphenyl) -amino-anthra.-quinone-2-sulfonic acid and 2 poles of methylamine are used let it take effect

   that one halogen atom of the cyanuric chloride is exchanged for 1 hol of the di-aminoanthraquinone derivative and the two other halogen atoms with 1 hol of methylamine each.



  The new dye forms a dark powder that dissolves in water with a blue color and dyes cotton, viscose, wool or silk in greenish-blue tones that are extremely lightfast. <I> Example: </I> 18.5 parts of cyanuric chloride are finely suspended in 800 parts of water. A neutral solution of 48.5 parts of 1-amino-4- (4'-aminodiphenyl) -amino-anthraquinone-2-sulfonic acid in 120O parts of water is poured into this suspension.

   The mixture is stirred for 2.0 '8 to 4 hours and 50 parts of 10% sodium bicarbonate solution are gradually poured in, so that the reaction always remains neutral. Then 40 parts of a 40% strength ethyl ainine solution are added. The temperature is now gradually increased to 90, made alkaline by adding sodium carbonate and salting out the dye formed.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes der Anthrachinonreihe, dadurch g ekennzeichnet, dass man auf 1 Hol Cyanur- chlorid 1 Mol 1-Amino-4-(4'-amino-diphenyl)- amino-anthrachinon-2-sulfosäure und 2 Hol Methylamin derart einwirken lässt, dass ein Halogenatom des Cyanurchlorides -durch 1 Hol des Diaminoanthrachinonderivates und die zwei andern Halogenatome durch je 1 Hol Methylamin ausgetauscht werden. PATENT CLAIM: Process for the preparation of a new dye of the anthraquinone series, characterized in that 1 mol of 1-amino-4- (4'-amino-diphenyl) -amino-anthraquinone-2-sulfonic acid and 2 hol of cyanuric chloride are used Allow methylamine to act in such a way that one halogen atom of the cyanuric chloride is exchanged for 1 hol of the diaminoanthraquinone derivative and the two other halogen atoms are replaced by 1 hol of methylamine each. Der neue Farbstoff bildet ein dunkles Pulver, das sich in Wasser mit blauer Farbe löst und Baumwolle, Viskose, Wolle oder Seide in grünstichigblauen Tönen von vor züglicher Lichtechtheit färbt. The new dye forms a dark powder that dissolves in water with a blue color and dyes cotton, viscose, wool or silk in greenish-blue tones that are extremely lightfast.
