Description

  

  Verfahren zur Darstellung eines neuen     Anthraehinonfarbstoffes.       Das vorliegende Verfahren     betrifft    die  Darstellung eines neuen     Anthrachinonfarb-          stoffes    und ist dadurch gekennzeichnet, dass  man     1-Amino-4    - (2', 4',     6'-trimethyianilido)-          anthrachinon-2-sulfonsäure    in Gegenwart von       Atzkali    mit     Äthylenglykolmonoäthyläther     kondensiert und die erhaltene Verbindung       sulfiert.     



  <I>Beispiel:</I>  In 500 Teilen     Äthylenglykolmonoätliyl-          äther    werden 20 Teile     Ätzkali    heiss gelöst.  In die Lösung trägt man 50 Teile des Farb  stoffes der Formel  
EMI0001.0014     
    ein und rührt bei<B>100-1050</B> bis eine in Al  kohol gezogene Probe nicht mehr röter wird.    Man verdünnt mit Alkohol und lässt abkühlen.  Die auskristallisierte Base wird wie üblich  aufgearbeitet.  



  10 Teile der Base werden in 50 Teilen  Monohydrat gelöst und unterhalb<B>300</B> mit  15 Teilen schwachem     Oleum    versetzt. Nach  kurzem Rühren bei 30  ist eine Probe wasser  löslich. Man fällt den Farbstoff durch Ein  giessen in     Eis-Salzwassermischung,    saugt ihn  ab und stellt ihn in Wasser neutral. Nach  Absaugen und Trocknen erhält man einen  Farbstoff, der Wolle lebhaft rotviolett färbt.  Er besitzt die Formel  
EMI0001.0017     
    Die Färbung ist licht-, wasch- und schweiss  echt.



  Process for the preparation of a new anthraquinone dye. The present process relates to the preparation of a new anthraquinone dye and is characterized in that 1-amino-4 - (2 ', 4', 6'-trimethyianilido) - anthraquinone-2-sulfonic acid is condensed in the presence of caustic potash with ethylene glycol monoethyl ether and the compound obtained is sulfated.



  <I> Example: </I> 20 parts of caustic potash are dissolved in 500 parts of ethylene glycol monoethyl ether. 50 parts of the dye of the formula are carried into the solution
EMI0001.0014
    and stir at <B> 100-1050 </B> until a sample taken in alcohol no longer turns red. Dilute with alcohol and allow to cool. The base which has crystallized out is worked up as usual.



  10 parts of the base are dissolved in 50 parts of monohydrate and 15 parts of weak oleum are added below <B> 300 </B>. After brief stirring at 30, a sample is water-soluble. The dye is precipitated by pouring it into an ice-salt water mixture, suctioned off and placed in water to be neutral. After suctioning off and drying, a dye is obtained which dyes wool vividly red-violet. He owns the formula
EMI0001.0017
    The color is light, washable and sweat-proof.
