Description

  

  Verfahren zur Herstellung eines sauren     Wollfarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines sauren     Woll-          farbstoffes,    dadurch gekennzeichnet, dass man  1-     Amino    - 4 -     bromanthrachinon-    2 -     sulfonsäure     mit     m-Aminobenzylacetamid    kondensiert.  



  Der so erhaltene Farbstoff stellt ein dunkel  blaues Pulver dar, das sich in konzentrierter  Schwefelsäure mit     blaustichiggrüner    Farbe  löst, die auf Zusatz von     Paraformaldehyd     nach     Gelbstichiggmün    umschlägt, und färbt  Wolle aus saurem Bade in klaren und sehr  egalen     rotstichig    blauen Tönen von guter  Lichtechtheit.  



  <I>Beispiel:</I>  40 Teile     1-Amino-4-bromanthrachinon-2-          sulfonsäure    werden in etwa 4000 Teilen  Wasser gelöst und mit 50 Teilen des schwefel  sauren     Salzes    des     m-Amino-benzyl-acetamids,     84 Teilen     Natriumbicarbonat    und 4 Teilen       Kupferchlorür    versetzt. Die Lösung wird meh-         rere    Stunden auf     90-951    C erhitzt. Ist die       Farbstoffbildung    beendet, so wird filtriert und  der gebildete     Farbstoff        ausgesalzen    und ge  trocknet.



  Process for the production of an acidic wool dye. The present patent relates to a process for the production of an acidic wool dye, characterized in that 1-amino-4-bromoanthraquinone-2-sulfonic acid is condensed with m-aminobenzylacetamide.



  The dye thus obtained is a dark blue powder which dissolves in concentrated sulfuric acid with a bluish green color, which changes to Gelbstichmün on addition of paraformaldehyde, and dyes wool from an acid bath in clear and very level reddish blue shades of good lightfastness.



  <I> Example: </I> 40 parts of 1-amino-4-bromoanthraquinone-2-sulfonic acid are dissolved in about 4000 parts of water and mixed with 50 parts of the sulfuric acid salt of m-amino-benzyl-acetamide, 84 parts of sodium bicarbonate and 4 parts of copper chloride added. The solution is heated to 90-951 ° C. for several hours. When the dye formation has ended, it is filtered and the dye formed is salted out and dried.
