Description

  

  Verfahren zur Herstellung eines sauren Farbstoffes der     Anthrachinonreihe.       Das vorliegende Patent betrifft ein Ver  fahren zur Herstellung eines sauren Farb  stoffes der     Anthrachinonreihe    und ist dadurch  gekennzeichnet, dass man     1-amino-4-broman-          thrachinon-2-sulfonsaures    Kalium mit     p-Ben-          zoylmethylaminoanil.in    kondensiert.  



  Im folgenden Beispiel bedeuten Teile     Ge-          wichtsteile.     



  <I>Beispiel:</I>  8,4 Teile     1-amino    - 4 -     bromanthrachinon-2-          sulfonsaures    Kalium, 9 Teile     p-Benzoyl-me-          thyl-aminoanilin,    10 Teile     Natriumbicarbonat,     0,1 Teil Kupferbronze und 0,3 Teil     Kupfer-          chlorür    werden in 50 Teilen Alkohol und  250 Teilen Wasser aufgeschlämmt und die  blasse unter Rühren während 6 Stunden auf  70  erhitzt.  



  Die blau gewordene Kondensationsmasse  wird auf übliche Weise aufgearbeitet und lie  fert nach dem Trocknen ein blaues     Farbst.off-          pulver,    das sich in Wasser mit lebhaft blauer  Farbe löst. Die Lösung in konzentrierter  Schwefelsäure ist blaugrün, beim Zusatz von  wenig     Paraformaldehyd    tritt ein Umschlag  nach grasgrün ein.  



  Der neue Farbstoff färbt Wolle, Seide und  andere tierische Fasern sowie künstliche Fa  sern, wie z. B. Nylon, in schönen blauen Tönen  an. Die Färbungen sind von sehr guter Licht-         echtheit,    sehr guter Wasch- und Schweissecht  heit und guter     Walkechtheit.  



  Process for the preparation of an acidic dye of the anthraquinone series. The present patent relates to a process for the production of an acidic dye of the anthraquinone series and is characterized in that 1-amino-4-bromanthrachinone-2-sulfonic acid potassium is condensed with p-benzoylmethylaminoanil.in.



  In the following example, parts mean parts by weight.



  <I> Example: </I> 8.4 parts of 1-amino - 4 - bromoanthraquinone-2-sulfonic acid potassium, 9 parts of p-benzoyl-methyl-aminoaniline, 10 parts of sodium bicarbonate, 0.1 part of copper bronze and 0, 3 parts of copper chloride are suspended in 50 parts of alcohol and 250 parts of water and the pale is heated to 70 for 6 hours while stirring.



  The condensation mass, which has turned blue, is worked up in the usual way and, after drying, produces a blue dye powder which dissolves in water with a vivid blue color. The solution in concentrated sulfuric acid is blue-green; if a little paraformaldehyde is added, it changes to grass-green.



  The new dye dyes wool, silk and other animal fibers and artificial fibers, such as. B. Nylon, in beautiful blue tones. The dyeings have very good light fastness, very good wash and perspiration fastness and good flexing fastness.
