Description

  

  Verfahren zur     Herstellunn    eines     direktziehenden        o-Oxyazofarbstoftes.       Es wurde gefunden, dass durch Kuppeln  von 1     Mol.        diazotiertem        o-Anisidin        und    1     Mol.          diazotiertem        2-Amino-4-nitro-l-oxybenzol        nut     1     Mol.    Harnstoff der     2-Amino-5-oxy         aplitalii:

  -          7-sulfosäure    ein     direktziehender        o-Oxyazo-          farbstoff    erhalten wird, welcher Baumwolle  in licht- und     alkalieinpfindliclien    violetten  Tönen anfärbt. Durch     dachkupfern    oder noch  besser durch Färben in der für     direktziehende     Farbstoffe üblichen Weise unter     Zusatz        von     Kupferverbindungen zum Bade werden leer  vorragend licht- und     alkaliechte        Bordeaux     Töne erhalten.  



  <I>Beispiel:</I>  12,3 kg     o-Anisidin    und 15,4 kg     2-Amino-          4-nitro-l-oxybenzol    werden     diazotiert    und  diese nacheinander in eine Lösung von 50,4 kg       Harnstoff'    der     2-Aniino-5-oxynaphteilin-7-sulfo-          säure    und 50 kg     Soda,        einfliel, eii    gelassen.    Nach 12 Stunden wird der     Farbstoff        aus--e-          .salzen.        filtriert    und     getrochnet.  



  Process for the production of a substantive o-oxyazo dye. It was found that by coupling 1 mole of diazotized o-anisidine and 1 mole of diazotized 2-amino-4-nitro-1-oxybenzene, 1 mole of urea of 2-amino-5-oxy aplitalii:

  - 7-sulfonic acid a substantive o-oxyazo dye is obtained which dyes cotton in light- and alkali-sensitive violet tones. Roof copper or, even better, dyeing in the manner customary for substantive dyes with the addition of copper compounds to the bath results in excellent light- and alkali-fast Bordeaux tones.



  <I> Example: </I> 12.3 kg of o-anisidine and 15.4 kg of 2-amino-4-nitro-l-oxybenzene are diazotized and these are successively converted into a solution of 50.4 kg of urea 'of the 2- Aniino-5-oxynaphpartin-7-sulfonic acid and 50 kg of soda were poured in and left. After 12 hours the dyestuff is salted out. filtered and dried.
