Description

  

  Verfahren zur Darstellung eines     o-Oxyazofarbstoffes.       Es wurde gefunden, dass durch Kuppeln  von     3.4.5-Trichlor-2-cliazo-l-oxybenzol    mit       8-Chlor-l-oxynaphtalin-5-sulfosäure    ein Farb  stoff erhalten wird, der .auf chromgebeizter  Wolle oder durch     Nachchromieren    der     in     saurem Bade entstehenden Färbungen, oder  beim Färben von Wolle im     Einbadverfahren     in Gegenwart von     Chromaten    und dissoziie  renden     Ammoniumsalzen    gleichmässige,     walk-,     licht-     -und    reibechte blaue Nuancen liefert.

           Beispiet:     Die aus 21 Teilen     3.4.5-Trichlar-2-          amino-l-oxybenzol,    50 Teilen Salzsäure von  12   De und 6,9 Teilen     Natriumnitrit    bereitete       Diazoverbindung        lässt    man in eine durch Soda  alkalisch gehaltene Lösung von 25,9 Teilen       8-Chlor-l-oxyna,phtalin-5-sulfosäure    einlau  fen. Nach     beendeter    Kupplung salzt man    .den Farbstoff aus und arbeitet ihn in der  üblichen Weise auf.



  Process for the preparation of an o-oxyazo dye. It has been found that by coupling 3.4.5-trichloro-2-cliazo-l-oxybenzene with 8-chloro-l-oxynaphthalene-5-sulfonic acid, a dye is obtained that can be used on chrome-stained wool or by re-chrome-plating in acidic Bath dyeing, or when dyeing wool in the single bath process in the presence of chromates and dissociating ammonium salts, provides uniform blue nuances that are fast to kneading, light and rub fast.

           Example: The diazo compound prepared from 21 parts of 3.4.5-Trichlar-2-amino-1-oxybenzene, 50 parts of hydrochloric acid of 12 De and 6.9 parts of sodium nitrite is left in a solution of 25.9 parts of 8- Chlorine-l-oxyna, phthaline-5-sulphonic acid enter. After coupling has ended, the dye is salted out and worked up in the usual way.
