Description

  

  Verfahren zur Darstellung eines     o-Ogyazofarästoffes.       Es wurde gefunden, dass durch Kuppeln  von     3.4.6-Trichlor-2-diazo-l-oxybenzol    mit       1-Oxynaphtalin-5-sulfosäure    ein Farbstoff  erhalten wird, der mit Hilfe von Chrombei  zen auf Wolle violette Färbungen von guter       Walk-,    Licht- und Reibechtheit liefert.

      <I>Beispiel:</I>    Die aus 21,3 Teilen     3.4.6-Trichlor-2-          amino-l-oxybenzol    auf die übliche Weise be  reitete     Diazoverbindung    wird mit 25 Teilen       1-0xynaphtalin-5-sulfosalirem    Natrium in       s        odaalkalischer        Lösung        vereinigt.        Nach    been-         deter    Kupplung salzt man den Farbstoff     aus     und arbeitet ihn auf übliche     ZVeise    auf.



  Process for the preparation of an o-ogyazoarea. It has been found that by coupling 3.4.6-trichloro-2-diazo-1-oxybenzene with 1-oxynaphthalene-5-sulfonic acid, a dye is obtained which, with the help of chromium bites, has violet colorations of good fulling, light on wool - and rubbing fastness delivers.

      <I> Example: </I> The diazo compound prepared in the usual way from 21.3 parts of 3.4.6-trichloro-2-amino-1-oxybenzene is mixed with 25 parts of 1-oxynaphthalene-5-sulfosaline sodium in soda-alkaline Solution united. After coupling is complete, the dye is salted out and worked up in the usual way.
