Description

  

  Verfahren zur Darstellung eines     o-Oxyazofarbstoffes.       Es wurde gefunden, dass durch Kuppeln  von     3.4.6-Trichlor-2-diazo-l-oxybenzol    mit       8-Chlor-l-oxynaphtalin-5-sulfosäure    ein Farb  stoff erhalten wird, der auf Wolle mit     Hilfe     von Chrombeizen klare blaue Färbungen von  vorzüglicher Echtheit liefert.  



  <I>Beispiel:</I>  Die aus 21 Teilen     3.4.6-Trichlor-2-          amino-l-oxybenzol,    50 Teilen Salzsäure von  12       B6    und 6,9 Teilen     Natriumnitrit    bereitete       Diazoverbindung    lässt man in eine durch Soda  alkalisch gehaltene Lösung von 25,9 Teilen       8-Chlor-l-oxynaphtalin-5-sulfosäure    einlau  fen. Nach beendeter Kupplung     wird    der    Farbstoff in der üblichen Weise aufgear  beitet.



  Process for the preparation of an o-oxyazo dye. It has been found that by coupling 3.4.6-trichloro-2-diazo-l-oxybenzene with 8-chloro-l-oxynaphthalene-5-sulphonic acid, a dye is obtained that produces clear blue colors on wool with the help of chrome stains excellent authenticity.



  <I> Example: </I> The diazo compound prepared from 21 parts of 3.4.6-trichloro-2-amino-1-oxybenzene, 50 parts of hydrochloric acid of 12 B6 and 6.9 parts of sodium nitrite is left in a solution kept alkaline by soda of 25.9 parts of 8-chloro-1-oxynaphthalene-5-sulfonic acid enter. After coupling has ended, the dye is worked up in the usual way.
