Description

  

  Verfahren zur Darstellung eines     o-Oxyazofarbstoifes.       Es wurde gefunden, dass durch Kuppeln  von 4     #        6-Dinitro-2-diazo-l-oxybenzol    mit -     8-          Chlor-l-oxynaphtalin-5-sulfosäure    ein Farb  stoff erhalten wird, der auf urgebeizter Wolle  ein     Korinth    gibt und dessen Chromlack dunkel  grün ist.  



  <I>Beispiel:</I>  Die aus 19,9 Teilen 4     #        6-Dinitro=2-amino-          1-oxybenzol,    50 Teilen Salzsäure von 12  <I>136</I>  und 6,9 Teilen     Natriumnitrit    bereitete     Diazo-          verbindung    lässt man in eine durch Soda       alkälisch    gehaltene Lösung von 25,9 Teilen       8-Chlor-l-oxynaphtalir-5-sulfosäure        einlaufen.     Nach beendeter Kupplung salzt man den         Farbstoff    aus und arbeitet ihn in der üb  lichen Weise auf.



  Process for the preparation of an o-oxyazo dye. It has been found that by coupling 4 # 6-dinitro-2-diazo-1-oxybenzene with - 8-chloro-1-oxynaphthalene-5-sulfonic acid, a dye is obtained which gives a corinth to originally stained wool and its chrome varnish is dark green.



  <I> Example: </I> The diazo prepared from 19.9 parts of 4 # 6-dinitro = 2-amino-1-oxybenzene, 50 parts of hydrochloric acid of 12 <I> 136 </I> and 6.9 parts of sodium nitrite - The compound is allowed to run into a solution of 25.9 parts of 8-chloro-1-oxynaphthalene-5-sulfonic acid kept alkaline by soda. After the coupling has ended, the dye is salted out and worked up in the usual manner.
