Description

  

  Verfahren zur Herstellung eines     o-OxSazofarbstoffes.       Es wurde gefunden, dass durch Kuppeln  von 3 - 4 .     6-Trichlor-2-diazo-l-oxybenzol    mit       1-Naphtol-4-sulfosäure    ein     Farbstoff    erhalten  wird, der auf Wolle mit Hilfe von Chrom  beizen violette,     gleichmässige    walk-, licht- und  reibechte Nuancen liefert.

           Beispiel:       Die aus 21,3 Teilen 3 - 4     #        6-Trichlor-          2-amino-l-oxybenzol    bereitete     Diazoverbindung     lässt man in eine durch Soda alkalisch ge  haltene Lösung von 22,4 Teilen     1-Oxynaph-          talin-4-sulfosäure    einlaufen. Nach beendeter    Kupplung salzt man den     Farbstoff    aus und       arbeitet    ihn in der üblichen Weise auf.



  Process for the preparation of an o-oxazo dye. It was found that by coupling 3 - 4. 6-Trichlor-2-diazo-1-oxybenzene with 1-naphthol-4-sulfonic acid a dye is obtained, which on wool with the help of chromium stains provides violet, uniform nuances which are fast to kneading, light and rubbing.

           Example: The diazo compound prepared from 21.3 parts of 3-4 # 6-trichloro-2-amino-1-oxybenzene is allowed to run into a solution of 22.4 parts of 1-oxynaphthalene-4-sulfonic acid which is kept alkaline by soda . After coupling has ended, the dye is salted out and worked up in the usual way.

PATENTANSPRUCH: Verfahren zur Darstellung eines o-Oxy- azofarbstoffes, der auf Wolle mit Hilfe von Chrombeizen gleichmässige walk-, licht- und reibechte violette Nuancen liefert, dadurch gekennzeichnet, dass man 3 # 4 . 6-Trichlor- 2-diazo-l-oxybenzol mit 1-Oxynaphtalin-4- sulfosäure kuppelt. PATENT CLAIM: Process for the preparation of an o-oxy azo dye which, with the help of chrome stains, delivers uniform violet nuances that are fast to knead, light and rub-fast, characterized in that 3 # 4. 6-Trichloro-2-diazo-1-oxybenzene couples with 1-oxynaphthalene-4-sulfonic acid.
