Description

  

  Verfahren zur Herstellung eines     Azofarbstoffes.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Azofarbstoffes,     dadurch gekennzeichnet, dass man dianotiertes       4-Chlor-2-amino-l-oxybenzol    mit     1-(P-Chlor-          propionylamino)    - 7 -     oxynaphthalin    - 3 -     salfon-          säure    kuppelt.  



  Der so erhaltene Farbstoff ist ein wasser  lösliches, violettes Pulver und färbt Wolle  aus saurem Bade in roten Tönen, die beim       Nachehromieren    in ein     rotstichiges    Grau von  hervorragender Walk- und Lichtechtheit und  gutem     Egalisiervermögen    übergehen.    <I>Beispiel:</I>    14,3 Teile     4-Chlor-2-amino-l-oxybenzol    wer  den in der üblichen Weise dianotiert und die  erhaltene     Diazolösung    wird mit einer über  schüssiges     Natriumcarbonat    enthaltenden Lö  sung von 33 Teilen 1-(P-Chlorpropionylamino)-         7-oxynaphthalin-3-sulfonsäure    vereinigt.

   Nach  beendeter     Kuppelung    wird der gebildete Farb  stoff abgeschieden und getrocknet.



  Process for the preparation of an azo dye. The present patent relates to a process for the production of an azo dye, characterized in that dianotated 4-chloro-2-amino-1-oxybenzene is coupled with 1- (P-chloropropionylamino) - 7 - oxynaphthalene - 3 - nitrous acid .



  The dye obtained in this way is a water-soluble, violet powder and dyes wool from an acid bath in red shades which, when retouched, turn into a reddish gray of excellent mill and lightfastness and good leveling properties. <I> Example: </I> 14.3 parts of 4-chloro-2-amino-l-oxybenzene who are dianotized in the usual way and the diazo solution obtained is mixed with a solution of 33 parts 1- ( P-chloropropionylamino) - 7-oxynaphthalene-3-sulfonic acid combined.

   After the coupling is complete, the dye formed is deposited and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines Azofarb- stoffes, dadurch gekennzeichnet, dass man di anotiertes 4-Chlor-2-amino-l-oxybenzol mit 1-(ss-Chlorpropionylamino)-7-oxynaphth alin - 3 sulfonsäure kuppelt. Der so erhaltene Farbstoff ist ein wasser lösliches, violettes Pulver und färbt Wolle aus saurem Bäde in roten Tönen, die beim Nachchromieren in ein rotstichiges Grau von hervorragender Walk- und Lichtechtheit und gutem Egalisiervermögen übergehen. PATENT CLAIM: Process for the production of an azo dye, characterized in that di-anotated 4-chloro-2-amino-1-oxybenzene is coupled with 1- (ss-chloropropionylamino) -7-oxynaphthalene-3 sulfonic acid. The dyestuff thus obtained is a water-soluble, violet powder and dyes wool from acidic baths in red shades which, on post-chrome plating, turn into a reddish gray with excellent mill and lightfastness and good leveling properties.
