Description

  

  Verfahren zur Darstellung eines     Azofarbstoffes.       Im Hauptpatent ist ein Verfahren zur     Dar-          stellung    eines     Azofarbstoffes    beschrieben, bei  dem     1-Phenyl-5-pyrazolon-3-carbonsäureainid     mit der     Diazoverbindung    aus der     1-Oxy-2-          amino-6-chlorberizol-4-sulfonsäure    gekuppelt  wird.  



  Es wurde nun gefunden, dass man einen  ähnlich wertvollen     Farbstoff    erhält, wenn man       1-I'henyl-5-pyrazolon-3-carbonsäureamid    mit  der     Diazoverbindung    aus der     1-Oxy-2-aniino-          4-chlorbenzol-6-sulfonsäure    kuppelt.  



  Der erhaltene     Farbstoff    liefert auf Wolle  orange Töne, die beim Nachbehandeln mit  chromabgebenden Mitteln ein sehr lichtechtes  und gut egalisierendes     Bordo    geben.    <I>Beispiel:</I>    Die auf übliche Weise hergestellte Lösung  der     Diazoverbindung    aus 223 Teilen     1-Oxy-2-          amirio-4-chlorbenzol-6-sulfonsäure    gibt man  zu einer     Lösung    von 210 Teilen 1-Phenyl-5-         pyrazolon-3-carbonsäui-eamidin        einerMischung     aus 250 Teilen     calcinierter    Soda und 1500 Teilen  Wasser.

   Sobald die Kupplung beendet ist,  wird der     Farbstoff    durch Zugabe von festem  Kochsalz     ausgesalzen    und in der üblichen  Weise aufgearbeitet.



  Process for the preparation of an azo dye. The main patent describes a process for the preparation of an azo dye in which 1-phenyl-5-pyrazolone-3-carboxylic acid amide is coupled with the diazo compound from 1-oxy-2-amino-6-chloroberizole-4-sulfonic acid.



  It has now been found that a similarly valuable dye is obtained if 1-I'henyl-5-pyrazolone-3-carboxamide is coupled with the diazo compound from 1-oxy-2-aniino-4-chlorobenzene-6-sulfonic acid.



  The dye obtained gives orange tones on wool which, on aftertreatment with chromium-releasing agents, give a very lightfast and well-leveling border. <I> Example: </I> The solution of the diazo compound prepared in the usual way from 223 parts of 1-oxy-2-amirio-4-chlorobenzene-6-sulfonic acid is added to a solution of 210 parts of 1-phenyl-5-pyrazolone -3-carbonsäui-eamidin a mixture of 250 parts of calcined soda and 1500 parts of water.

   As soon as the coupling has ended, the dye is salted out by adding solid common salt and worked up in the usual way.

PATENTANSPRUCH: Verfahren zur Darstellung eines Azofarb- stoffes, dadurch gekennzeichnet, dass man 1 Phenyl-5-pyrazolori-3-carbonsäureamid mit der Diazoverbindung aus der 1-Oxy-2-amirio-4- chlorbeiizol-6-sulfonsäure kuppelt. Der erhaltene Farbstoff liefert beim Färben auf Wolle orange Töne, die beim Nachbehan deln mit chromabgebenden Mitteln in ein sehr lichtechtes und gut egalisierendes Bordo über gehen. PATENT CLAIM: Process for the preparation of an azo dye, characterized in that 1 phenyl-5-pyrazolori-3-carboxamide is coupled with the diazo compound from 1-oxy-2-amirio-4-chlorobeiizole-6-sulfonic acid. When dyeing wool, the dye obtained provides orange tones which, when treated with chromium-releasing agents, change into a very lightfast and well-leveling Bordo.
