Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       . Es wurde gefunden, dass man einen neuen       Azofarbstoff    herstellen kann, wenn man die       Diazoverbindung    der     4-Amino-1-benzolsulfo-          säure    mit     1-(3'-Sulfamido-6'-methyl)-3-me-          thyl-5-pyrazoIon    kuppelt. Der neue     Azofarb-          stoff    bildet ein gelbes Pulver. Er färbt  Wolle aus saurem Bade gleichmässig und  lichtecht grüngelb.  



       Beispiel:     Die     Diazoverbindung,    hergestellt aus 173  Teilen der     4-Amino-l-benzolsulfosäure,    wird  in eine abgekühlte wässerige Lösung von  255 Teilen     1-(3'-Sulfamido-6'-methyl)-3-me-          thyl-5-pyrazolon-3-carbonsäure    und 150 Tei  len Soda eingetragen. Die Kupplung geht    sehr rasch vor sich, der gebildete Farbstoff  wird durch     Aussalzen    gefällt, dann filtriert  und getrocknet.



  Process for the production of a new azo dye. . It has been found that a new azo dye can be produced if the diazo compound of 4-amino-1-benzenesulfonic acid is mixed with 1- (3'-sulfamido-6'-methyl) -3-methyl-5-pyrazolone clutch. The new azo dye forms a yellow powder. It dyes wool from acid baths evenly and lightfast green-yellow.



       Example: The diazo compound, prepared from 173 parts of 4-amino-1-benzenesulfonic acid, is dissolved in a cooled aqueous solution of 255 parts of 1- (3'-sulfamido-6'-methyl) -3-methyl-5-pyrazolone -3-carboxylic acid and 150 parts of soda entered. The coupling takes place very quickly, the dye formed is precipitated by salting out, then filtered and dried.
