Description

  

  Verfahren zur Herstellung einer     Monoazofarbstofl'sulfonsäure.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung einer     Monoazo-          farbstoffsulfonsäure,    dadurch gekennzeich  net, dass man die     Diazoverbindung    von 1       Aminobenzol-3-carbonsäure-di-(a-äthyl-n-          hexyl)-amid    mit     1-(2'-Chlor-6'-methyl-4'-          sulfophenyl)-3-methyl-5-pyrazolon    vereinigt.  



  Der so erhaltene Farbstoff ist in trocke  nem Zustand ein wasserlösliches gelbes  Pulver, besitzt ein sehr gutes Ziehvermögen  aus neutralem Bade und färbt Wolle in grün  stichig gelben Tönen von sehr guter Walk-,  Schweiss- und Lichtechtheit.  



  <I>Beispiel:</I>  37 Teile     1-Aminobenzol-3-carbonsäure-di-          (ai-äthyl-n-hexyl)-amid,        werden,        diazotiert.    Die  erhaltene     Diazolösung    lässt man in eine     soda-          alkalische    Lösung von 31 Teilen     1-(2-Chlor-          6'-        'methyl    -4' -     sulf        ophenyl)    - 3     -methyl    - 5 -pyr-         azolon    laufen.

   Der erhaltene Farbstoff     wird     abgeschieden     und    getrocknet.



  Process for the preparation of a monoazo dye sulfonic acid. The present patent relates to a process for the preparation of a monoazo dye sulfonic acid, characterized in that the diazo compound of 1 aminobenzene-3-carboxylic acid-di- (a-ethyl-n-hexyl) -amide with 1- (2'- Chloro-6'-methyl-4'-sulfophenyl) -3-methyl-5-pyrazolone combined.



  The dyestuff thus obtained is a water-soluble yellow powder when dry, has very good drawability from a neutral bath and dyes wool in green, pale yellow shades of very good mill, perspiration and lightfastness.



  <I> Example: </I> 37 parts of 1-aminobenzene-3-carboxylic acid-di- (ai-ethyl-n-hexyl) -amide are diazotized. The diazo solution obtained is run into a soda-alkaline solution of 31 parts of 1- (2-chloro-6'- 'methyl -4' -sulfophenyl) -3-methyl-5-pyrazolone.

   The dye obtained is deposited and dried.
