Description

  

      Verfahren    zur Herstellung     eines    neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man     diazotierte        4-          Benzoylamino-2-amino-l-benzolsulf        osäure    mit  1-     (2'-Chlor    -5'-     sulfosäure)-phenyl-3-methyl-          5-pyrazolon    kuppelt. Der so     erhalteneFarbstoff     bildet ein gelbes Pulver. Er färbt Wolle aus  schwefelsaurem Bade in sehr gleichmässigen,  grüngelben Tönen.

   Die Färbungen sind sehr  gut licht-,     wasser-,    wasch- und     alkaliecht    und  halten der sauren Walke stand.  



  <I>Beispiel:</I>  29 Teile     1-(2'-Chlor-5'-sulfosäure)-phe-          nyl-3-methyl-5-pyrazolon    werden in 150     Tei-          lenWasser    mit 20 Teilen     calcinierter    Soda gelöst  mit Eis gekühlt und hierauf mit der     Diazo-          verbindung    aus 29,2 Teilen     4-Benzoylamino-          2-amino-l-benzolsulfosäure    versetzt. Der sich  bildende Farbstoff scheidet sich teilweise    aus.

   Durch Zusatz von Kochsalz wird die  Fällung     vervöllständigt,        dann,        wird        möglichst     neutral gestellt, filtriert und getrocknet.



      Process for the production of a new dye. It has been found that a new dye is obtained if diazotized 4-benzoylamino-2-amino-1-benzenesulfonic acid is used with 1- (2'-chloro -5'-sulfonic acid) -phenyl-3-methyl-5-pyrazolone clutch. The dye thus obtained forms a yellow powder. He dyes wool from sulfuric acid bath in very even, green-yellow tones.

   The dyeings are very light, water, wash and alkali-fast and withstand acidic milled wool.



  <I> Example: </I> 29 parts of 1- (2'-chloro-5'-sulfonic acid) -phenyl-3-methyl-5-pyrazolone are dissolved in 150 parts of water with 20 parts of calcined soda with ice cooled and then mixed with the diazo compound from 29.2 parts of 4-benzoylamino-2-amino-1-benzenesulfonic acid. The dye that forms is partially separated out.

   The precipitation is completed by adding sodium chloride, then the mixture is rendered as neutral as possible, filtered and dried.
