Description

  

      Verfahren    zur Herstellung     eines    neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man     diazotierte     Farbstoff erhält, wenn man     diazotierte        4-          Acetamino-2-amino-l-benzolsulfosäure    mit 1  pyrazolon kuppelt. Der so erhaltene Farb  stoff bildet ein gelbes Pulver. Er färbt Wolle  aus schwefelsaurem Bade in sehr. gleich  mässigen, grüngelben Tönen. Die Färbungen  sind sehr gut licht-, Wasser- und     alkaliecht     und halten der sauren Walke stand.  



  <I>Beispiel:</I>  39 Teile     1-(-2'-Chlor-4'-sulfosäure)-phe-          nyl-3-methyl-5-pyrazolon    werden in 150 Tei  len Wasser mit 20 Teilen     calcinierter    Soda  gelöst, mit Eis gekühlt und hierauf mit der       Diazoverbindung    aus 23 Teilen     4-Acetamino-          2-amino-l-benzolsulfosäure    versetzt. Der sich  bildende Farbstoff scheidet sich teilweise aus.    Durch Zusatz von Kochsalz     wird    die     Fällung     vervollständigt, 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 when diazotized dye is obtained when diazotized 4-acetamino-2-amino-1-benzenesulfonic acid is coupled with 1 pyrazolone. The dye obtained in this way forms a yellow powder. He dyes wool from a sulfuric acid bath in a very great deal. even, green-yellow tones. The dyeings are very resistant to light, water and alkali and withstand acidic fulling.



  <I> Example: </I> 39 parts of 1- (- 2'-chloro-4'-sulfonic acid) -phenyl-3-methyl-5-pyrazolone are dissolved in 150 parts of water with 20 parts of calcined soda, cooled with ice and then mixed with the diazo compound from 23 parts of 4-acetamino-2-amino-1-benzenesulfonic acid. The dye that forms is partially separated out. The precipitation is completed by adding sodium chloride, then it is made as neutral as possible, filtered and dried.

PATENT CLAIM: Process for the preparation of a new dye, characterized in that diazotized 4-acetamino-2-amino-1-benzene sulfonic acid with 1 - (- 2'-chloro-4'-sulfonic acid) - phenyl-3-methyl- 5-pyrazolone couples. 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 resistant to light, water and alkali and withstand acidic fulling.
