Description

  

      Verfahren        zur        Herstellung    eines neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man     diazotierte    4  Acetamino-2-amino-l-benzolsulfosäure mit 1  (2'-methyl-4'-sulfosä:ure)-phenyl-5-pyrazolon  3-carbonsäure kuppelt. Der so erhalten 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.            Beispiel:       <B>29,8</B> Teile 1-     (2'-Methyl-4'-sulf        osäure)-          phenyl-5-pyrazolon-3-carbonsäure    werden in  150 Teilen Wasser mit 2,0 Teilen     calcinier-          ter    Soda gelöst, mit Eis gekühlt und hierauf  mit der     Diazoverbindung    aus 23 Teilen     4-          Acetamino-2-amino-l-benzolsulfosäure    ver  setzt. Der sich bildende Farbstoff scheidet    sich teilweise aus.

   Durch Zusatz von Koch  salz 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 4-acetamino-2-amino-1-benzenesulfonic acid is coupled with 1 (2'-methyl-4'-sulfoic acid) -phenyl-5-pyrazolone 3-carboxylic acid. The dye obtained in this way forms a yellow powder. He dyes wool from sulfuric acid bath in very even, green-yellow tones.

   The dyeings are very light, water and alkali fast. Example: 29.8 parts of 1- (2'-methyl-4'-sulfonic acid) phenyl-5-pyrazolone-3-carboxylic acid are calcined in 150 parts of water with 2.0 parts Soda dissolved, cooled with ice and then ver 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 production of a new dye, characterized in that diazotized 4-acetamino-2-amino-1-benzene sulfonic acid with 1- (2'-methyl-4'-sulfonic acid) - phenyl-5-pyrazolone-3 -carboxylic acid couples. The dye thus obtained forms a yellow powder. He dyes wool from sulfuric acid bath in very even, green-yellow tones. The colors are very light, water and alkali fast.
