Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 178224.         Verfahren    zur Herstellung eines neuen     Farbstoffes.       Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man     diazotiertes        2-          Amino-5-acetylaminophenyläthylsulfon    in  saurem Medium mit der     2-Amino-8-oxynaph-          thalin-6-sulfonsäure    vereinigt. Der neue  Farbstoff bildet ein dunkles Pulver, das sich  in Wasser mit blauroter Farbe löst. Es färbt  Wolle aus saurem Bade in echten blaustichig  roten Farbtönen an.  



  <I>Beispiel:</I>  242 Teile 2-     Amino-5-acetylaminophenyl-          äthy        lsulfon    werden unter Zugabe von Salz  säure und 69 Teilen     Natriumnitrit    in die       Diazoverbindung    übergeführt. In diese     Di-          azolösung    trägt man eine neutrale Lösung  von 239 Teilen 2-Amino-8-oxynaphthalin-6-         sulfonsäure    ein und beschleunigt die Reak  tion durch Zugabe von     Natriumacetat.    Der  Farbstoff wird nun     abfiltriert,    ausgewaschen  und getrocknet.



  <B> Additional patent </B> to main patent no. 178224. Process for the production of a new dye. It has been found that a new dye is obtained if diazotized 2-amino-5-acetylaminophenylethylsulfone is combined with 2-amino-8-oxynaphthalene-6-sulfonic acid in an acidic medium. The new dye forms a dark powder that dissolves in water with a blue-red color. It stains wool from an acid bath in real blue-tinged red shades.



  <I> Example: </I> 242 parts of 2-amino-5-acetylaminophenyl ethy lsulfon are converted into the diazo compound with the addition of hydrochloric acid and 69 parts of sodium nitrite. A neutral solution of 239 parts of 2-amino-8-oxynaphthalene-6-sulfonic acid is introduced into this diazo solution and the reaction is accelerated by adding sodium acetate. The dye is then filtered off, washed out and dried.
