Description

  

  Zusatzpatent zum Hauptpatent Nr. 163539.    Verfahren zur Herstellung eines neuen     Azofarbstoftes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man dianotiertes       4-Nitro-2-niethoxy-l-aminobeiizol    mit     (P-(Phe-          nyl-äthyl)-aminojäthylmethyläther    vereinigt.  



  Der neue     Farbstoff    bildet ein violett  braunes Pulver, das in Wasser unlöslich ist,  sich dagegen in Essigester leicht mit roter  Farbe löst. Er färbt     Acetatseide    in roten  Tönen.  



       Beispiel:     16,8 Teile     4-Nitro-2-methoxy-l-aminoben-          zol    werden mit Wasser vermahlen und mit  25 Teilen konzentrierter Salzsäure und 7  Teilen     Natriumnitrit    unter Zusatz von Eis  dianotiert. Die erhaltene     Diazolösung    lässt       irian    zu einer Lösung von 17,9 Teilen       (Phenyl-äthyl)-aminol        äthylmethyläther    in ver  dünnter     Salzsäure    zufliessen. Dann versetzt    man langsam mit     Natriumacetatlösung,    bis  die Kupplung beendet ist.

   Der     Farbstoff     scheidet sich als     violettbraunes    Pulver aus.



  Additional patent to main patent No. 163539. Process for the production of a new azo dye. It has been found that a new azo dye is obtained when dianotated 4-nitro-2-niethoxy-1-aminobeiizole is combined with (P- (phenyl-ethyl) -aminojethylmethyl ether.



  The new dye forms a purple-brown powder that is insoluble in water, but easily dissolves red in ethyl acetate. He dyes acetate silk in red tones.



       Example: 16.8 parts of 4-nitro-2-methoxy-1-aminobenzene are ground with water and dianotized with 25 parts of concentrated hydrochloric acid and 7 parts of sodium nitrite with the addition of ice. The resulting diazo solution can flow irian to a solution of 17.9 parts of (phenyl-ethyl) -aminol ethylmethyl ether in dilute hydrochloric acid. Sodium acetate solution is then slowly added until the coupling has ended.

   The dye separates out as a purple-brown powder.
