Description

  

      Zusatzpatent    zum Hauptpatent Nr. 163539.    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man dianotiertes       4-Methoxy-l-aminobenzol    mit     [p-(Phenyl-          äthyl)-aminoläthylmethy        läther    vereinigt.  



  Der neue Farbstoff bildet ein gelbes Pulver,  das in Wasser     unlöslich    ist, sich dagegen in  Essigester leicht mit gelber Farbe löst. Er  färbt     Acetatseide    in gelben Tönen.  



       Beispiel:     12,3 Teile     4-Methoxy-l-amittobenzol    wer  den mit Wasser, 25 Teilen konzentrierter  Salzsäure und 7 Teilen     Natriumnitrit    unter  Zusatz von Eis dianotiert. Die erhaltene     Di-          azolösung    lässt man zu einer Lösung von  17,9 Teilen [i3-(Phenyl-äthyl)-amino]äthyl-         methyläther    in verdünnter Salzsäure zufliessen.  Dann versetzt man langsam mit Natrium  acetatlösung bis die     .Kupplung    beendet ist.       DerFarbstoff    scheidet sich als gelbes 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 if dianotated 4-methoxy-1-aminobenzene is combined with [p- (phenyl-ethyl) -aminolethylmethy ether.



  The new dye forms a yellow powder that is insoluble in water, but easily dissolves with a yellow color in ethyl acetate. He dyes acetate silk in yellow tones.



       Example: 12.3 parts of 4-methoxy-l-amittobenzene who dianotized with water, 25 parts of concentrated hydrochloric acid and 7 parts of sodium nitrite with the addition of ice. The diazo solution obtained is allowed to flow into a solution of 17.9 parts of [i3- (phenylethyl) amino] ethyl methyl ether in dilute hydrochloric acid. Sodium acetate solution is then slowly added until the coupling has ended. The dye separates out as a yellow powder.
