Description

  

      Zusatzpatent    zum Hauptpatent Nr. 163539.    Verfahren zur Herstellung eines neuen     Azofarbstofes.       Es wurde     gefunden,    dass man einen neuen       Azofarbstoff    erhält, wenn man dianotiertes       2.4-Dinitranilin    mit     [@-(2-Methoxy-5-metlryl)-          phenylanrinoj        äthylrnethyläther    vereinigt.  



  Der neue     Farbstoff    bildet ein dunkles Pul  ver, das in Wasser unlöslich ist, sich dagegen  in Essigester leicht mit     violettroter    Farbe löst.  Er färbt     Acetatseide    in violetten Tönen.  



  <I>Beispiel:</I>  18,3 Teile     2.4-Dinitranilin    werden in eine  aus 50 Teilen Schwefelsäure 66   136 und 8  Teilen     Natriumnitrit    hergestellte Lösung von       Nitrosylschwefelsäure    eingerührt. Die Diano  tierung ist beendet, wenn eine Probe sich in  Eiswasser klar löst. Nun giesst man auf  Wasser und Eis. Die erhaltene     Diazolösung     lässt man zu einer Lösung von 19,5 Teilen         [@-(2-DZethoxy-    5 -     methyl)-phenylamirro]        ätbyl-          methyläther    in verdünnter Salzsäure zufliessen.  Dann versetzt man langsam mit Natrium  acetatlösung bis die Kupplung beendet ist.

    Der Farbstoff scheidet sieh als violettes Pul  ver 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 2,4-dinitraniline is combined with [@ - (2-methoxy-5-methyl) phenylanrino] ethyl methyl ether.



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



  <I> Example: </I> 18.3 parts of 2,4-dinitraniline are stirred into a solution of nitrosylsulfuric acid prepared from 50 parts of sulfuric acid 66 136 and 8 parts of sodium nitrite. The dialing is finished when a sample dissolves clearly in ice water. Now you pour on water and ice. The diazo solution obtained is allowed to flow into a solution of 19.5 parts of [@ - (2-Dzethoxy-5-methyl) -phenylamirro] ethyl-methyl ether in dilute hydrochloric acid. Sodium acetate solution is then added slowly until the coupling has ended.

    The dye separates out as a violet powder.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Azofarbstoffes, dadurch gekennzeichnet, dass man dianotiertes 2.4-Dinitranilin mit [P-(2 Methoxy-5-methyl)-plrenylamino]äthylmethyl- äther vereinigt. Der neue Farbstoff bildet ein dunkles Pul ver, das in Wasser unlöslich ist, sich dagegen in Essigester leicht mit rotvioletter Farbe löst. Er färbt Acetatseide in violetten Tönen. PATENT CLAIM: A process for the production of a new azo dye, characterized in that dianotated 2,4-dinitraniline is combined with [P- (2 methoxy-5-methyl) -plrenylamino] ethyl methyl ether. The new dye forms a dark powder that is insoluble in water, but easily dissolves in ethyl acetate with a red-violet color. He dyes acetate silk in purple tones.
