Description

  

  Verfahren zur Herstellung einer     wasserlösliehen        Diazoamidoverbindung.       Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung einer wasser  löslichen     Diazoamidoverbindnng.    Es ist da  durch gekennzeichnet, dass man     Piperidin-          3-sialfonsäure    auf     diazotiertes        1-Amino-4-(4'-          metliyl        -phenoxyacetylamino)    - 2,5-     dimethoxy-          benzol    in Gegenwart eines säurebindenden  Mittels einwirken lässt.  



  <I>Beispiel:</I>  In eine wässerige Lösung von     1"7        gr        pipe-          ridin-3-sulfonsaurem        Natrium    und 20     gi-    Soda  lässt man bei<B>150</B> eine     Diazolösung    aus 23     gr     1-     Amino-    4 - (4' -     methylphenoxyacetylamino)-          2,5-dimethogybenzol    langsam zufliessen. Die       Reaktion    ist schnell beendet. Aus der Lösung  wird die gelblich gefärbte Diazoamidoverbin-    Jung bei 40   durch Zusatz von Kochsalz  ausgefällt.

   Sie ist in Wasser löslich und ist  ein wertvolles Produkt für     Färbereizwecke.  



  Process for producing a water-soluble diazoamido compound. The subject of the present patent is a process for the preparation of a water-soluble diazoamido compound. It is characterized in that piperidine-3-sialfonic acid is allowed to act on diazotized 1-amino-4- (4'-methylphenoxyacetylamino) -2,5-dimethoxybenzene in the presence of an acid-binding agent.



  <I> Example: </I> A diazo solution of 23 g 1-amino is added at <B> 150 </B> to an aqueous solution of 1 "7 gr. Of piperidine-3-sulfonic acid sodium and 20 g - 4 - (4 '- methylphenoxyacetylamino) - 2,5-dimethogybenzene slowly pour in. The reaction is quickly over. The yellowish colored diazoamido compound is precipitated from the solution by adding sodium chloride.

   It is soluble in water and is a valuable product for dyeing purposes.
