Description

  

      Verfahren    zur Herstellung einer wasserlöslichen     Diazoa.midoverbindung.            (-r'egeiiytand    des vorliegenden Patentes ist  ein Verfahren zur Herstellung einer wasser  löslichen     Diazoainidoverbindung.    Es ist da  durch gekennzeichnet. dass man     Piperidin-3-          sulfonsäure    auf     diazotiertes        1-Ainino-2-me-          thy1-5-chlorberizol    in Gegenwart eines säure  bindenden Mittels einwirken lässt.  



  <I>Beispiel.:</I>  In eine wässerige Lösung von 17     gi-        piperi-          dir)-3-siilfonsaureiri    Natrium und 20     gr    Soda  lässt man bei 15   eine     Diazolösung    aus 10,3     gr          1-Amirio-2-methyl-5-chlor-benzol        langsam    zu  fliessen. Die     Reaktion    ist schnell beendet.  Aus der Lösung wird die farblose kristalline       Diazoamidoverbindung    durch Zusatz von    Kochsalz ausgefällt.

   Sie ist in Wasser löslich  und ist     ein    wertvolles Produkt für     Färberei-          zwecke.  



      Process for the preparation of a water-soluble diazoa.mido compound. (-r'egeiiytand of the present patent is a process for the preparation of a water-soluble diazoainido compound. It is characterized by that piperidine-3-sulfonic acid on diazotized 1-amino-2-methy1-5-chlorberizole in the presence of an acid binding agent can act.



  <I> Example .: </I> In an aqueous solution of 17 gi- piperi- dir) -3-siilfonsaureiri sodium and 20 g soda, a diazo solution of 10.3 g 1-Amirio-2-methyl- 5-chloro-benzene to flow slowly. The reaction ends quickly. The colorless crystalline diazoamido compound is precipitated from the solution by adding sodium chloride.

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