Description

  

  Verfahren zur Herstellung eines neuen Kondensationsproduktes.    Es wurde gefunden,     dass    man ein neues  Kondensationsprodukt erhält, wenn man     p-          Chlorphenylsulfonacetonitril    mit     (N-Äthyl-          N-oxäthyl)-p-aminobenzaldehyd    kondensiert.  



  Das neue Kondensationsprodukt ist ein  gelbes Pulver, das in Wasser     unlöslich    ist,  sich dagegen in Essigester leicht mit grün  gelber Farbe löst und, in geeignete feine  Verteilung gebracht,     Acetatkunstseide    in       grünstichig    gelben Tönen färbt.

           Beispiel:       21,5     Gewichtsteile        p-Chlorphenylsulfon-          acetonitril    werden zusammen mit<B>19,3</B> Ge  wichtsteilen     (N-Äthyl-N-oxäthyl)p-amino-          benzaldehyd    in Alkohol gelöst und unter  Zusatz von einigen Tropfen     Piperidin    einige  Zeit unter     Rückfluss    gekocht.     iSchon    nach  kurzem Kochen tritt     intensive    Gelbfärbung  der Flüssigkeit durch     dae    sich bildende Kon  densationsprodukt ein.

   Man kocht solange,    bis die Farbintensität nicht mehr zunimmt,  was den Endpunkt der     Reaktion    anzeigt.  Darauf lädt man unter Rühren erkalten,  wobei sich das     Kondensationsprodukt    als  gelbes Pulver ausscheidet.



  Process for the production of a new condensation product. It has been found that a new condensation product is obtained when p-chlorophenylsulfonacetonitrile is condensed with (N-ethyl-N-oxethyl) -p-aminobenzaldehyde.



  The new condensation product is a yellow powder that is insoluble in water, but easily dissolves in ethyl acetate with a green-yellow color and, when appropriately finely divided, dyes acetate rayon in greenish yellow tones.

           Example: 21.5 parts by weight of p-chlorophenylsulfonic acetonitrile are dissolved in alcohol together with 19.3 parts by weight of (N-ethyl-N-oxethyl) p-aminobenzaldehyde and a few drops of piperidine are added refluxed for some time. Even after a short boil, the liquid turns yellow due to the condensation product that forms.

   The mixture is boiled until the color intensity no longer increases, which indicates the end point of the reaction. The mixture is then cooled while stirring, the condensation product separating out as a yellow powder.
