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.
