Description

  

  Verfahren zur Herstellung eines neuen Kondensationsproduktes.    Es wurde gefunden, dass man zu einem  neuen Kondensationsprodukt gelangt, wenn  man     Acetanilid    mit     a,a'-Dichlordimethyl-          äther    reagieren lässt und das erhaltene Re  aktionsprodukt darauf mit     Pyridin    umsetzt.  



  Das auf diese Weise erhaltene neue Re  aktionsprodukt stellt ein gelbliches, hygro  skopisches Pulver dar, das in Wasser klar  und leicht löslich ist. Beim Erhitzen der  wässerigen Lösung des Produktes mit ver  dünnten     Alkalien    scheidet sich ein schwer  lösliches Zersetzungsprodukt ab. Das neue  Kondensationsprodukt kann als     Textilhilfs-          stoff,    z. B. zur Erhöhung der Affinität von  Fasern gegenüber sauren Farbstoffen, ver  wendet werden.  



       Beispiel:     135 Gewichtsteile     Acetanilid    werden mit  345 Gewichtsteilen     a,a'-Dichlordimethyläther     unter Rühren auf 100 bis 105   erhitzt, wo  bei das     Acetanilid    bald in Lösung geht und  nach kurzer Zeit eine Reaktion unter Salz  säureabspaltung einsetzt. Nach etwa 20 Stun-    den Reaktionsdauer ist die Umsetzung nahe  zu beendet. Hierauf wird der überschüssige  Äther im Vakuum     abdestilliert,    wobei das  neue Produkt als ein gelbliches Pulver zu  rückbleibt.  



  21 Gewichtsteile des so     erhaltenen    Umset  zungsproduktes aus     Acetanilid    und     a,ä        -Di-          chlordimethyläther    werden allmählich unter  Rühren bei etwa<B>100'</B> in 40 Gewichtsteile       Pyridin    eingetragen. Es entsteht ein zähes  Reaktionsgemisch, das ziemlich schwer zu  rühren ist. Man hält das     Reaktionsprodukt     so lange bei<B>100',</B> bis eine Probe in Wasser  klar löslich ist. Hierauf wird die gesamte  Reaktionsmasse im Vakuum zur Trockne  eingedampft.  



  Das auf diese Weise erhaltene neue Re  aktionsprodukt stellt ein gelbliches, hygro  skopisches. Pulver dar, das in Wasser klar  und leicht löslich ist. Beim Erhitzen der  wässerigen Lösung des Produktes mit ver  dünnten Alkalien scheidet sich ein schwer  lösliches Zersetzungsprodukt ab.



  Process for the production of a new condensation product. It has been found that a new condensation product is obtained if acetanilide is allowed to react with α, α'-dichlorodimethyl ether and the reaction product obtained is then reacted with pyridine.



  The new reaction product obtained in this way is a yellowish, hygroscopic powder that is clear and easily soluble in water. When the aqueous solution of the product is heated with dilute alkalis, a poorly soluble decomposition product is deposited. The new condensation product can be used as a textile auxiliary such. B. to increase the affinity of fibers to acidic dyes, ver used.



       Example: 135 parts by weight of acetanilide are heated with 345 parts by weight of a, a'-dichlorodimethyl ether with stirring to 100 to 105, where the acetanilide soon dissolves and after a short time a reaction starts with the elimination of hydrochloric acid. After about 20 hours of reaction time, the reaction is almost complete. The excess ether is then distilled off in vacuo, the new product remaining as a yellowish powder.



  21 parts by weight of the resulting reaction product of acetanilide and α, α-dichlorodimethyl ether are gradually introduced into 40 parts by weight of pyridine at about 100 parts by weight. A viscous reaction mixture results which is quite difficult to stir. The reaction product is kept at <B> 100 '</B> until a sample is clearly soluble in water. The entire reaction mass is then evaporated to dryness in vacuo.



  The new reaction product obtained in this way is yellowish, hygroscopic. Powder that is clear and easily soluble in water. When the aqueous solution of the product is heated with dilute alkalis, a poorly soluble decomposition product is deposited.
