Description

  

  Verfahren zur Darstellung eines     quaternären        Aminoessigsäureamidderisates.       Es wurde gefunden, dass man durch     Um-          setzungvon        Chloracetyl-N-cetylarnilid,        herstell-          bar    aus     N-Cetylanilin    und     Chloracetylchlorid,

       mit     Dimethylamin    zum     Dimethylaminoessig-          säure-N-cetylanilid    und durch Behandlung des  letzteren mit     p-Toluolsulfornsäure-n-amylester     zu der entsprechenden     quaternären    Ammonium  verbindung gelangen kann. Die neue Verbin  dung, in festem Zustand eine salben- bis wachs  artige Masse von heller Farbe, löst sich sehr  leicht in Wasser und weist stark ausgeprägte       kapillaraktive    Eigenschaften auf.

   Sie soll  Verwendung finden als     Weichmachungsmittel,     Abziehmittel für     Naphthol-AS-    und     Küpen-          färbungen    und als Mittel zum Verbessern der  Wasserechtheit vorn direkt gefärbter nativer  und umgefällter Zellulose.  



  <I>Beispiel:</I>  Zu 600 g wässriger     Dimethylaminlösung     von 20,4  % werden 300 g     Chloracetyl        -N-          cetylanilid,    hergestellt aus     N-Cetylanilin    und       Chloracetylchlorid,        zutropfen    gelassen. An-         fänglich    erwärmt sich das Reaktionsgemisch  kaum, erst wenn alles zugegeben ist, tritt  eine Temperaturerhöhung auf 40-45   ein.  Das Reaktionsgemisch wird im Laufe von  3-4 Stunden auf 80-90   erwärmt und wei  tere 20 Stunden bei dieser Temperatur ge  rührt.

   Das Endprodukt reagiert noch     phenol-          phthaleirnalkalisch    und soll in Säuren klar  löslich sein. Man giesst in 500     em3    Wasser  und trennt das abgeschiedene 01 ab. Hierauf  gibt man zum     Dimethylamirnoessigsäure-N-          cetylanilid    1 Liter Wasser und stellt mit  Salzsäure kongosauer. Die stark schäumende  Lösung wird mit Äther von geringen Mengen  an Nebenprodukten befreit, die     wässrige    Lö  sung mit Soda     älkaliseh    gestellt, das End  produkt von der     wässrigen    Schicht abgetrennt,  getrocknet und im Vakuum destilliert.  



  40,2 g     Dimethylamirnoessigsäure-N-cetyl-          anilid    werden mit 24,2 g     p-Toluolsulfonsäure-          n-amylester    zusammengegeben und 6 Stunden  bei 120-130   gerührt. Das Produkt ist dann  vollständig und klar wasserlöslich. Man er-      hält die neue Verbindung als salben- bis  wachsartige blasse, die sich sehr leicht in  Wasser löst und stark ausgeprägte kapillar  aktive Eigenschaften aufweist.

   Die neue Ver  bindung soll     Verwendung    finden als     Weich-          rnachungsmittel,    Abziehmittel für     Naphthol-          AS-    und     Küpenfärbungen    und als Mittel zum  Verbessern der Wasserechtheit von direkt ge  färbter nativer und umgefüllter     Zellulose.  



  Process for the preparation of a quaternary Aminoessigsäureamidderisates. It has been found that by reacting chloroacetyl-N-cetylarnilide, which can be prepared from N-cetylaniline and chloroacetyl chloride,

       with dimethylamine to dimethylaminoacetic acid-N-cetylanilide and treatment of the latter with p-toluenesulfuric acid-n-amyl ester to the corresponding quaternary ammonium compound. The new compound, in its solid state an ointment-like to waxy mass of light color, dissolves very easily in water and has very pronounced capillary-active properties.

   It is said to be used as a plasticizer, a stripping agent for naphthol AS and vat dyeings and as an agent for improving the water fastness of directly dyed native and reprecipitated cellulose.



  <I> Example: </I> 300 g of chloroacetyl-N-cetylanilide, prepared from N-cetylaniline and chloroacetyl chloride, are added dropwise to 600 g of aqueous dimethylamine solution of 20.4%. Initially the reaction mixture hardly warms up, only when everything has been added does the temperature increase to 40-45. The reaction mixture is heated to 80-90 in the course of 3-4 hours and stirred at this temperature for another 20 hours.

   The end product still reacts in a phenol-phthalene-alkaline manner and should be clearly soluble in acids. It is poured into 500 cubic meters of water and the separated oil is separated off. Then 1 liter of water is added to the dimethylaminoacetic acid-N-cetylanilide and acidified to Congo with hydrochloric acid. The strongly foaming solution is freed from small amounts of by-products with ether, the aqueous solution is made alkaline with soda, the end product is separated from the aqueous layer, dried and distilled in vacuo.



  40.2 g of dimethylaminoacetic acid-N-cetyl-anilide are combined with 24.2 g of p-toluenesulfonic acid-n-amyl ester and stirred for 6 hours at 120-130. The product is then completely and clearly soluble in water. The new compound is obtained as an ointment-like to waxy pale, which dissolves very easily in water and has strongly pronounced capillary-active properties.

   The new compound is intended to be used as a softening agent, a stripping agent for naphthol, AS and vat dyeing and as a means to improve the waterfastness of directly dyed native and decanted cellulose.
