  Verfahren zur Darstellung eines     quaternären        Aminoessigsäureamidderivates.       Es wurde gefunden,     dass    man durch Um  setzung von     Chloracetyl-N-methylamid,    her  stellbar aus     Methylamin    und     Chloracetyl-          chlorid,    mit     Dimethylamin    zum     Dimethyl-          aminoessigsäure-N-methylamid    und durch  Behandlung des letzteren mit     Lorylbromid          (unter        "Lcryl"        wird,das        Alkylradikal,

      wel  ches dem aus     gokosöl    gewonnenen Gemisch  der     höhermolekularen    Alkohole entspricht,  verstanden) zu der entsprechenden     quater-          nären        Ammoniumverbindung    gelangen kann.

    Die neue Verbindung, in festem Zustand eine       salben-    bis wachsartige Masse von heller  Farbe, löst sieh sehr leicht in Wasser und       weist    stark     ausgeprägte,        kapillaraktive    Eigen  schaften auf. !Sie soll Verwendung finden  als     Weichmachungsmittel,        Abziehmittel    für       Naphthol-AS-    und     güpenfärbungen    und     aJs     Mittel zum     Verbessern    der Wasserechtheit  von direkt gefärbter nativer     und,    umgefällter  Zellulose.  



  <I>Beispiel:</I>  Zu 600g wässriger     Dimethylaminlösung     von 20,4 % werden 300     g    Chloracetyl-N-         methylamid,    hergestellt aus     Methylamin    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-          phthaleinalkalisch    und soll in Säuren klar  löslich sein. Man giesst in 500 cm' Wasser  und trennt das abgeschiedene 01 ab. Hierauf  gibt man zum     Dimethylaminoessigsäure-N-          methylamid    1     Liter    Wasser und     stellt    mit  Salzsäure kongosauer.

   Die stark     schäumende     Lösung wird mit Äther von geringen Mengen  an Nebenprodukten     befreit,    die     wässrige     Lösung mit Soda alkalisch     gestellt,    das  Endprodukt von der     wässrigen        ;Schicht    ab  getrennt, getrocknet und im Vakuum destil  liert.  



  <B>11,6</B> g     Dimethylaminoessigsäure-N-me-          thylamid    werden mit 24,9     ,g        Lorylbromi.d     zusammengegeben und 3-4 Stunden unter           Rühren    auf     130-140      C erwärmt.     Das    Pro  dukt ist dann vollständig und klar wasser  löslich. Man erhält die neue Verbindung als  salben- bis wachsartige Masse, die sich sehr  leicht in Wasser löst und stark ausgeprägte.

         kapillaraktive        Eigenschaften    aufweist.     Die     neue Verbindung soll Verwendung finden  als     Weichmachungsmittel,        Abziehmittel    für       Naphthol-AS-    und     Küpenfärbungen    und als  Mittel zum Verbessern der Wasserechtheit  von direkt gefärbter nativer und umgefällter       Zellulose.  



  Process for the preparation of a quaternary aminoacetic acid amide derivative. It has been found that by reacting chloroacetyl-N-methylamide, which can be produced from methylamine and chloroacetyl chloride, with dimethylamine to dimethylaminoacetic acid-N-methylamide and by treating the latter with loryl bromide (under "Lcryl", the Alkyl radical,

      which corresponds to the mixture of higher molecular weight alcohols obtained from goos oil, understood) can lead to the corresponding quaternary ammonium compound.

    The new compound, in the solid state an ointment-like to waxy mass of light color, dissolves very easily in water and has strong, capillary-active properties. It is said to be used as a plasticizer, a stripping agent for naphthol AS and güpen dyeings and as an agent for improving the waterfastness of directly dyed native and reprecipitated cellulose.



  <I> Example: </I> 300 g of chloroacetyl-N-methylamide, prepared from methylamine 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 rise to 40-45 '. The reaction mixture is heated to 80-90 in the course of 3-4 hours and stirred for a further 20 hours at this temperature.

   The end product still reacts in an alkaline phenolphthalein and should be clearly soluble in acids. It is poured into 500 cm 'of water and the separated oil is separated off. Then 1 liter of water is added to the N-methylamide dimethylaminoacetic acid and acidified to Congo with hydrochloric acid.

   Small amounts of by-products are removed from the foaming solution with ether, the aqueous solution is made alkaline with soda, the end product is separated from the aqueous layer, dried and distilled in vacuo.



  11.6 g of dimethylaminoacetic acid N-methylamide are combined with 24.9 g of loryl bromide and heated to 130-140 ° C. for 3-4 hours while stirring. The product is then completely and clearly soluble in water. The new compound is obtained as an ointment-like to waxy mass, which dissolves very easily in water and is very pronounced.

         Has capillary-active properties. The new compound is said to be used as a plasticizer, a stripping agent for naphthol-AS and vat dyeings and as an agent for improving the waterfastness of directly dyed native and reprecipitated cellulose.
