Description

  

  Verfahren zur Herstellung einer     quaternären        Ammoniumverbindung.       Gegenstand des Hauptpatentes ist ein  Verfahren zur Herstellung einer     quaternären          Ammoniumverbindung    durch Einwirkenlassen  von     Benzylchlorid    auf     Diäthyldodecylamin.     



  Gegenstand des vorliegenden Patentes ist  ein Verfahren zur Herstellung einer ähnlichen       quaternären        Ammoniumverbindung.    Das Ver  fahren ist dadurch gekennzeichnet, dass man  auf     Dimethyloktadecylamin        Benzylbromid    ein  wirken lässt. Die Reaktion erfolgt zweckmässig  unter Erwärmen und kann in Gegenwart eines       Verdünnemittels,    wie Wasser oder Alkohol,       durchgeführtwerden.    Durch     Umkristallisieren     aus Benzol lässt sich das bei der Reaktion  entstandene     Dimethyl-oktadecyl-benzylammo-          niumbromid    gewinnen.

   Man erhält ein farb  loses Kristallmehl, das bei Erwärmen bei etwa  70   sintert, ohne einen scharfen Schmelzpunkt  zu zeigen. Es löst sich klar in warmem Wasser  zu einer stark schäumenden Lösung und hat  netzende und     desinfizierende    Eigenschaften.    Es soll vornehmlich für Desinfektionszwecke  Anwendung finden.  



  <I>Beispiel:</I>  297 Gewichtsteile     Dimethyl-oktadecyl-          amin    erwärmt man mit 171 Gewichtsteilen       Benzylbromid    12 Stunden unter Rühren auf  100  . Nach dem Erkalten löst man das  Reaktionsprodukt aus 4 Gewichtsteilen sie  dendem Benzol um und erhält so das     Dime-          thyl-oktadecyl-benzylammoniumbromid    als  farbloses Kristallmehl. Die Substanz beginnt  bei etwa 70   zu sintern, ohne einen scharfen  Schmelzpunkt zu zeigen. Sie löst sich klar  in warmem Wasser zu einer stark schäumen  den Lösung.



  Process for the preparation of a quaternary ammonium compound. The main patent relates to a process for the preparation of a quaternary ammonium compound by allowing benzyl chloride to act on diethyldodecylamine.



  The present patent relates to a process for the preparation of a similar quaternary ammonium compound. The process is characterized in that dimethyloctadecylamine benzyl bromide is allowed to act. The reaction is conveniently carried out with heating and can be carried out in the presence of a diluent, such as water or alcohol. The dimethyl-octadecyl-benzylammonium bromide formed in the reaction can be obtained by recrystallization from benzene.

   A colorless crystal flour is obtained which sinters at about 70 when heated without showing a sharp melting point. It dissolves clearly in warm water to form a strong foaming solution and has wetting and disinfecting properties. It should primarily be used for disinfection purposes.



  <I> Example: </I> 297 parts by weight of dimethyl-octadecylamine are heated with 171 parts by weight of benzyl bromide to 100 for 12 hours while stirring. After cooling, the reaction product is redissolved from 4 parts by weight of benzene and thus the dimethyl octadecyl benzylammonium bromide is obtained as colorless crystal flour. The substance begins to sinter at around 70 without showing a sharp melting point. It dissolves clearly in warm water to form a strongly foaming solution.
