Description

  

  Verfahren zur Herstellung eines neuen     quaternären        Ammoniumsalzes.       Gemäss der vorliegenden Erfindung ist ein  Verfahren zur Herstellung eines zum     Was-          serabstossendmachen    von Gewebe brauchbaren,  neuen,     quaternären        Ammoniumsalzes    dadurch  gekennzeichnet,     dass        Pyridin,    wasserfreie     Oxal-          säure    und     Stearohydroxymethylamicl    zusam  men zur Reaktion gebracht werden.  



  Wenn gewünscht, kann die Reaktion auch  in Gegenwart einer solchen Menge     Pyridin     ausgeführt werden,     dass    letzteres zugleich als  Verdünnungsmittel wirkt, so     dass    die     Reah-          tionsmasse    im flüssigen Zustande erhalten  bleibt. Anderseits können auch andere Ver  dünnungsmittel zum selben Zwecke verwen  det werden, wie Chloroform, Benzol oder       Toluol.     



  <I>Beispiel:</I>  <B>9</B> Teile fein pulverisierte wasserfreie       Oxalsäure    werden in<B>100</B> Teile     Pyridin    von  <B><I>60</I> 0</B> eingerührt. Hierauf werden<B>10</B> Teile       Stearobydroxymethylamid    zugesetzt und das    Ganze wird unter Umrühren während vier  Stunden auf<B>600 C</B> erhitzt. Die Temperatur  wird hierauf auf     70-8011   <B>0</B> erhöht     und    das  Umrühren während 12 Stunden bei dieser  Temperatur fortgesetzt.

   Das Reaktionsge  misch wird gekühlt, mit Aceton verdünnt  und der so entstandene weisse,     kristallinisehe     Niederschlag     abfiltriert.    Das auf diese Weise  erhaltene     Stearamidomethylpyridiniumoxalat     ist ein weisser, kristallinischer Körper, wel  cher in Methylalkohol oder Chloroform wenig  löslich ist. Der Salz, das sich in heissem  Wasser spärlich löst, gibt eine klare, schäu  mende Lösung. Es ist in heissem     Pyridin     löslich, aus welchem Lösungsmittel es leicht  kristallisiert werden kann.



  Process for the preparation of a new quaternary ammonium salt. According to the present invention, a method for producing a new, quaternary ammonium salt useful for making tissue water-repellent is characterized in that pyridine, anhydrous oxalic acid and stearohydroxymethylamyl are reacted together.



  If desired, the reaction can also be carried out in the presence of such an amount of pyridine that the latter also acts as a diluent, so that the reaction mass is retained in the liquid state. On the other hand, other diluents can be used for the same purpose, such as chloroform, benzene or toluene.



  <I> Example: </I> <B> 9 </B> parts of finely powdered anhydrous oxalic acid become <B> <I> 60 </I> 0 </ B in <B> 100 </B> parts of pyridine > stirred in. <B> 10 </B> parts of stearobydroxymethylamide are then added and the whole is heated to <B> 600 ° C. for four hours while stirring. The temperature is then increased to 70-8011 <B> 0 </B> and stirring is continued for 12 hours at this temperature.

   The reaction mixture is cooled, diluted with acetone and the resulting white, crystalline precipitate is filtered off. The stearamidomethylpyridinium oxalate obtained in this way is a white, crystalline body which is sparingly soluble in methyl alcohol or chloroform. The salt, which dissolves sparsely in hot water, gives a clear, foaming solution. It is soluble in hot pyridine, from which solvent it can be easily crystallized.
