Description

  

  Verfahren zur Verstellung eines neuen     quaternären        Ammoniumsalzes.       Vorliegende Erfindung bezieht sich auf  ein Verfahren zur Herstellung eines neuen       quaternären        Ammoniumsalzes.     



  Gemäss der Erfindung wird ein neues     qua-          ternäres        Ammoniumsalz,    geeignet zu Textil  behandlungsverfahren, erhalten, indem man       Octadecyloxymethyl-pyridinpyridinsulfit    und  wasserfreie     Oxalsäure    in Gegenwart von     Py-          ridin    miteinander reagieren lässt.  



       Beispiel:     27 Teile     Octadecylalkohol,    64 Teile     Py-          ridin    und 8 Teile     Paraformaldehyd    werden  zusammen bei<B>800</B> C gerührt und dann wird  Schwefeldioxyd in solchem Betrag dem Ge  misch zugesetzt, dass die Temperatur bei 84  bis<B>88"</B> C verbleibt, bis eine entnommene  Probe des     Reaktionsgemisches    sich in kaltem       Wasser    vollständig löst.  



  Der so erhaltenen heissen Lösung des     Oc-          tadecyloxymethylpyridinpyridinsulfits    in     Py-          ridin    werden 10 Teile wasserfreie     O$alsäure       zugesetzt und das Gemisch wird bei 85 bis  <B>900</B> C so lange gerührt, bis sich eine gleich  mässige klare Flüssigkeit gebildet hat. Nach  langsamem, mehrstündigem Abkühlen auf  20   C scheidet sich ein weisser, kristallinischer  Körper ab. Dieser wird     abfiltriert    und aus       Methylalkohol    wieder auskristallisiert.

   Das  so erhaltene neue,     quaternäre        Ammoniumsalz,     saures     Octadecyloxymethyl-pyridinoxa.lat,    ist  eine weisse, kristallene Substanz mit einem  Schmelzpunkt von 117 bis<B>1180</B> C. Das Salz  löst sich in warmem Wasser, ergibt eine klare       schäumende    Lösung, welche auf Kongorot  papier stark sauer reagiert und welche sich  beim lochen trübt.



  Process for adjusting a new quaternary ammonium salt. The present invention relates to a process for the preparation of a new quaternary ammonium salt.



  According to the invention, a new quaternary ammonium salt, suitable for textile treatment processes, is obtained by allowing octadecyloxymethylpyridine pyridine sulfite and anhydrous oxalic acid to react with one another in the presence of pyridine.



       Example: 27 parts of octadecyl alcohol, 64 parts of pyridine and 8 parts of paraformaldehyde are stirred together at <B> 800 </B> C and then sulfur dioxide is added to the mixture in such an amount that the temperature is 84 to 88 "C remains until a sample of the reaction mixture taken dissolves completely in cold water.



  10 parts of anhydrous acid are added to the hot solution of octadecyloxymethylpyridine pyridine sulfite in pyridine, and the mixture is stirred at 85 to 900 C until a uniform, clear liquid has formed . After slowly cooling to 20 ° C. for several hours, a white, crystalline body separates out. This is filtered off and crystallized out again from methyl alcohol.

   The new, quaternary ammonium salt obtained in this way, acidic octadecyloxymethylpyridinoxa.late, is a white, crystalline substance with a melting point of 117 to 1180 C. The salt dissolves in warm water, giving a clear, foaming solution which reacts strongly to Congo red paper and which becomes cloudy when punched.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen quaternären Ammoniumsalzes; für Textilbe- handlungsverfahren geeignet, dadurch gekenn zeichnet, dass man Octadecyloxymethyl-pyri- dinpyridinsulfit und wasserfreie Oxalsäure in Gegenwart von Pyridin miteinander reagieren lässt. Das neue quaternäreAmmoniumsalz, saures Octadecyloxymethylpyridinoxalat, ist eine weisse, kristallene Substanz mit einem Schmelz punkt von 117 bis 118 0. PATENT CLAIM: Process for the production of a new quaternary ammonium salt; suitable for textile treatment processes, characterized in that octadecyloxymethylpyridine pyridine sulfite and anhydrous oxalic acid are allowed to react with one another in the presence of pyridine. The new quaternary ammonium salt, acid octadecyloxymethylpyridine oxalate, is a white, crystalline substance with a melting point of 117 to 118 0. Das Salz löst sich in warmem Wasser, ergibt eine klare schäumende Lösung, welche auf Kongorot papier stark sauer reagiert und welche sich beim Kochen trübt. The salt dissolves in warm water, resulting in a clear foaming solution which reacts strongly acidic to Congo red paper and which becomes cloudy when boiled.
