Description

Verfahren zur Herstellung hochmolekularer N-Alkylpyridiniumhalogenide Hochmolekulare N-Alkylpyridiniumhalogenide wurden bisher durch Umsetzung von Alkylhalogeniden mit Pyridinbasen erhalten. Für ihre Herstellung muß man aber auf die durch Hochdruckhydrierung der entsprechenden Fettsäuren erhältlichen Alkohole und die daraus hergestellten Alkyl.halogenide zurückgreifen.Process for the preparation of high molecular weight N-alkylpyridinium halides High molecular weight N-alkylpyridinium halides were previously obtained by reacting alkyl halides obtained with pyridine bases. For their production, however, one has to resort to high-pressure hydrogenation of the corresponding fatty acids obtainable and the alcohols produced therefrom Use alkyl halides.

Wie nun gefunden wurde, lassen sich derartige Pyridiniumverbindungen aus höheren Fettsäuren in der Weise gewinnen, daß man aus diesen erhältliche a-Halogenfettsäuren mit den Pyridinbasen erhitzt. Die Umsetzung verläuft je nach Art der Ausgangsstoffe entweder lebhaft unter Selbsterwärmung oder erfordert, insbesondere bei Verwendung der Chlorverbindungen, längeres Erwärmen. Es entsteht dabei jeweils unter Kohlensäureabspa1tung das uni ein Kohlenstoffatom ärtnere quaternäre N-Alkylpyri-diniumhalogenid.As has now been found, such pyridinium compounds win from higher fatty acids in such a way that one can obtain α-halogen fatty acids from them heated with the pyridine bases. The implementation takes place depending on the type of starting materials either briskly self-heating or required, especially when in use the chlorine compounds, prolonged heating. In each case, it is produced with carbon dioxide being removed the quaternary N-alkylpyridinium halide, one carbon atom apart.

Für das Verfahren eignen sich die a-Halogenabkömmlinge gesättigter hochmolekularer Fettsäuren, wie der Laurin-, Palmitin- und Stearinsäure. Es wurde zwar bereits vorgeschlagen, niedrigmolekulare Halogenfettsäuren .mit Pyridinbasen umiusetzen, wobei in einigen Fällen unter Kohlendioxydabspaltung quaternäre Alkyl- bzw. Aralkylpyridiniumhalogenide gebildet werden; allein die Tatsache, daß bei den verschiedenen Pyridinbasen durchaus nicht in allen Fällen der oben angedeutete Umsetzungsverlauf eintritt, ließ nicht erwarten, daß die j a allgemein als wesentlich reaktionsträger bekannten hochmolekularen a-Halogenfettsäuren sich glatt mit @Pyridinbasen umsetzen würden. Die neuen Verbindungen stellen gute Netz- und Egalisierungsmittel dar. Beispiel i i o Teile a-Chlorlaurinsäure werden mit ioo Teilen Pyridin ia Stunden unter Rückfluß erhitzt. Das überschüssige Pyridin wird abdestilliert. Es entsteht das in (x-Stellung durch den Pyridinrest substituierte Produkt, das auch in saurer Lösung stark schäumende Lösungen gibt, die als Egalisiermittel verwendet werden. Beispiel 2 i5o,Teile a-lromstearinsäure werden mit 5oo Teilen Pyridin unter Rühren einige Zeit am RückfluB gekocht; hierauf wird das überschüssige Pyridin abdestilliert. Man erhält in ausgezeichneter Ausbeute die Pyridiniumverbindung, die beispielsweise aus Tetrachlorkohlenstoff umgelöst werden kann.The α-halogen derivatives, more saturated, are suitable for the process of high molecular weight fatty acids such as lauric, palmitic and stearic acid. It was Although already proposed, low molecular weight halogen fatty acids .mit pyridine bases react, in some cases with elimination of carbon dioxide quaternary alkyl or aralkylpyridinium halides are formed; just the fact that the different pyridine bases by no means in all cases the course of conversion indicated above enters, did not lead to the expectation that the j a were generally considered to be essentially unresponsive known high molecular weight a-halogen fatty acids react smoothly with @Pyridine bases would. The new compounds are good wetting and leveling agents. Example 100 parts of α-chloro lauric acid are refluxed with 100 parts of pyridine for ia hours heated. The excess pyridine is distilled off. This is created in (x-position product substituted by the pyridine residue, which foams strongly even in acidic solution There are solutions that are used as leveling agents. example 250 parts of α-chromostearic acid are mixed with 500 parts of pyridine while stirring Time boiled at reflux; the excess pyridine is then distilled off. The pyridinium compound is obtained in excellent yield, for example can be redissolved from carbon tetrachloride.
