Description
Verfahren zur Herstellung eines Imidazolderivates. Es wurde gefunden, dass man ein neues Imidazolderivat erhält, wenn man ss-Methyl- benzimidazol mit einem Ester des Cetylalko- hols behandelt. Das neue Imidazolderivat verbindet sich mit Mineralsäuren zu Salzen, z.
B. mit Salzsäure zum N-Cetyl-ss-methyl- benzimidazolhydrochlorid, das mit Wasser stark schäumende Lösungen gibt und ein ausgezeichnetes Weichmachungsmittel für Viskosekunstseide darstellt.
Beispiel: 52 Teile u-Methylbenzimidazol werden mit 10-1 Teilen Cetylchlorid während etwa 8 Stunden bei<B>1600</B> gerührt. Sobald eine Probe der Reaktionsmasse sich in angesäuer tem Wasser klar löst, unterbricht man das weitere Erhitzen, wobei nach dein Eikalten das Reaktionsprodukt als eine talgige Masse ei-halten wird, die nötigenfalls durch Auf nahme in Alkohol und Entfärben mit Tier kohle völlig entfärbt werden kann.
Process for the preparation of an imidazole derivative. It has been found that a new imidazole derivative is obtained if β-methylbenzimidazole is treated with an ester of cetyl alcohol. The new imidazole derivative combines with mineral acids to form salts, e.g.
B. with hydrochloric acid to N-cetyl-ss-methylbenzimidazole hydrochloride, which gives strong foaming solutions with water and is an excellent softener for rayon.
Example: 52 parts of u-methylbenzimidazole are stirred with 10-1 parts of cetyl chloride for about 8 hours at <B> 1600 </B>. As soon as a sample of the reaction mass dissolves clearly in acidified water, the further heating is interrupted, whereby after the egg cold the reaction product is kept as a tallowy mass, which if necessary can be completely decolorized by absorption in alcohol and decolorization with animal charcoal .
