Description

  

  *Verfahren zur Herstellung eines     Imidazolderivates.       Es wurde gefunden, dass man ein neues       Imidazolderivat    erhält, wenn man     Benzimi-          dazol    mit einem Ester des     Laurylalkohols     behandelt. Das neue     Imidazolderivat    verbin  det sich mit Mineralsäure zu Salzen, z. B.

    mit Salzsäure zum     N-Lauryl-berizimidazol-          hydrochlorid,    das mit Wasser stark     scbäu-          mende    Lösungen gibt und ein ausgezeich  netes     Weichmachungsmittel    für     Tiskose-          kunstseide    darstellt.    <I>Beispiel</I>    49 Teile     Benzimidazol    werden mit 80  Teilen     Laurylchlorid    während etwa 8 Stun  den bei<B>1600</B> gerührt.

   Sobald eine Probe der  Reaktionsmasse sich in angesäuertem Wasser  klar löst, unterbricht man das weitere Er  hitzen, wobei nach dem Erkalten das Reak-         tionsprodukt    als eine talgige Masse erhalten  wird, die nötigenfalls durch Aufnahme in  Alkohol und Entfärben mit Tierkohle völlig  entfärbt werden kann.



  * Process for the production of an imidazole derivative. It has been found that a new imidazole derivative is obtained if benzimidazole is treated with an ester of lauryl alcohol. The new imidazole derivative connects with mineral acid to form salts such. B.

    with hydrochloric acid to form N-lauryl-berizimidazole hydrochloride, which gives strong foaming solutions with water and is an excellent softening agent for artificial silk. <I> Example </I> 49 parts of benzimidazole are stirred with 80 parts of lauryl chloride for about 8 hours at <B> 1600 </B>.

   As soon as a sample of the reaction mass dissolves clearly in acidified water, further heating is interrupted, whereby after cooling the reaction product is obtained as a tallowy mass which, if necessary, can be completely decolorized by absorption in alcohol and decolorization with animal charcoal.

PATENTANSPRUCH: Verfahren zur Herstellung eines reuen Imidazolderivates, dadurch gekennzeichnet, dass man Benzimidazol mit einem Ester des Laurylalkohols behandelt. Das neue Imida- zolderivat verbindet sich mit Mineralsäuren zu Salzen, z. B. mit Salzsäure zum N-Lau- rylbenzimidazolhydrochlorid, das mit Wasser stark schäumende Lösungen gibt und ein ausgezeichnetes Weichmachungsmittel für Viskosekunstseide darstellt. PATENT CLAIM: Process for the production of a pure imidazole derivative, characterized in that benzimidazole is treated with an ester of lauryl alcohol. The new imidazole derivative combines with mineral acids to form salts, e.g. B. with hydrochloric acid to N-laurylbenzimidazole hydrochloride, which gives strong foaming solutions with water and is an excellent softener for rayon.
