Description

  

  Verfahren zur Herstellung eines neuen Hilfsstoffes für die Textilindustrie.    Es wurde gefunden, dass man einen neuen       Hilfsstoff    für die Textilindustrie erhält, wenn  man das     Imidazolgemisch,    das entsteht     dureh          Kondensieren    von     o-Phenylendiamin    mit dem  technischen Gemisch der Stearin- und     Pal-          mitinsäure,    wie es aus Rindertalg gewonnen  wird, mit erschöpfend     methylierend    wirken  den Mitteln behandelt.  



  Der neue Hilfsstoff bildet in Form seiner  mineralsauren Salze ein kaum gefärbtes Pul  ver mit den Eigenschaften der sogenannten       sauren    Seifen. Er soll als     Hilfsstoff    in der  Textilindustrie verwendet werden.  



  <I>Beispiel:</I>       AATan    stellt ein Gemisch von     Pentadecyl-          und        Heptadecylbenzimidazol    durch Erhitzen  von 100 Teilen des technischen Gemisches  von     Stearin-Palmitinsäure,    wie es aus Rinder  talg gewonnen wird, mit, 41 Teilen     o-Pheny-          lendia,min    her, das man auf 140-120   ab  kühlen     lä,sst,    worauf man 356 Teile des     Benz-          imidazolgemisches    mit 1500 Teilen     Trichlor-          benzol    vermischt und das Gemenge auf 150    erhitzt.

      Unter stetem Rühren lässt man zu dieser  Lösung allmählich 130 Teile     Dimethylsulfat     zufliessen und erhitzt dann die Reaktions  masse weitere 6 Stunden auf 150  . Sodann  fügt man     zii        letzterem    206 Teile Soda in  fein pulverisierter Form und dann nochmals  130 Teile     Dimethylsulfat.    Nach weiterem  zwei- bis dreistündigem Rühren der Reak  tionsflüssigkeit bei 150   wird vom ungelösten  Anteil heiss     abfiltriert,    worauf beim Erkalten  des Filtrates das Reaktionsprodukt als farb  loses, kristallines Pulver ausfällt, das abge  saugt und mit Benzol gewaschen wird.  



  Man erhält auf diese Weise die     quater-          nären        Ammoniumsalze    der     methylierten    Benz  imidazole der Formel  
EMI0001.0032     
      in welcher an Stelle von     Ri        Heptadecyl-    und       Pentadecylreste    zu setzen sind, als farbloses,  kristallinisches Pulver, das in heissem Wasser  unter Bildung stark schäumender Lösungen  löslich ist.



  Process for the production of a new auxiliary material for the textile industry. It has been found that a new auxiliary material for the textile industry is obtained if the imidazole mixture, which is formed by condensing o-phenylenediamine with the technical mixture of stearic and palmitic acid, as obtained from beef tallow, has an exhaustive methylating effect treated the means.



  In the form of its mineral acid salts, the new auxiliary forms a hardly colored powder with the properties of so-called acid soaps. It is said to be used as an auxiliary in the textile industry.



  <I> Example: </I> AATan produces a mixture of pentadecyl- and heptadecylbenzimidazole by heating 100 parts of the technical mixture of stearic-palmitic acid, as it is obtained from bovine tallow, with 41 parts of o-phenylendia, min which is allowed to cool to 140-120, whereupon 356 parts of the benzimidazole mixture are mixed with 1500 parts of trichlorobenzene and the mixture is heated to 150.

      With constant stirring, 130 parts of dimethyl sulfate are gradually added to this solution and the reaction mass is then heated to 150 for a further 6 hours. Then 206 parts of finely powdered soda are added to the latter, followed by another 130 parts of dimethyl sulfate. After stirring the reac tion liquid for a further two to three hours at 150, the undissolved portion is filtered off hot, whereupon the reaction product precipitates as a colorless, crystalline powder when the filtrate cools, which is filtered off with suction and washed with benzene.



  In this way, the quaternary ammonium salts of the methylated benzimidazoles of the formula are obtained
EMI0001.0032
      in which heptadecyl and pentadecyl radicals are to be used in place of Ri, as a colorless, crystalline powder that is soluble in hot water with the formation of strongly foaming solutions.
