Description

  

  Verfahren zur Herstellung einer neuen     Sulfonsäure.       Es wurde gefunden, dass man eine neue       Sulfonsäure    erhält,     wenn    man das     Imidazol-          gemisch,    das entsteht durch Kondensieren  von     o-Phenylendiamin    mit dem technischen  Gemisch der Stearin- und     Palmitinsäure,    wie  es aus Rindertalg gewonnen wird, mit     sul-          fierend    wirkenden Mitteln behandelt.  



  Die neue     Sulfonsäure    bildet in Form  ihrer     Alkalisalze    ein kaum gefärbtes Pulver  mit ausgesprochen seifenartigen Eigenschaf  ten. Sie soll als Hilfsstoff in der Textil  industrie verwendet werden.  



  <I>Beispiel:</I>  Man stellt ein Gemisch von     Pentadecyl-          und        Heptadecylbenzimidazol    durch Erwär  men des technischen Gemisches von     Stearin-          Palmitinsäure,    wie es aus Rindertalg ge  wonnen wird, mit 41 Teilen     .o-Phenylen-          diamin    her.  



  In 75 Teile     Chlorsulfousäure,    die auf 5  bis<B>10'</B> abgekühlt und gerührt werden,  <I>trägt man</I> allmählich 25 Teile des Benzimid-         azolgemisches    ein und rührt das Gemisch bei  20 bis 25   so lange, bis eine herausgenom  mene Probe sich in verdünnter Sodalösung  klar auflöst.  



  Die Reaktionsmasse wird sodann in eis  gekühlte gesättigte     Kochsalzlösung    ein  gerührt, wobei das sulfonierte Produkt sich  als eine nach kurzer Zeit erstarrende Masse  abscheidet, die abgesaugt     wird.     



  Das so erhaltene Produkt wird in heissem  Wasser suspendiert, und durch Zusatz von  Natronlauge neutralisiert, wobei eine klare,  stark schäumende Lösung erhalten wird,  aus der durch Eindampfen das     Natriumsalz     der entsprechenden     Benzimidazol-sulfonsäure     gewonnen wird.



  Process for the preparation of a new sulfonic acid. It has been found that a new sulfonic acid is obtained if the imidazole mixture, which is formed by condensation of o-phenylenediamine with the technical mixture of stearic and palmitic acid, as it is obtained from beef tallow, is treated with sulphurizing agents .



  In the form of its alkali salts, the new sulfonic acid forms a hardly colored powder with pronounced soap-like properties. It is intended to be used as an auxiliary in the textile industry.



  <I> Example: </I> A mixture of pentadecylbenzimidazole and heptadecylbenzimidazole is produced by heating the technical mixture of stearic-palmitic acid, as it is obtained from beef tallow, with 41 parts of .o-phenylenediamine.



  25 parts of the benzimidazole mixture are gradually introduced into 75 parts of chlorosulphous acid, which are cooled to 5 to 10 ′ and stirred, and the mixture is stirred at 20 to 25 for as long until a sample taken out dissolves clearly in dilute soda solution.



  The reaction mass is then stirred into ice-cooled saturated sodium chloride solution, the sulfonated product separating out as a mass which solidifies after a short time and which is filtered off with suction.



  The product obtained in this way is suspended in hot water and neutralized by adding sodium hydroxide solution, a clear, highly foaming solution being obtained from which the sodium salt of the corresponding benzimidazole sulfonic acid is obtained by evaporation.
