Description

  

  Verfahren zur Herstellung einer neuen     Sulfosäure.       Es wurde gefunden, dass man eine neue       5ulfosä.ure    erhält, wenn man den     Benzimid-          i        ii        zol        -it-propionsiiure-dodecylester,        beispiels-          weise    erhalten durch     Veresterung    von     Benz-          imidazol-,cc-propionsäure    mit     Dodecylalkohol,     mit     sulfierend    wirkenden Mitteln behandelt.  



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

           Beispiel:       Bei 0 bis 3 " streut man in 50 Teile       _@    ö     igen        Oleums        1,1    Teile     Benzimidazol-,u-          propionsäure-dodecylester    ein.     'Nachdem    sich  derselbe aufgelöst hat, werden     ?0    Teile       ?1%iges        Oleum        hinzufliessen    gelassen und  solange bei der angegebenen Temperatur  gerührt, bis eine Probe der Reaktionsmasse  sich in verdünnter     Natriumhydroxydlösung     vollständig auflöst.

   Sobald dieser Zustand  erreicht ist, giesst man das     Sulfurierungsge-          misch    auf Eis, filtriert die abgeschiedene         Sulfosäure    ab, wäscht sie mit Wasser und  führt sie gegebenenfalls in ihr     Alkalisalz     über. Das trockene     Natriumsalz    kann zum  Beispiel aus einer wässerigen Lösung durch  Eindampfen im Vakuum bei     40    bis<B>50'</B> er  halten werden. Es bildet ein farbloses Pul  ver, das sich in Wasser unter Bildung stark  schäumender Lösungen löst, die ausgezeich  nete     Dispergier-,    Wasch- und     Egalisiereigen-          schaften    besitzen.



  Process for the preparation of a new sulfonic acid. It has been found that a new 5ulfosä.ure is obtained when the benzimid i ii zol -it-propionsiiure-dodecyl ester, for example obtained by esterification of benzimidazole, cc-propionic acid with dodecyl alcohol, with sulfating agents treated.



       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.

           Example: At 0 to 3 ", 1.1 parts of benzimidazole and u-propionic acid dodecyl ester are sprinkled into 50 parts of oleum. After it has dissolved," 0 parts "of 1% oleum are allowed to flow in and Stirred at the specified temperature until a sample of the reaction mass completely dissolves in dilute sodium hydroxide solution.

   As soon as this state has been reached, the sulphuration mixture is poured onto ice, the sulphonic acid which has separated out is filtered off, washed with water and, if necessary, converted into its alkali salt. The dry sodium salt can, for example, be obtained from an aqueous solution by evaporation in a vacuum at 40 to 50 '. It forms a colorless powder that dissolves in water to form strongly foaming solutions that have excellent dispersing, washing and leveling properties.
