Description

  

  Verfahren zur Herstellung     einei#    neuen     Sulfosäure.       Es wurde gefunden, dass man eine neue       Sulfosäure    erhält,     -wenn    man den     Benzimid-          azol-,u-thio-dodecyl-äther,    beispielsweise er  halten durch Kondensation von     ic-1VIerkapto-          benzimidazol    mit     Dodecylchlorid,    mit     sul-          fierend    wirkenden Mitteln behandelt.  



  Die neue     Sulfosäure    bildet in Form ihrer       Alkalisalze    ein kaum gefärbtes Pulver mit  ausgesprochen seifenartigen Eigenschaften.  Sie soll als Hilfsstoff in der Textilindustrie  verwendet werden.  



  <I>Beispiel:</I>  10 Teile     Benzimidazol-,cc-thio-dodecyl-          lither    werden mit 20 Teilen Schwefelsäure  monohydrat einige Zeit bei 0 bis 5   ver  rührt. Hierauf giesst man die     Sulfurierungs-          masse    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 sulfonic acid is obtained when the benzimidazole, u-thio-dodecyl ether, for example, he keeps by condensation of ic-1VIerkaptobenzimidazole with dodecyl chloride, treated with sulfating agents.



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



  <I> Example: </I> 10 parts of benzimidazole, cc-thio-dodecyl lither are stirred with 20 parts of sulfuric acid monohydrate at 0 to 5 for some time. The sulfurizing mass is then poured onto ice, the separated sulfonic acid 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.
