Description

  

  Verfahren zur Herstellung eines neuen Derivates einer     heteroeyelisehen    Verbindung.    Es wurde gefunden, dass man zu einem  neuen Derivat einer     heteracyclischen    Verbin  dung gelangt, wenn man das     Natriumsalz     des sulfonierten     Benzimidazols,    das durch  Kondensation von     o-Phenylendiamin    mit  technischer     Stearinsäure    und nachfolgende       Sulfonierung    erhalten wird, mit     Athylenoxyd          i        msetzt,

      auf das so erhaltene Reaktionspro  dukt     Dimethylsulfat    einwirken lässt und das       entstandene    Reaktionsprodukt mit einer  wässerigen     Natriumhydroxydlösung    behan  delt.  



  Die Einwirkung des     Athylenoxyds    und  des     Dimethylsulfates    erfolgt zweckmässig in  der     Wärme.     



  Das so erhaltene Produkt stellt nach dem  Trocknen eine feste, braune Masse dar, die  in Wasser löslich und gegen Essigsäure be  ständig ist. Es kann als     Textilhilfsstoff,    zum  Beispiel als     Egalisieimittel,    Anwendung fin  den.

      <I>Beispiel:</I>  46 Gewichtsteile des     Natriumsalzes    des       sulfonierten        Benzimidazols,    das durch Kon  densation von o-Phenylendiamin mit tech  nischer     Stearinsäure        und    nachfolgende     Sulfo-          nierung    erhalten wird, werden mit 17,6 Ge  wichtsteilen     Äthylenoxyd    im     Autoklaven    12  Stunden .auf     150-160'    erhitzt. Das so erhal  tene Produkt wird mit 12,6     Gewichtsteilen          Dimethylsulfat    noch 3 Stunden unter Rühren  auf<B>100.-110'</B> erwärmt.

   Das entstandene  Produkt ist in Wasser fast unlöslich; es löst  sich in     phenolphthaleinalkalischer    Lösung  bei kurzem Erwärmen und stellt nach dem  Trocknen     eine    feste, braune Masse dar, die  in Wasser löslich und gegen Essigsäure     be-          ständiz    ist.



  Process for the preparation of a new derivative of a heteroeyelic compound. It has been found that a new derivative of a heteracyclic compound is obtained if the sodium salt of sulfonated benzimidazole, which is obtained by condensation of o-phenylenediamine with technical stearic acid and subsequent sulfonation, is mixed with ethylene oxide,

      Dimethyl sulfate is allowed to act on the reaction product obtained in this way and the reaction product formed is treated with an aqueous sodium hydroxide solution.



  The ethylene oxide and dimethyl sulfate are expediently exposed to heat.



  The product obtained in this way, after drying, is a solid, brown mass which is soluble in water and is constantly be against acetic acid. It can be used as a textile auxiliary, for example as a leveling agent.

      <I> Example: </I> 46 parts by weight of the sodium salt of sulfonated benzimidazole, which is obtained by condensation of o-phenylenediamine with technical stearic acid and subsequent sulfonation, are mixed with 17.6 parts by weight of ethylene oxide in the autoclave for 12 hours. heated to 150-160 '. The product obtained in this way is heated with 12.6 parts by weight of dimethyl sulfate for a further 3 hours while stirring to 100-110 '.

   The resulting product is almost insoluble in water; it dissolves in phenolphthalein-alkaline solution when heated briefly and, after drying, represents a solid, brown mass which is soluble in water and resistant to acetic acid.
