Description

  

  Verfahren zur Herstellung eines neuen Derivates einer     heterocyclischen    Verbindung.    Es wurde gefunden, dass man zu einem  neuen Derivat einer     heterocyclischen    Verbin  dung gelangt, wenn man das     Natriumsalz    des  sulfonierten     Benzimidazols,        welches    durch  Kondensation von     o-Phenylendiamin    mit ge  härteter     Tranfettsäure    und nachfolgende     Sul-          fonierungerhalten    wird,

   mit     Chloracetamid     umsetzt und darauf     Äthylenoxyd    auf     das     so erhaltene     Umsetzungsprodukt    einwirken  lässt.  



  Die Umsetzung mit dem     Chloracetamid     wird zweckmässig in der Wärme,     vorteilhaft     in Gegenwart von Lösungsmitteln, wie     Xylol,     vorgenommen. Auch die Einwirkung des       Äthylenoxyds    lässt man zweckmässig in der  Wärme vor sich gehen.  



  Das so erhaltene Produkt stellt eine  dunkle, zähe Masse dar, welche     alkalilöslich     und gegen Essigsäure beständig ist. Es kann  als     Textilhilfssto.ff,    zum Beispiel als     Egali-          3iermittel,    Anwendung finden.

           Beispiel:     46     Gewichtsteile    des     Natriumsalzes    des  sulfonierten     Benzimidazols,    welches durch  Kondensation von     o-Phenylendiamin    mit ge  härteter     Tranfettsäure    und nachfolgende     Sul-          fonierung    erhalten wird, und 9,3 Gewichts  teile     Chloracetamid        werden,    in     Xylol    gelöst  und die Lösung 12     Stunden    unter Rühren  zum Sieden erhitzt.

   Das     Xylol        wird    hierauf  unter vermindertem Druck     abdestilliert.     



  Das entstandene Produkt wird mit  17,6     Gewichtsteilen        Äthylenoxyd    12 Stunden  im     Autoklaven    auf 150-160   erhitzt. Man  erhält     eine    dunkle, zähe Masse, welche     alkali-          iöslich        und    gegen Essigsäure beständig     ist.  



  Process for the preparation of a new derivative of a heterocyclic compound. It has been found that a new derivative of a heterocyclic compound is obtained if the sodium salt of sulfonated benzimidazole, which is obtained by condensation of o-phenylenediamine with hardened trans-fatty acid and subsequent sulfonation,

   reacts with chloroacetamide and then allows ethylene oxide to act on the reaction product thus obtained.



  The reaction with the chloroacetamide is expediently carried out in the heat, advantageously in the presence of solvents such as xylene. The action of ethylene oxide is also expediently allowed to proceed in the warmth.



  The product obtained in this way is a dark, viscous mass which is alkali-soluble and resistant to acetic acid. It can be used as a textile auxiliary, for example as a leveling agent.

           Example: 46 parts by weight of the sodium salt of sulfonated benzimidazole, which is obtained by condensation of o-phenylenediamine with hardened trans-fatty acid and subsequent sulfonation, and 9.3 parts by weight of chloroacetamide are dissolved in xylene and the solution is boiled for 12 hours with stirring heated.

   The xylene is then distilled off under reduced pressure.



  The resulting product is heated to 150-160 in an autoclave with 17.6 parts by weight of ethylene oxide for 12 hours. A dark, viscous mass is obtained which is soluble in alkali and resistant to acetic acid.
