Description

  

  Verfahren zur Herstellung eines neuen     Kondensationsproduktes.       Es wurde gefunden, dass man zu einem  neuen Kondensationsprodukt     gelangt,    wenn  man     ,u-IHeptadecyl-benzimidazol    in Gegen  wart einer Säure mit     Methylolchloracetamid     umsetzt und das so erhaltene Produkt mit       Pyridin    behandelt.  



  Als Säure wird     zweckmässig        konzentrierte     Schwefelsäure     verwendet.     



  Das neue Kondensationsprodukt bildet  eine feste Masse, die in Wasser unter starkem  Schäumen löslich ist und     kapillaraktive    Ei  genschaften besitzt. Es kann als     Tegtilhilfs-          stoff    verwendet werden.  



  <I>Beispiel:</I>  16     Teile,u-Heptadecylbenzimidazol    wer  den bei etwa 20' gelöst in 70 Teilen     kon-          zentrierter        Schwefelsäure.    Hierauf werden  unter Rühren bei etwa. 10   7     Teile    fein pul  verisiertes     Methylolchloracetamid    eingetragen       und    über Nacht bei gewöhnlicher Temperatur       weiter        gerührt.    Nach dem Eintragen in Eis  wasser,     Filtrieren,    Auswaschen     und    Trocknen  mit Wasser erhält man das Reaktionsprodukt    als eine weisse pulverige Masse.

   Dieselbe       wird    mit überschüssigem     Pyridin    auf dem  siedenden Wasserbade     verrührt,    bis eine  Probe in Wasser löslich ist. Nach dem Ab  destillieren des im Überschuss angewandten       Pyridins        unter    vermindertem Druck     stellt     das neue Kondensationsprodukt eine     feste     Masse dar, die in     Wasser        unter    Schäumen  löslich ist und     kapillaraktive    Eigenschaften       besitzt.  



  Process for the production of a new condensation product. It has been found that a new condensation product is obtained if u-IHeptadecyl-benzimidazole is reacted with methylolchloroacetamide in the presence of an acid and the product thus obtained is treated with pyridine.



  Concentrated sulfuric acid is expediently used as the acid.



  The new condensation product forms a solid mass, which is soluble in water with strong foaming and has capillary-active properties. It can be used as a textile auxiliary.



  <I> Example: </I> 16 parts of u-heptadecylbenzimidazole are dissolved in 70 parts of concentrated sulfuric acid at around 20 '. Then be stirred at about. 10 7 parts of finely pulverized methylolchloroacetamide entered and the mixture was stirred at ordinary temperature overnight. After pouring into ice water, filtering, washing out and drying with water, the reaction product is obtained as a white powdery mass.

   It is stirred with excess pyridine on the boiling water bath until a sample is soluble in water. After distilling off the pyridine used in excess under reduced pressure, the new condensation product is a solid mass that is soluble in water with foaming and has capillary-active properties.
