Description

  

  Verfahren zur Herstellung eines     Kondensationsproduktes.       Es wurde gefunden, dass man ein Kon  densationsprodukt erhält, das auf Grund seiner       kapillaraktiven    Eigenschaften als Netz-, Dis  pergier-,     Emulgier-,    Wasch- und Reinigungs  mittel in der Textilindustrie und Färberei  Verwendung finden kann, wenn man     2-Hepta-          decenyl-42-imidazolin,    Formaldehyd und       Natriumbisulfit    aufeinander einwirken lässt.  Die Umsetzung verläuft nach folgendem  Schema:  
EMI0001.0007     
    Es entsteht das     Natriumsalz    der     2-Heptade-          cenyl-d2-imidazolin-l-methansulfosäure.     



  Man kann die Umsetzung in Lösungs-    oder Verdünnungsmitteln, zweckmässig unter  Erwärmen, durchführen; man kann aber auch  die Komponenten direkt ohne Zuhilfenahme  von Lösungsmitteln zur Reaktion bringen,  gegebenenfalls unter Verwendung eines Über  schusses an Formaldehyd und     Natriumbisulfit.     Man kann zunächst den Formaldehyd auf  das     Natriumbisulfit    einwirken lassen; z. B.

    auch in Gegenwart des     2-Heptadecenyl-d2-          imidazolins.       <I>Beispiel:</I>    In 1     DZol        2-Heptadecenyl-d2-imidazolin     werden bei 110-120   C langsam 2     Mol    des  Reaktionsproduktes aus Formaldehyd und       Natriumbisulfit    eingetragen. Die Schmelze  wird bis zur Wasserlöslichkeit auf 150 bis  <B>160</B>   C erhitzt. Nach etwa 1 Stunde ist die  Reaktion beendet. Nach dem Erkalten wird  der Schmelzkuchen zerkleinert. Das hell  gelbe, körnige Produkt ist unter Schäumen  in Wasser löslich.



  Process for the production of a condensation product. It has been found that a condensation product is obtained which, due to its capillary-active properties, can be used as a wetting, dispersing, emulsifying, washing and cleaning agent in the textile industry and dyeing, if 2-heptadecenyl 42-imidazoline, formaldehyde and sodium bisulfite interact. The implementation proceeds according to the following scheme:
EMI0001.0007
    The sodium salt of 2-heptadecenyl-d2-imidazoline-1-methanesulfonic acid is formed.



  The reaction can be carried out in solvents or diluents, expediently with heating; however, the components can also be reacted directly without the aid of solvents, if appropriate using an excess of formaldehyde and sodium bisulfite. You can first let the formaldehyde act on the sodium bisulfite; z. B.

    also in the presence of 2-heptadecenyl-d2-imidazoline. <I> Example: </I> 2 mol of the reaction product of formaldehyde and sodium bisulphite are slowly introduced into 1 dzol of 2-heptadecenyl-d2-imidazoline at 110-120 C. The melt is heated to 150 to <B> 160 </B> C until it is water-soluble. The reaction has ended after about 1 hour. After cooling, the melting cake is crushed. The light yellow, granular product is soluble in water with foaming.
