Description

  

  Verfahren zur Herstellung eines     gondensätionsproduktes.       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-Un-          decyl-d2-imidazolin,    Formaldehyd und     Na-          triumbisulfit    aufeinander einwirken lässt.

   Die  Umsetzung verläuft nach folgendem Schema:  
EMI0001.0008     
    Es entsteht das     Natriumsalz    der     2-Undecyl-          d2-imidazolin-l-methansulfosäure.     



  Man kann die Umsetzung auch 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     Natriumbisalfit.     Man kann zunächst den Formaldehyd auf  das     Natriumbisulfit    einwirken lassen, z. B.  auch in     fäegenwart    des     2-Undecyl-dZ-imid-          azolins.     



  <I>Beispiel:</I>  In 1     Mol        2-Undecyl-d2-imidazolin    werden  bei 95-100   C langsam 2     Mol    des Reak  tionsproduktes aus Formaldehyd     undNatrium-          bisulfit    eingetragen. Die Schmelze wird bis  zur Wasserlöslichkeit auf 120-130   C er  hitzt. Nach etwa 1 Stunde ist die Reaktion  beendet. Nach dem Erkalten wird der Schmelz  kuchen zerkleinert. Das hellgelbe, körnige  Produkt ist unter Schäumen in Wasser leicht  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-undecyl d2-imidazoline, formaldehyde and sodium bisulphite interact.

   The implementation proceeds according to the following scheme:
EMI0001.0008
    The sodium salt of 2-undecyl-d2-imidazoline-1-methanesulfonic acid is formed.



  The reaction can also 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 bisalfit. You can first let the formaldehyde act on the sodium bisulfite, z. B. also in the presence of 2-undecyl-dZ-imid-azoline.



  <I> Example: </I> 2 mol of the reaction product of formaldehyde and sodium bisulfite are slowly introduced into 1 mol of 2-undecyl-d2-imidazoline at 95-100 C. The melt is heated to 120-130 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 easily soluble in water with foaming.
