Description

  

  Verfahren zur Herstellung eines     Kondensationsproduktes.       Es wurde gefunden, dass man ein Kon  densationsprodukt erhält, das auf Grund sei  ner     kapillaraktiven    Eigenschaften als Netz-,       Dispergier-,        Emulgier-,    Wasch- und Reini  gungsmittel in der Textilindustrie und Fär  berei Verwendung finden kann, wenn man       2-Heptadecyl-d -=midazolin,    Formaldehyd und       Natriumbisulfit    aufeinander einwirken lässt.

    Die Umsetzung verläuft nach folgendem  Schema:  
EMI0001.0007     
    Es entsteht das     Natriumsalz    der     2-Heptade-          cyl-d2-imidazolin-l-methansulfosäure,    das ein  hellgelbes, körniges Produkt darstellt.

      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 von Formaldehyd und     Natriumbi-          sulfid.    Man kann zunächst den Formaldehyd  auf das     Natriumbisulfit    einwirken lassen, zum  Beispiel auch in Gegenwart des     2-Heptade-          cyl-d2-imidazolins.     



  <I>Beispiele:</I>  1. In 29,4 g     2-Heptadecyl-d2-imidazo-          lin    werden bei 95-100  C langsam 27 g       Formaldehydnatriumbisulfit    eingetragen. Die  Schmelze wird bis zur Wasserlöslichkeit auf  <B>120-1300</B> C erhitzt. Nach etwa einer Stunde  ist die Reaktion beendet. Nach dem Erkalten  wird der Schmelzkuchen zerkleinert. Ausbeute  55 g. Das hellgelbe, körnige Produkt ist unter  Schäumen leicht in Wasser löslich,      2.

   Zu einer wässerigen Lösung von einem       Mol        Formaldehyd-Natriumbisulfit    in etwa der  vierfachen Menge Wasser lässt man bei etwa  450 C unter Rühren eine Lösung von 0,9       Mol        2-Heptadeoyl-d2-imidazolin    in der doppel  ten Menge Alkohol langsam zufliessen. Nach  erfolgter     Zumischung    wird noch so lange auf  etwa 50   C unter Rühren erwärmt, bis eine  Probe sich in Wasser klar löst. Hierauf wird  zur Trockne gebracht.



  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, detergent and cleaning agent in the textile industry and dyeing, if 2-heptadecyl-d - = lets midazoline, formaldehyde and sodium bisulfite interact.

    The implementation proceeds according to the following scheme:
EMI0001.0007
    The result is the sodium salt of 2-heptadecyl-d2-imidazoline-1-methanesulfonic acid, which is a light yellow, granular product.

      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 disulfide. You can first let the formaldehyde act on the sodium bisulphite, for example in the presence of 2-heptadecyl-d2-imidazoline.



  <I> Examples: </I> 1. 27 g of sodium formaldehyde bisulfite are slowly added to 29.4 g of 2-heptadecyl-d2-imidazoline at 95-100 ° C. The melt is heated to <B> 120-1300 </B> C until it is water-soluble. The reaction has ended after about an hour. After cooling, the melting cake is crushed. Yield 55g. The light yellow, granular product is easily soluble in water with foaming, 2.

   A solution of 0.9 mol of 2-heptadeoyl-d2-imidazoline in twice the amount of alcohol is allowed to slowly flow into an aqueous solution of one mole of formaldehyde-sodium bisulfite in about four times the amount of water at about 450 ° C. with stirring. After mixing, the mixture is heated to about 50 C with stirring until a sample dissolves clearly in water. It is then brought to dryness.
