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 das Imidazolingemisch, das aus Äthylendiamin und dem aus Kokosöl gewonnenen Fettsäure gemisch erhältlich ist, Formaldehyd und Na- triumbisulfit aufeinander einwirken lässt.
Die Umsetzung verläuft nach folgendem Schema:
EMI0001.0008
wobei R-C für die Reste der im gokosöl enthaltenen Fettsäuren steht. Es entsteht ein Gemisch von Natrium salzen von 2-Alkyl-42-imidazolin-l-methan- sulfosäuren.
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 Imidazolingemisches, das aus Äthylendiamin und dem aus Kokosöl gewonnenen Fettsäuregemisch erhältlich ist.
<I>Beispiel:</I> In 1 Mol des Imidazolingemisches, das aus Äthylendiamin und dem aus gokosö.l gewonnenen Fettsäuregemisch erhältlich ist, werden bei 95-100 C langsam 2 Mol des Reaktionsproduktes aus Formaldehyd und Natriumbisulfit eingetragen. Die Schmelze wird bis zur Wasserlöslichkeit auf 120 bis 130 C erhitzt.
Nach etwa 1 Stunde ist die Reaktion beendet. Naeh dein Erkalten wird der Schmelzkuehen zerkleinert. Das hellgelbe, körnige Produkt ist unter Schäumen leicht 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, detergent and cleaning agent in the textile industry and dyeing, if one uses the imidazoline mixture consisting of ethylene diamine and the fatty acid mixture obtained from coconut oil, allows formaldehyde and sodium bisulfite to interact.
The implementation proceeds according to the following scheme:
EMI0001.0008
where R-C stands for the residues of the fatty acids contained in the goo oil. A mixture of sodium salts of 2-alkyl-42-imidazoline-1-methanesulfonic acids is formed.
The reaction can be carried out in solvents or diluents, expediently with heating; but you can also bring the components to react 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 the imidazoline mixture, which is available from ethylenediamine and the fatty acid mixture obtained from coconut oil.
<I> Example: </I> 2 mol of the reaction product of formaldehyde and sodium bisulfite are slowly added to 1 mol of the imidazoline mixture, which is available from ethylenediamine and the fatty acid mixture obtained from gokosö.l. The melt is heated to 120 to 130 ° C until it is water-soluble.
The reaction has ended after about 1 hour. After your cold, the melting cows will be crushed. The light yellow, granular product is easily soluble in water with foaming.
