Description
Verfahren zur Herstellung eines neuen Derivates einer heterocyclischen Verbindung. Es wurde gefunden, dass man zu einem neuen Derivat einer heterocyclischen Verbin dung gelangt, wenn man das Natriumsalz des sulfonierten Benzimidazols, das durch Kondensation von o-Phenylendiamin mit technischer Stearinsäure und nachfolgende Sulfonierung erhalten wird, mit Glycerin-a- monochlorhydrin umsetzt,
auf das so erhal tene Reaktionsprodukt Äthylenoxyd einwir ken lässt und nachher das entstandene Um setzungsprodukt mit einer wässerigen Na triumhydroxydlösung behandelt.
Die Umsetzung mit dem Glycerin-a-mono- chlorhydrin erfolgt zweckmässig in Gegen wart eines Lösungsmittels, wie Xylol. Auch die Einwirkung des Athylenoxyds lässt man zweckmässig in der Wärme vor sieh gehen.
Das so erhaltene Produkt bildet nach dem Trocknen ein hellbraunes Pulver, dessen Lö sungen gegen schwache Säuren beständig sind. Es kann als Textilhilfsstoff, zum Bei spiel als Egalisiermittel, Anwendung finden.
<I>Beispiel:</I> 46 Gewichtsteile des Natriumsalzes Lies sulfonierten Benzimidazols, das durch Kon- densation von o-Phenylendiamin mit tech nischer Stearinsäure und nachfolgende Sulfo- nierung erhalten wird.
und 11 Gewichtsteile Glycerin-a-monochlorhydrin werden in 500 Volumteilen Xylol gelöst und die Lösung 12 Stunden unter Rühren zum Sieden erhitzt. Das Xylol wird hierauf unter vermindertem Druck abdestilliert, wobei die Reaktions masse als zäher Rückstand zurückbleibt.
Das so erhaltene Produkt wird mit 17,6 Gewichtsteilen Äthylenoxyd im Autoklaven unter Rühren während 12 Stunden auf 150 bis 160 erhitzt. Auf diese Weise erhält man ein Produkt, welches in Wasser fast unlöslich ist, welches sich aber nach Zusatz von so viel Lauge, dass .die Lösung phenolphthaleinalka- lisch reagiert, und kurzem Erwärmen klar löst.
Die alkalische Lösung wird neutral ge stellt und getrocknet. ATan erhält so ein hell- braunes Pulver. dessen wässerige Lösungen gegen sehiuache Säuren beständig sind.
Process for the preparation of a new derivative of a heterocyclic compound. It has been found that a new derivative of a heterocyclic compound is obtained if the sodium salt of sulfonated benzimidazole, which is obtained by condensation of o-phenylenediamine with technical stearic acid and subsequent sulfonation, is reacted with glycerol-a-monochlorohydrin,
Ethylene oxide can act on the reaction product obtained in this way and the resulting reaction product is then treated with an aqueous sodium hydroxide solution.
The reaction with the glycerol-a-monochlorohydrin is expediently carried out in the presence of a solvent such as xylene. The action of the ethylene oxide is also expediently allowed to take place in the warmth.
After drying, the product thus obtained forms a light brown powder, the solutions of which are resistant to weak acids. It can be used as a textile auxiliary, for example as a leveling agent.
<I> Example: </I> 46 parts by weight of the sodium salt Lies sulfonated benzimidazole, which is obtained by condensation of o-phenylenediamine with technical stearic acid and subsequent sulfonation.
and 11 parts by weight of glycerol-a-monochlorohydrin are dissolved in 500 parts by volume of xylene and the solution is heated to boiling for 12 hours while stirring. The xylene is then distilled off under reduced pressure, the reaction mass remaining as a viscous residue.
The product thus obtained is heated with 17.6 parts by weight of ethylene oxide in an autoclave with stirring to 150 to 160 hours. In this way, a product is obtained which is almost insoluble in water, but which dissolves clearly after adding so much alkali that the solution reacts in an alkaline phenolphthalein and briefly heating.
The alkaline solution is neutralized and dried. ATan is given a light brown powder. whose aqueous solutions are resistant to various acids.
