Abstract
In a solvent free system, hydrolytically stable nonionic surfactants, trisiloxane grafted Oligo(ethylene oxide), were synthesized by hydrosilylation of heptamethyltrisiloxane with allyl-oligo(EO) series. The structures of intermediate and products were confirmed by infrared spectroscopy and 1H nuclear magnetic resonance spectroscopy. Surface activity, foaming property and wetting ability of the surfactants were also investigated. The results show that the prepared surfactants exhibited excellent surface activity and wetting ability.
Kurzfassung
In einem lösungsmittelfreien System wurden trisiloxangepropfte Oligo(Ethylenoxide) als hydrolytisch stabile nichtionische Tenside durch Hydrosilylation von Heptamethyltrisiloxan mit Alyl-Oligo(EO)-Reihen synthetisiert. Die Strukturen der Zwischenprodukte und Produkte wurden durch Infrarot- und 1H-Kernresonanzspektroskopie bestätigt. Die Oberflächenaktivität, das Schaumverhalten und Benetzungsvermögen der Tenside wurden ebenfalls untersucht. Die Ergebnisse zeigen, dass die dargestellten Tenside ausgezeichnete Oberflächenaktivitäten und Schaumverhalten aufweisen.
