Abstract

This paper describes an efficient method for the synthesis of long chain alkylamido imidazolines by the reaction of diethylenetriamine and oleic acid under non-solvent microwave irradiation using calcium oxide as support and their comparison with conventional thermal condensation process. Synthesized imidazolines were then quaternized by using dimethylsulfate as a quaternizing agent and isopropanol as a solvent, to produce cationic imidazolinium salts which were evaluated for yield and cationic content. The instrumental techniques, viz. FT-IR and 1H-NMR verified the formation of imidazolines and its subsequent quaternization. The surface active and performance properties of cationic imidazolines in terms of c.m.c., surface tension, dispersability, emulsion stability, softening, rewettability and detergency were also reported.

Kurzfassung

Diese Arbeit beschreibt eine effiziente Methode zur Synthese von langkettigen Alkylamidoimidazolinen durch Reaktion von Diethylentriamin und Ölsäure unter lösungsmittelfreier Mikrowellenbestrahlung mit Kalziumoxid als Hilfsmittel im Vergleich zu konventionellen thermischen Kondensationsverfahren. Die synthetisierten Imidazoline wurden mit Dimethylsulfat als Quaternisierungsmittel und Isopropanol als Lösungsmittel zur Darstellung von kationischen Imidazoliniumsalzen quaternisiert, die dann nach Ausbeute und kationischem Gehalt bewertet wurden. Die instrumentellen Methoden, und zwar FT-IR and 1H-NMR verifizieren die Ausbildung von Imidazolinen mit nachfolgender Quaternisierung. Über die oberflächenaktiven und Leistungseigenschaften bezüglich c.m.c., Oberflächenspannung, Dispergierbarkeit, Emulsionsstabilität, Weichmachung, Wiederbenetzung und Waschkraft wird ebenfalls berichtet.
