Abstract

A new group of nonionic ester surfactants was synthesized. New esters were obtained in high yields from commercially available poly(oxyalkylated) alcohols and fatty acid chlorides under mild reaction conditions. Their structures were confirmed by GPC and HPLC chromatography. The surface properties such as critical micelle concentration (c.m.c.), surface excess concentration, Gc.m.c., and surface area per molecule, Ac.m.c., were determined. The emulsification properties of the new esters were investigated.

Kurzfassung

Eine neue Gruppe von nichtionischen Estertensiden wurde synthetisiert. Neue Ester aus kommerziell verfügbaren polyoxalkylierten Alkoholen und Fettsäurechloriden wurden in hoher Ausbeute unter milden Bedingungen erhalten. Ihre Struktur wurde durch GPC und HPLC-Chromatographie bestätigt. Die Oberflächeneigenschaften wie die kritische Mizellbildungskonzentration (c.m.c.), Oberflächen-Excess-Konzentration, Gc.m.c., und Oberflächenareal pro Molekül, Ac.m.c., wurden bestimmt. Die Emulgiereigenschaften der neuen Ester wurden untersucht.
