Abstract

A series ofbis-quaternary ammonium salts was easily prepared by the reaction of a long-chaintert-alkylamine with epichlorohydrin, and their surface-active properties were measured. The prepared amphipathic compounds had good water solubility and showed characteristic surface-active properties, particularly, extremely excellent foaming ability and foam stability for some specific compounds, such as the compound with a dodecyl and a tetradecyl group as the lipophilic chains. Their critical micelle concentration, which decreased with increased alkyl chainlength, is two orders of magnitude lower compared with the conventionalmono-quaternary ammonium salts. In comparison with surface-active properties ofbis-quaternary ammonium salts, prepared from various organic dichlorides, there are little differences based on the kind of connecting group in the surface-active properties except for foaming.
