| Abstract: | ABSTRACT Micellar mimetic ionenes are linear cationic polyelectrolytic molecules having dimethylammonium charge centers interconnected by alternating alkyl chain segments containing x and y number of methylene groups where x is equal to 3 and y is greater than 14. These ionenes form intramolecular aggregates with behavior that mimics traditional surfactant micelle properties. In this paper we report the use of 3, 16]-ionene to prepare an in situ generated stationary phase on aminopropylated silica for liquid chromatography. This phase was found to exhibit chromatographic characteristics different from those of conventional amino, C-18 or phenyl stationary phases. This ionene column has facilitated the separation of some cis-, trans-, and ortho-, meta-, para-isomeric components, planar and non-planar aromatic hydrocarbons as well as alpha - beta ring attachment compounds. |
