| Abstract: | Pure oleic acid and four hydrolyzed products of locally fatty oils (namely, coconut, soybean, linseed, and castor oils) were monoesterified individually with two different polyalkylene polyamines. The produced monoesters were used as precursors for imidazoline derivatives. These oil soluble imidazolines were ethoxylated by ethylene oxide gas with different ethylene oxide contents (5, 10, and 20) to prepare water soluble stable imidazoline ethoxylates. The chemical structure of the synthesized imidazoline ethoxylates were justified through spectroscopy and surface active properties of the compounds were investigated. The obtained data were discussed on the basis of variation chemical structure. |
