Cationic surfactants of 2-hidroxy-3-(2- alkylamidopolyethyl amino) propane-1-triethylammonium hydroxides (ix-xui)a-d were prepared from fatty acids (i)a-d [palmitic, stearic, oleic, linoleic acid] and mixed fatty acids of crude rice bran oil ie [RBO]. The reaction of these acids with ethylenediamine, diethylenetriamine, triethylenetetramine andletraethylenepentamine (ii)a-d produced (iii-vii)a-d. The produced amidopolyethylamine (iii-vii)a-d reacted with 2-epoxypropylenetriethylammonium chloride (viii) to give the cationic surfactants (ix-xiii)a-d . The produced derivatives were purified and characterized by microanalysis, molecular weight determination, infra-red (IR), and proton nuclear magnetic resonance (1H NMR) spectra. The surface ac...
