Reactivity of comicelles functional/cationic detergent (functional detergents: 1-cetyl-3-(2-oximino- propyl), 1-cetyl-3-(2-amino-2-oximinoethyl), 1-cetyl-3-(2-oxaminoethyl-2-on) imidazolium chlorides; cationic detergents: 1-cetyl-3-methyl imidazolium and cetyltrimethyl ammonium chlorides) toward 4-nitrophenyl esters of diethylphosphoric, diethylphosphonic and toluenesulfonic acid was studied. It was shown that nucleophilicity of the functional groups in the detergents unaffected significantly with the nature of the head group in the detergent and the proportion of the functional detergent in comicelle. This provides the possibility to design the systems capable of abnormally fast decomposing the organo- phosphoric substrates even at a small concentration of the functional detergent.


Key word functional surfactants, organophosphorous compounds, nucleophilicity, micellar effects.
