Micellization of some amphiphilic quaternary ammonium chlorides

The micellization processes of N-dodecyl- N,N-dimethyl- N-[3-(β-methyl-β-nitrovinyl)-6-methoxybenzyl] ammonium chloride ( I-A), N-dodecyl- N,N-dimethyl- N-benzylammonium chloride ( I-B), N-dodecyl- N, N,N-trimethylammonium chloride ( I-C), N-dodecyl-[3-(β-methyl-β-nitrovinyl)-4-methoxybenzyl] morpho...

Description
Summary:The micellization processes of N-dodecyl- N,N-dimethyl- N-[3-(β-methyl-β-nitrovinyl)-6-methoxybenzyl] ammonium chloride ( I-A), N-dodecyl- N,N-dimethyl- N-benzylammonium chloride ( I-B), N-dodecyl- N, N,N-trimethylammonium chloride ( I-C), N-dodecyl-[3-(β-methyl-β-nitrovinyl)-4-methoxybenzyl] morpholinium chloride ( IV-A), N-dodecyl- N-benzylmorpholinium chloride ( IV-B), N-dodecyl- N-methylmorpholinium chloride ( IV-C), and N-dodecyl- N-methylpiperidinium chloride ( VI-C) were studied by means of the calorimetric titration method. The critical micelle concentrations and enthalpies of micellization were determined. It is suggested that the benzyl groups of I-B and IV-B and the nitrovinylbenzyl groups of I-A and IV-A behave as second chains during the micellization.
