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...

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. |
