Proton Magnetic Resonance Investigations of Alkylammonium Carboxylate Micelles in Non-aqueous Solvents: Part 5.1—Effects of Dodecylammonium Propionate on Solubilizates in Benzene and in Deuterochloroform

Abstract

Chemical shifts, at constant concentration, of the solubilizate protons of dimethyl sulphoxide, imidazole, methanol, pyrazole, and 2-pyridone have been determined as functions of dodecylammonium propionate (DAP) concentrations in benzene, in deuterobenzene, and in deuterochloroform. Equilibrium constants between solubilizates and micellar DAP have been obtained from these data and are discussed. Determined line broadening of both the solubilizate and the DAP protons are discussed in terms of the average lifetime of the solubilizate in the micellar environment.
