Description
Abstract:	Acetophenone and benzophenone are solubilized by micellar hexadecyltrimethylammonium bromide (CTAB), hexadecylpyridinium chloride (CPyCl), sodium dodecyl sulfate (NaLS), 3-(dimethyldodecylcammonio)propane-l-sulfonate (DDAPS), and polyoxyethylene (15) nonylphenol (Igepa; Co-730). The solubilization site and the nature of this environment depend upon the solubilizate, the surfactant, and the extent of water penetration into the micelle. Marked differences in solubilization among these phenones by the different surfactants suggest some dependence on the character of the head groups of CTAB and DDAPS. ¹H nmr spectroscopy shows considerable differences in the resonance frequencies of the terminal methyl (CH₃ (CH₂)(subscript n)) and methylene (CH₃ (CH₂)(subscript n)) protons as well as those of the surfactant head group and substrate protons upon solubilization of acetophenone and benzophenone. The probable solubilization sites and orientation of the substrate molecule within the various micelles are discussed in terms of these experimental parameters.
