摘要: Abstract The degree of solubilization for all combinations 6 surfactants (sodium dodecanoate, sodium dodecyl sulfate, octylbenzene sulfonate, phenylundecanoate, dodecyltrimethylammonium bromide, and dodecylhexaethyleneglycolmonoether) 12 solubilizates (1-pentanol, 2-pentanol, 3-pentanol, tert-pentanol, methyl-n-propyl ketone, diethyl benzene, benzyl alcohol, crown 18-6, 12-4, 1,4-dioxane, ethyl glycol) have been determined at a surfactant concentration 50 mg/ml D 2 O solution low total solubilizate/surfactant ratios. most striking observations concern the behavior nonionic surfactant; with aliphatic type it weakly, aromatics as strongly other surfactants, ethers hardly all. With exception that bromide micelles solubilize ketones more weakly in relative sense, remaining five exhibit very similar characteristics. NMR-based evidence regard to site is discussed.
