The dependence of limiting amounts of solubilized water upon the concentration of sodium 1,2-bis(2-ethylhexyloxycarbonyl)ethanesulfonate (AOT) in apolar solvents was measured by the Karl-Fischer method at 30 °C. In the solubilization regions, two or three states of water, i.e., water bound directly to ionic head groups of AOT and water bound to the hydrated ionic groups or bulk-like water, were found to exist from NMR, ESR, fluorescence, and near infrared spectroscopic measurements. These types of water were related to the formation of reversed and swollen micelles or W/O microemulsions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
