Molar enthalpies of solution of 1-pentanol in the AOT/n-heptane system as well as of water in 1-pentanol/n-heptane and in 1-pentanol/AOT/n-heptane systems have been measured at 25/sup 0/C. The results indicate that at infinite dilution, following a Poisson distribution, 1-pentanol molecules distribute between the AOT reversed micelles and the continuous organic phase, whereas at finite concentrations of 1-pentanol, reversed micelles and alcoholic aggregates coexist. It is also found that water added to 1-pentanol/AOT/n-heptane systems is incorporated in both AOT reversed micelles and alcoholic aggregates.
