Abstract

The density and ultrasonic studies of the surfactant-crown ether inclusion complexes has been carried out in the presence of different fixed concentrations of crown ether in order to study the host-guest encapsulation, if any, and the resultant change in the apparent behavior of the inclusion complexes. The apparent and transfer properties including the apparent molal volume VΦ, s, isentropic compressibility K Φ, s, have been deduced from the experimental data. The infinite dilution values of VΦ, s, and K Φ, s, of the solvated species are also estimated by extrapolation towards infinite dilution. The resulting parameters allow the observation of concomitant reorganizations occurring in the system. Results of density and ultrasonic velocity behavior of the inclusion complexes show that there is an overall increase in compressibility of the studied systems.
