ABSTRACT

The density (n), speed of sound (u), and refractive index (nD) of amino acid ionic liquid surfactants (AAILSs) prepared from natural amino acids, L-glycine, L-alanine, L-valine, L-glutamic acid, and L-proline, and sodium lauryl sulfate have been measured in the temperature range from (288.15 to 343.15) K. The temperature dependence of density has been used to calculate the coefficient of thermal expansion (a). Using the experimental n and u values, the isentropic compressibility (es) has been calculated for various AAILSs. The molar refraction (RM) has been calculated from experimental nD values in the temperature range from (288.15 to 343.15) K. Refractive indices of ILs were found higher than those of normal organic liquids but are comparable to long hydrocarbon chain organic solvents.
