ABSTRACT

Dielectric constants (a), densities (n), and refractive indices (nD) were measured for binary blend of tetramethylensulfone (TMS) or sulfolane and N-methyldiethanolamine (MDEA) at temperatures ranging from (293.15 to 328.15) K and atmospheric pressure over the whole mole fraction range. From these experimental data, the molar volume (VE), and deviations in refractive indices (AnD), and relative permittivities (Aa), were calculated. These quantities were fitted to the Redlich-Kister polynomial equation to derive the binary adjustable parameters and standard errors. The effective dipole moments of pure liquids were calculated by using of Kirkwood-Frohlich equation.
