Physicochemical characterization of aqueous two phase systems containing Triton X-102 and sodium salts in the range of temperature from 288.15Â k to 318.15Â k

Present work studies the characterization of binary and ternary mixtures based on the use of a surfactant (Triton X-102) and different salts in aqueous solution. All of these ternary mixtures form two different aqueous liquid phases. This characterization consists in the analysis of several physical properties such as refractive index, density and speed of sound. Derivative properties were calculated: excess molar volume and isentropic compressibility. This work analyzes aqueous binary and ternary mixtures (Triton X-102 + salt + water) in the homogeneous zone analyzing the influence of surfactant and salt concentration. Also several phases at equilibrium were characterized. The influence of temperature upon these physical and derivative properties was also analyzed.
