Measurements and Modeling of Thermodynamic Properties of Binary Systems Comprising (2-Amino-2-methyl-1-propanol with Acetonitrile, Toluene, 1-Pentanol or 1-Hexanol) at Different Temperatures

In this work densities, speeds of sound, and refractive indices of the binary mixtures involving 2-amino-2-methyl-1-propanol (AMP) with acetonitrile, toluene, 1-pentanol, and 1-hexanol were measured at different temperatures, T = (303.15, 313.15 and 323.15) K over the whole composition range (x_AMP = 0-1) and at atmospheric pressure. The derived properties including excess molar volumes, V_m^E, isentropic compressibilities, κ_s, deviation in isentropic compressibilities, Δκ_s, and deviation in refractive indices, Δn_D were calculated from the experimental densities, speeds of sound, and refractive indices and correlated as a function of temperature using the Redlich-Kister polynomial equation. The excess properties of the prepared binary mixtures were found to be positive, negative, or S-shape curves as a function of the composition of x_AMP. The results have been interpreted in terms of molecular interactions and molecular structures occurring between the binary systems.
