چکیده انگلیسی
Densities, Ï, ultrasonic speeds, u, and viscosities, η of binary mixtures of 2-methyl-2-propanol (2M2P) with acetone (AC), ethyl methyl ketone (EMK) and acetophenone (AP) including those of pure liquids are measured over the entire composition range at temperatures 298.15, 303.15 and 308.15 K respectively. From these experimental data, the excess available volume, VaE, excess free volume, VfE, excess free energy of activation, ÎGâE, deviations in isentropic compressibility, Îks and ultrasonic speed, Îu and excess molar isentropic compressibility, Ks,mE are calculated and reported. The variation of these properties with composition and temperature are discussed in terms of molecular interactions between unlike molecules of the mixtures. Furthermore, the theoretical viscosities have been evaluated using four standard models and the relative merits are discussed.
