The present paper reports the experimental data for density, rho, viscosity, eta, and speeds of sound, u for the binary mixtures of 2-propanol, (CH3)(2)CHOH with hexadecane, C16H34 over the miscibility region (0 < x(1) < 1) and with squalane (2,4,6,10,15,19,23-hexametyltetracosane), C30H62 over the miscibility region (0 < x(1) < 0.6) at T = (298.15, 303.15, and 308.15) K. The experimental data have been used to calculate various parameters like excess molar volumes, V-m(E), viscosity deviations, Delta eta, excess molar isentropic compressibility, K-S,m(E), and deviations in speed of sound, u(D), from their ideal values u(id). These excess parameters and deviations are used to interpret the molecular interactions in these binary mixtures. (C) 2008 Elsevier Ltd. All rights reserved.
