Resumen: Several thermophysical properties such as densities, p, speeds of sound, u, refractive indices, nD, and kinematic viscosities, v, have been measured for the binary mixtures of N, N-Dimethylacetamide with 1-propanol and 1-butanol over the entire range of composition, at the temperatures (283.15, 298.15 and 313.15) K and at atmospheric pressure p = 0.1 MPa. From these experimental data, excess molar volumes, VE, excess isentropic compressibilities, ?S E , refractive index deviations, ?nD, and viscosity deviations, ??, were calculated. Then, correlated with the Redlich-Kister equation and the corresponding parameters were drived. The results obtained, were discussed in terms of structural effects and specific molecular interactions, and the influence of the alkanol chain length was also considered.
