Density and viscosity measurements for formamide + methanol (or + ethanol or + 1-propanol) binary systems over the whole concentration range in the temperature range (30 to 50) °C were made. The experimental results were fitted to empirical equations, whose calculated values are in good agreement with the experimental ones. The data of the mixtures were further used to calculate the excess molar volumes and viscosity deviations. These latter results were fitted by the Redlich-Kister polynomial relation to obtain the coefficients and the standard deviations.
