Densities and viscosities of the binary mixtures of diethyl carbonate (DEC) with 1-propanol, 1-butanol, and 1-pentanol have been determined at (293.15 to 363.15) K and at atmospheric pressure. Excess molar volumes and viscosity deviations for the binary mixtures were fitted to the Redlich-Kister equation. Dependences of excess molar volumes and viscosity deviations with carbon chain length were discussed. The UNIFAC-VISCO method, based on contribution groups, has been used to calculate the dynamic viscosities of the binary mixtures. The percentage deviations between experimental and predicted values are given.
