The vapor pressures of three binary systems, (ethyl hexanoate (1) + n-tetradecane (2)), (ethyl decanoate (1) + n-tetradecane (2)), and (ethyl tetradecanoate (1) + n-tetradecane (2)), were measured by means of a static apparatus at temperatures between (373.15 and 453.15) K. We correlated the data with the Antoine equation. The molar excess Gibbs energies G(E) obtained from these data by using Barker's method were fitted to the Redlich-Kister equation. A maximum azeotropic behavior is observed for the binary mixture {ethyl decanoate (I) + n-tetradecane (2)}. Positive values of the excess Gibbs energy are obtained for all of the investigated temperatures and compositions. The data were also correlated by using Wilson equation. The predicted G(E) obtained by using group contribution model, UNIFAC (Gmehling version), are different to the experimental values. These deviations are more important for systems {ethyl decanoate (1) + n-tetradecane (2)} and {ethyl tetradecanoate (1) + n-tetradecane (2)}.
