Vapor pressures were measured using the static method in the temperature range from 233 to 314 K. The thermodynamic properties for liquid–vapor equilibrium display a linear dependence on number of methylene groups n while the sublimation thermodynamic properties show an evident odd–even effect with higher values for even members of a homologous series. Based on the observed trends, the correlations allowing the prediction of the thermodynamic properties for the crystal–vapor and liquid–vapor equilibria and crystalline and ideal-gas heat capacities within the homologous series are suggested.
