Densities for binary mixtures of cyclopentane with 1-propanol, 1-pentanol, and 1-heptanol over the whole composition range have been measured at temperature 318.15 K. From these densities, excess molar volumes were calculated. All the experimental excess molar volumes were fitted to Redlich–Kister equation and were analyzed with the help of Prigogine–Flory–Patterson theory. Also isobaric expansibilities and their excess counterparts were calculated. Further different approaches were analysed for calculating ideal expansibilities.
