Heats of vaporization and some other related thermodynamic quantities were determined for the four alkylcycloparaffins: ethylcyclopentane, n-butylcyclopentane, ethylcyclohexane and tert-butylcyclohexane. The temperature dependence of heats of vaporization was measured and employed for calculating standard heats of vaporization, internal and cohesive energies of vaporization, entropies of vaporization, and differences between heat capacities of liquids and vapours at constant pressure and along the saturation line of vapours.
