The thermal properties of cyclopentane were redetermined in the Penn State isothermal calorimeter and adiabatic calorimeter B′ and the results compared with other investigations. It is concluded that the heat capacity results of Penn State adiabatic calorimeter B′, those of the National Bureau of Standards, and those of the Bureau of Mines Laboratory at Bartlesville, Oklahoma, are in satisfactory agreement, under normal operating conditions, above 30°K.

Although experimental vapor pressures are abundant in the medium-pressure range (psat , their values are scarce and uncertain at lower pressures due to experimental difficulties in determining the data. Reliable values are, however, required by technology (separation processes dealing with mixtures containing high molar mass compounds) and environmental concerns (transport and fate of high-boiling pollutants). The ability of frequently used vapor-pressure equations to extrapolate the data at medium pressures toward the triple-point temperature was tested on three groups of compounds (polar and nonpolar organic chemicals, n-alkanes, and 1-alkanols) for which reliable experimental data in the low-pressure range were available. Results of a simple extrapolation were compared with those from a simultaneous correlation of vapor pressures in the medium-pressure range and the differences between heat capacity of an ideal gas and that of the liquid available at lower temperatures. The latter is generally more reliable, as it is controlled by the exact thermodynamic constraints linking vapor pressures and the thermal data. The extent of improvement when using simultaneous correlation was examined, as well as the influence of the quality of input data on the results of extrapolation. Extrapolated values were compared with experimental vapor pressures and calorimetric enthalpies of vaporization that were selected from literature and pee of any important systematic errors. to accurately determine psat at low pressures is of prime importance from an environmental point of view.Reliable vapor-pressure data in the low-pressure range can be used for determining enthalpies of vaporization AHvap of high boiling compounds at 298.15 K, the vaporization data play an important role in various thermochemical and thermodynamic calculations for converting different enthalpic quantities between the gaseous and liquid states.

Equations of state for the xylene isomers (o-xylene, m-xylene, and p-xylene) and ethylbenzene have been developed with the use of the Helmholtz energy as the fundamental property with independent variables of density and temperature. The general uncertainties of the equations of state are 0.5% in vapor pressure above the normal boiling point, and increase as the temperature decreases due to a lack of experimental data. The uncertainties in density range from 0.1% in the liquid region to 1.0% elsewhere (the critical and vaporphase regions). The uncertainties in properties related to energy (such as heat capacity and sound speed) are estimated to be 1.0%. In the critical region, the uncertainties are higher for all properties. The behavior of the equations of state is reasonable within the region of validity and at higher and lower temperatures and pressures. Detailed analyses between the equations and experimental data are reported.
