Saturated vapor pressures and liquid heat capacities have been measured for
liquid perhydroacenaphthylene and perhydrophenanthrene by comparative ebul
liometry over an approximate pressure range from (8 to 100) kPa and by heat
conduction calorimetry over a temperature range from about (305 to 335) K.
The obtained results for vapor pressures and for heat capacities have been
represented within experimental uncertainties by the Antoine and the Cox e
quations and by an empirical polynomial equation, respectively, and compare
d with the data available in the literature.
