Vapor pressure and liquid heat capacity of perhydroacenaphthylene and perhydrophenanthrene

Saturated vapor pressures and liquid heat capacities have been measured for liquid perhydroacenaphthylene and perhydrophenanthrene by comparative ebulliometry 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 equations and by an empirical polynomial equation, respectively, and compared with the data available in the literature.
