Abstract

Helmholtz energy equations of state with independent variables of temperature and density were developed for n-perfluorobutane, n-perfluoropentane, and n-perfluorohexane based on experimental thermodynamic property data from the literature and simulation results of this work. The ranges of validity for temperature, pressure, and density of the equations of state for these three fluids were determined from the available data. The uncertainties in density, vapor pressure, saturated liquid and vapor densities, and caloric properties of the equations of state were also estimated from comparisons with the data. The behavior of thermodynamic properties was analyzed to assess the quality of the equations of state; their reasonable behavior can be proven within the range of validity, as well as at high temperatures and pressures, and temperatures far below the triple point temperature.
