Thermodynamic properties of five halogenated hydrocarbons, of importance as working fluids for small vapour power units, have been studied. The compounds are monochlorobenzene, hexafluorobenzene, o-dichlorobenzene, perfluoro-2-butyltetrahydrofuran and perfluorodecalin. With the aid of the Martin-Hou equation of state the properties of each compound, including sonic velocities and specific heat ratios, have been correlated. By comparison with the well established data for steam the accuracy of the sonic velocity and specific heat ratio values has been indicated. The information is presented in a manner which facilitates either the production of saturation and superheat tables or diagrams, or direct inclusion of the data in computer design and simulation studies of Rankine plant.
