Abstract : The solubility of phenanthrene in gaseous ethylene, ethane, methane, carbon dioxide and carbon tetrafluoride in the pressure range of 2000 to 8000 psi at 40C was determined experimentally. It was found that the solubility as a function of pressure changes nonlinearly for C2H4, C2H6 and CO2, the incremental solubility decreasing with increasing pressure. The dissolving power of the various gases tends to be in the following order: C2H4> C2H6> CO2> CH4> CF4. A static equilibrium arrangement was used. The saturated gaseous phase was analyzed for its content of phenanthrene by decompressing from equilibrium pressure, capturing the precipitated solid by a condensation trap, measuring the expanded gas volume at atmospheric pressure and room temperature, and weighingthe precipitated solid directly. Mercury served as the compressing fluid; its solubility in the gases was considered to be negligible under the conditions of the experiments. (Author)
