Abstract

Solid solubilities of naphthalene and biphenyl in supercritical carbon dioxide were measured at various Isotherms above 31.06 °C—the critical temperature of CO₂—and over a range of pressures from 80 to 500 atm. The upper critical end point for the naphthalene-carbon dioxide system Is estimated from the solubility data to be 63 °C, 240 atm, and a naphthalene mole fraction of 0.16. The upper critical end-point temperature for the biphenyl-carbon dioxide system Is ˜56 °C and at a pressure near 460 atm. The biphenyl mole fraction at the upper critical end point (UCEP) Is ˜0.1.6.
