✦ Synopsis

The solubilities of CHI3(s) in supercritical C2H6 and CO2 have been determined spectrophotometrically close to the solvents' critical points at temperatures of 312.90 K and 327.00 K in C2H6, and 312.73 K and 326.95 K in CO2, over a range of fluid densities. Isothermal solubilities show the sharp change with pressure characteristic of near-critical behaviour. Solubilities are almost twice as large in CO2 than in C2H6 over the whole reduced density range. Enhancement factors E were calculated and compared to those of CHI3(s) in C2H4, CHF3, and SF6. The differences observed in E correlate well with the charge distribution, and hence multi-pole moments, of the solvent molecules.
