Solubility of solids in near-critical fluids II. CHI3and CI4in ethene

The solubilities of CHI3(s) and CI4(s) in near-critical fluid C2H4have been spectrophoto-metrically determined. Isothermal solubility measurements were carried out under subcritical conditions in the dense phase at temperature (273.13±0.01) K for CHI3and (274.47±0.01) K for CI4, and under supercriti...
