Solubilities of Iodobenzene, Phenylboric acid, Biphenyl and 4-Phenyltoluene in Carbon Dioxide with the Measurements of the relative Permittivity

Solubility data were obtained for the first time for phenylboric acid, iodobenzene, and biphenyl in carbon dioxide at (353 and 383) K and between pressures of (100 to 300) bar. Data were obtained using a method that used the relative permittivity of the binary mixture. The technique was verified by comparison of solubility data for 4-phenyltoluene that had been determined previously by ourselves using a cloud point technique. The relative permittivity for CO2 was also determined at (353 and 383) K between pressures of (100 to 300) bar.
