Binary and Ternary Phase Equlibria of Supercritical Fluid/Organic/Ionic Liquid Systems
Phase equilibria of supercritical fluid/organic liquid/ionic liquid systems have been measured in a high pressure view cell. Two ionic liquids such as 1-butyl-3-methyl imidazolium hexafluorophosphate (bmimPF6) and 1-butyl-3-methyl imidazolium tetrafluoroborate (bmimBF4) and an organic compound, methanol, have been used. The increase in the amount of organic compound at fixed amount of ionic liquid lowers the LCEP pressure. The K-point pressure was not changed by the type of ionic liquid, the amount of organic compound, or the amount of moisture content.
