摘要

Binary phase equilibria of supercritical CO_2 (scCO_2) and ionic liquid has been measured by Kamps et al. Ternary phase equilibria of supercritical fluid/organic liquid/ionic liquid systems have been measured in the literature. In this research we measured the phase equilibrium of binary and ternary systems using a high pressure view cell. Two ionic liquids such as 1-butyl-3-methyl imidazolium hexafluorophosphate ([bmim][PF_6]) and 1-butyl-3-methyl imidazolium tetrafluoroborate ([bmim][BF_4]) 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.
