摘要
The high-pressure electric conductivity cell was newly developed for in-situ observations in multi-phasic solution systems. The conductivity of 1-butyl-3-methylimidazolium hexafluorophosphate ionic liquid in contact with CO2 was determined at 40 C as a function of CO2 pressure up to similar to40 MPa. The conductivity of the ionic liquid exhibited a remarkable increase due to the dissolution of CO2 in the pressure range of 0.1 - 10 MPa.
