Abstract
The solubility of the ionic liquid (IL) 1-butyl-3-methylimidazolium acetate ([Bmim]Ac) in supercritical carbon dioxide (scCO2) with cosolvents, including ethanol, acetone, dimethyl sulfoxide (DMSO), and acetonitrile, was determined at 40, 50, and 60 °C and with a pressure up to 15.0 MPa. The results showed that the addition of cosolvents has a significant effect on the solubility of [Bmim]Ac in scCO2. The ability of different cosolvents to enhance the solubility of [Bmim]Ac in scCO2 is in the following order: ethanol > DMSO > acetone > acetonitrile. The solubility of [Bmim]Ac in the scCO2/cosolvent mixture increased dramatically as the cosolvent concentration exceeded 20.0 mol %. The effect of the temperature on the solubility is more complicated. The solubility of [Bmim]Ac in scCO2/cosolvent increased slowly when using ethanol as the cosolvent, decreased slowly when using acetone or acetonitrile as the cosolvent, and increased first and then decreased when using DMSO as the cosolvent as the temperature i...
