| Abstract: |
Solubility data of carbon dioxide, propane, propylene, n-butane, and 1-butene in the ionic liquid 1-n-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([bmim][Tf2N]) are presented as a function of pressure at temperatures between 280 K and 340 K. The equilibrium pressure at a given temperature and the amount of gas dissolved into the ionic liquid phase were measured with an experimental technique based on a saturation method at constant volume using an apparatus equipped with a cylindrical equilibrium view cell. 1-Butene had the highest solubility, followed by n-butane, propylene, and then propane. Carbon dioxide and propane are similarly the least soluble in the [bmim][Tf2N]. Alkene gases were more soluble than alkane gases. The Henry's constants of each gas in the ionic liquid were estimated as a function of temperature from the experimental solubility data. |
