Determination of the solubility parameter of ionic liquid 1-octyl-3-methylimidazolium hexafluorophosphate by inverse gas chromatography

The specific retention volumes of the probes:■ n-C6; ● n-C7; ▲ n-C8; ▼ n-C9; ◄ benzene; ► toluene; ◆ m-xylene; ★cyclohexane on the [OMIM]PF6, Vg0, obtained experimentally from the IGC measurements between 343.15 K and 373.15 K, the values of InVg0 decrease linearly with the temperature from 343.15 K to 373.15 K.
