| Description
| - Interactions of volatile organic compounds with two ionic liquids (ILs) 1-butyl-1-methylpyrrolidinium tetracyanoborate [BMPYR][B(CN)4] and 1-butyl-1-methylpyrrolidinium bis(oxalato)borate [BMPYR][BOB] were explored through systematic GLC retention measurements. Infinite dilution activity coefficients (Gamma_inf) and gas?liquid partition coefficients (KL) of 30 selected solutes in both ILs were determined at five temperatures. The Linear Free Energy Relationship (LFER) solvation model was used to correlate successfully the KL values. The LFER correlation parameters and excess thermodynamic functions were analyzed to disclose molecular interactions operating between the ILs and the individual solutes. [BMPYR][B(CN)4] was identified as a very weakly cohesive solvent medium, in contrast to [BMPYR][BOB] which appears to be fairly cohesive IL close in this respect to [BMPYR][DCA] examined recently. Both ILs are capable of interacting specifically through all modes (lone electron pairs, dipolarity/polarizibility, hydrogen bonding) with solutes of complementary capabilities. Their hydrogen bond basicity and ability to interact with lone electron pairs are appreciable but distinctly lower than those of [BMPYR][DCA]. The proton donating capability of these ILs is weak, but still traceable, and stems undoubtedly from unsubstituted hydrogen atoms on the pyrrolidinium ring of their cation. The selectivities of both ILs for separation of aromatic hydrocarbons and thiophene from saturated hydrocarbons rank among [BMPYR] ILs the lowest and medium, respectively. The selectivity of [BMPYR][B(CN)4] is comparable to that of sulfolane, but this IL surpasses it roughly three times in the capacity. Both ILs could also serve as efficient entrainers in separations of other non-petrochemical azeotropic systems of industrial importance by extractive distillation. In particular, we have identified [BMPYR][B(CN)4] as a very convenient separation agent for methanol?dimethyl carbonate mixture.
