Název v původním jazyce

Interactions of volatile organic compounds with the ionic liquids 1-butyl-1-methylpyrrolidinium tetracyanoborate and 1-butyl-1-methylpyrrolidinium bis(oxalato)borate

Popis výsledku v původním jazyce

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, dipol
