Partitioning Behavior

An aqueous two-phase system (ATPS) was presented with hydrophilic ionic liquid 1-Butyl-3-methylimid-azolium tetrafluoroborate ([BmiBF4) and salts for the extraction of penicillin G in this paper. The phase forming abilities of different salts were investigated to choose a suitable salt.The partitioning behavior of penicillin G in the ATPS was investigated.Concentrations of (NH4)2SO4, penicillin G, and [BmiBF4 were evaluated to determine their effects on the extraction yield of penicillin G. It was found that extraction yield strongly depended on the concentration of [BmiBF4, penicillin and (NH4)2SO4. A high extraction yield around 93% was achieved with the following parameters: (NH4)2SO4 20% (wt%), penicillin 40000 ~ 45000 U/mL, [BmiBF4 20% (wt%).

AbstractIn this paper, an ionic liquid-based aqueous two-phase system (ILATPS) was applied to the chiral separation of α-cyclohexylmandelic acid (α-CHMA) enantiomers with hydroxypropyl-β- cyclodextrin (HP-β-CD) as the chiral selector. Several influencing parameters were investigated including the types and concentration of ionic liquids, the amount of phase-forming salt, temperature, mixing time, pH, and the content of HP-β-CD. The results showed that not all ILATPS had the ability to chirally recognise the selected enantiomers and that [C
