Third phase formation in the extraction of HCl by tri‐n‐butyl phosphate (TBP) in n‐octane has been investigated. The extraction of the acid is accompanied by the simultaneous extraction of large amounts of water and brings about organic phase s

The predominant mode of strontium ion transfer from aqueous nitrate media into a series of 1-fluoroalkyl-3-methylimidazolium bis[(trifluoromethylsulfonyl)]imides containing dicyclohexano-18-crown-6 (DCH18C6) is shown to shift from cation exchange to

Addition of an appropriate concentration of water to either 1-decyl-3-methylimidazolium bromide or its nitrate analog is shown to trigger the self-assembly of the ionic liquid (IL) and the concomitant formation of gel (“ionogel”) phases adopting
