  Membrane transport experiments into Dichloromethane (DCM) and o-Dichlorobenzene (oDCBz) were performed at 298 K using basic mixtures of NaCl, picrate ion, and crown compounds (L). Here, L shows 15-crown-5 ether (15C5), benzo-15C5 (B15C5), 18-crown-6 ether (18C6), or B18C6. A used cell was (-) ref. electrode|0.05 mol/L (C4H9)4NCl|org (=DCM or oDCBz) |mixture| ref. electrode (+), where the ref. electrode is a commercial one composed of 3 mol/L NaCl|AgCl|Ag. First-order rate constants (k/minute–1) and a parameter, fΔE’, with potential differences ΔE’/V at the (C4H9)4NClaq|org interfaces and f=F/RT, were determined. The natural logarithm of the apparent distribution constant (KD’) defined before for the ion transfer into the organic phases was displaced by this parame.. View more»
