Electrochemical studies on the modular podand 1,3,5-tris(3-((ferrocenylmethyl)amino)pyridiniumyl)-2,4,6-triethylbenzene hexafluorophospahte in conventional solvents in ionic liquids

Article Abstract:

The solution-phase voltammetry of the modular podand 1,3,5-tris(3-((ferrocenylmethyl)amino)pyridiniumyl)-2,4,6-triethylbenzene hexafluorophospahte, [Pd][PF6](sub 3), in acetonitrile and ionic liquids exhibited a well-defined diffusion-controlled process at a potential of about 1.40 V vs [Co(Nu5-C5H5)(sub 2)](super +/0). The voltammetry of very slowly dissolving microparticles of [Pd][PF6](sub 3) mechanically attached to an electrode surface in contact with ionic liquids was indistinguishable from that observed when the podand was in the dissolved state in the ionic liquid.

Deviations from ideality in mixtures of two ionic liquids containing a common ion

Article Abstract:

Excess molar volumes of six binary mixtures composed of two ionic liquids of the 1-methyl-3-alkyl-imidazolium bis(trifluoromethylsulfonyl)amide family-([C(sub m)mim] + [C(sub n)mim])[NTf(sub 2)] with n and m ranging from 2 to 10 were measured for several compositions at 298 and 333 K. Also, three other systems containing [C4mim](super +) (1-methyl-3-butylimidazolium) as a common cation were studied.

Determination of the entropy of ion transfer between two immiscible liquids using water/oil/water thermocouple

Article Abstract:

The standard entropy of ion transfer is determined by using a nonisothermal galvanic cell. It is shown that the water/oil/water thermocouple can be utilized for determining accurate values of the standard entropy for various ions.
