ELECTRICAL CONDUCTIVITY OF SOLUTIONS OF IONIC LIQUIDS BASED ON 1-ALKYL-2-METHYLPYRIDINIUM SALTS WITH INORGANIC ANIONS IN ACETONITRILE

Авторами работы получены ионные жидкости с катионом 1-алкил-2-метилпиридиния и неорганическими анионами. Проведены исследования электропроводности их растворов в ацетонитриле. Методом Ли-Уитона рассчитаны константы ионной ассоциации K, предельная молярная электрическая проводимости (λ) и энергия Гиббса ассоциации (ΔG) в растворах. The authors of the work obtained ionic liquids with 1-alkyl-2-methylpiridinium cation and inorganic anions. Studies of the electrical conductivity of their solutions in acetonitrile have been carried out. The Li-Wheaton method was used to calculate the ion association constants K, the limiting molar electrical conductivity (λ), and the Gibbs association energy (ΔG) in solutions.

Preparation of Some Novel Copper(I) Complexes and their Molar Conductances in Organic Solvents

Attempts have been made to prepare some novel copper(I) nitrate, sulfate, and perchlorate complexes. Molar conductances of these complexes have been measured in organic solvents like acetonitrile (AN), acetone (AC), methanol (MeOH), N,N-dimethylformamide (DMF), N,Ndimethylacetamide (DMA), and dimethylsulfoxide (DMSO) at 298 K. The molar conductance data have been analyzed to obtain limiting molar conductances (λ0) and ion association constants (KA) of the electrolytes. The results showed that all these complexes are strong electrolytes in all organic solvents. The limiting ionic molar conductances (λo± ) for various ions have been calculated using Bu4NBPh4 as reference electrolyte. The actual radii for copper(I) complex ions are very large and different in different solvents and indicate some solvation effects in each solvent system
