摘要：
A study is performed of the electrical conductivity (EC) of ionic liquids based on quaternary triethylalkylammonium salts with tetrafluoroborate and hexafluorophosphate anions in acetonitrile. Conductometric data on these compounds are analyzed. Constants K-a of the ionic association of the limiting molar electrical conductivity (& lambda;(0)) and the standard Gibbs energy of association (& UDelta;G(0)) in solutions are calculated using the Lee-Wheaton formula. The Stokes radii, limiting mobility, and limiting coefficients of diffusion are found for tetraalkylammonium cations.
