Study of Electrical Conductivity of Dilute Solutions of Dicyanamides of N-Alkylpyridinium in Acetonitrile
摘要
Abstract—
Ionic liquids with N-alkylpyridinium cation and dicyanamide anion are synthesized. The structure of the obtained compounds is confirmed by IR spectroscopy data. Studies of the electrical conductivity of dilute solutions in acetonitrile at 25°C are carried out. Based on the conductometric data, using the Lee–Wheaton method, the ionic association constants Ka, the limiting molar electrical conductivity (λ0), and the standard Gibbs energy of association (ΔG0) in acetonitrile solutions are calculated.
