ELECTRICAL CONDUCTIVITY AND ASSOCIATION OF TRIHEXYLTETRADECYLPHONIUM BROMIDE IN DIMETHYLFORMAMIDE
In the temperature range 20 - 85 °C, the specific electric conductivity of dilute solutions of trihexyltetradecylphosphonium bromide in dimethylformamide (DMF) was measured. According to conductometric measurements using the Li-Wheaton equation, the thermodynamic parameters of the association are calculated. It was found that with increasing temperature the ionic association of the investigated ionic liquid is enhanced, and the specific electric conductivity increases in direct proportion to the value of the limiting high-frequency conductivity of the solvent.
