Физико-химические свойства водных растворов некоторых ионных жидкостей

Abstract

Using the method of computer resistometry, certain physicochemical properties of aqueous solutions of a group of proton ionic liquids in an equilibrium state were determined – electrical conductivity, dissociation parameters, pH, and their concentration functions. For measurements, a pulsed low-frequency NRK conductmeter-resistmeter, a series of special sensors for working with macro- and micro-volumes (up to 50 mm3) of solutions sensitive in a wide concentration range up to 1 M were developed. Correlations were established between the physicochemical properties of aqueous-organic mixtures and the possible structure of the organic phase.
