The research group is engaged in experimental study of equilibria in multicomponent fluid-phase systems and related thermodynamic and thermophysical properties of dilute aqueous and non-aqueous solutions of organic substances. To this end, we employ a large variety of procedures of experimental thermodynamics including phase equilibria measurements (vapor-liquid, liquid-liquid, solid-liquid), calorimetric measurements (enthalpy of mixing, dissolution), volumetric measurements, and measurements of viscosity and optical properties. Currently, we focus mainly on technologically, interesting systems with ionic liquids (IL), deep eutectic solvents (DES) and dilute aqueous solutions of volatile organic compounds (VOC) environmental and sensoric significance. Long-term effort of the group is devoted to experimental method and procedure development. New methods for determination of limiting activity coefficients, selectivity of non-volatile separation agents, mixing enthalpies and solubilities belong to our achievements in this direction.
