Extraction of bio-butanol from aqueous phase
:

  • Measurements of activity coefficients at infinite dilution,
  • Determination of selectivity and capacity for the butanol/water separation from activity coefficients at infinite dilution,
  • Studies of fundamental thermodynamic functions of ionic liquids, temperature and enthalpy of melting, temperature of glass transition, viscosity, density, surface tension,
  • Studies of phase equilibria in binary and ternary ternary systems with ionic liquids,
  • Determination of selectivity and solute distribution ratio for butanol/water from the measurements of ternary systems {ionicliquid + butanol + water}.
