Thermophysical properties of 2,2,2-trifluoroethanol + tetraethylene glycol dimethyl ether
- Univ. Rovira i Virgili, Tarragona (Spain). Dept. of Mechanical Engineering
Isothermal P,x data from 303.15 K to 423.15 K, liquid densities from 283.15 K to 423.15 K, and dynamic viscosities from 343.15 K to 393.15 K for the binary system 2,2,2-trifluoroethanol + tetraethylene glycol dimethyl ether were measured. The vapor-liquid equilibrium (VLE) data were measured. The vapor-liquid equilibrium (VLE) data were measured using a static apparatus. VLE data were correlated by the five-parameter NRTL equation, while density and kinematic viscosity data were correlated with temperature and liquid composition using empirical equations. The viscosity data used in the correlation cover the range of 293.15--393.15 K. VLE data indicate that this binary system exhibits large negative deviations from Raoult`s law. These mixtures present large exothermic excess molar enthalpies. The excess molar enthalpy calculated using the Gibbs-Helmholtz equation and the NRTL parameters was compared with experimental data existing in the literature.
