Study of Phase Equilibria in Mixtures of Gases, Liquids and Solids
Keywords:
Thermodynamics.
Phase Equilibria: Vapor-Liquid Equilibrium (VLE), Liquid-Liquid
Equilibrium (LLE) and Solid-Liquid Equilibrium (SLE) in Mixtures and
Alloys. Excess Properties: Enthalpy, Volume, Heat Capacity. Theory of
Mixtures and Alloys. Group Contribution Methods: DISQUAC, UNIFAC, ...
Theory of Associated Mixtures.
Topic 1:
Experimental
study of associated mixtures. Molecules containing the oxygen -O- and
the hydroxil -OH groups: Mixtures of alcohols + ethers, and mixtures of
hydroxiethers with hydrocarbons, alcohols and ethers. Mixtures of
molecules containing the amine -NH and the hydroxil -OH groups:
Mixtures of amines + alcohols, ...
Topic 2:
Experimental
study of mixtures with pure dipole interactions. Molecules containing
the oxygen -O- and the ketone -CO- groups: Mixtures of ketones +
ethers; carbonates + hydrocarbons, ethers and ketones, and mixtures of
organic anhydrides with hydrocarbons, ...
Topic 3:
Experimental
and theorical study of mixtures where the excess heat capacity at
constant pressure shows double minima in its composition dependence
(systems where: CPE=CPE(xi) shows
a ω form).
Topic 4:
Application
of theories based in the group contribution concept in order to justify
the thermodynamic properties of liquid mixtures. Systematic application
of the DISQUAC model to explain all kind of mixtures and phase
equilibria.
Topic 5:
Application
of the theories of associated mixtures to explain all thermodynamic
properties and phase equilibria of this type of mixtures. Systematic
application of the ERAS model. Study of Flory theory in order to find
the limitations of the ERAS model.
