Main Topic:

Thermodynamic 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.
