Accurate experimental measurements of thermodynamic and transport properties of fluids, such as phase equilibria (V-L, S-V-L,L-LV, etc...), critical points, viscosities, solubilities, recristalization by supercritical antisolvent, volumetric and excess properties, are required for the fundamental study of binary and multicomponent mixtures behavior. These are also needed for designing, optimization and simulation of industrial processes.

In Mexico, this is the first thermodynamic research laboratory applied to accurate experimental determination of thermodynamic and transport fluid properties of fluids, solids and his mixtures up to 100 MPa and 673 K.

In this communication is presented the research fields and their obtained result in the Thermodynamics laboratory:

· Development of equations of state derived from classic thermodynamics and statistical mechanics.

· Development of new apparatus for measure thermodynamic properties of pure fluids, binary and multicomponent mixtures. Experimental data of phase equilibria and volumetric properties of CO 2 +Alkanes, CO 2 +Alkanols, H 2 O+Alkanols, CO 2 +Alkanols+Alkanes, H 2 O+Alkanes y CO 2 +Alkanols+H 2 O mixtures up to 60 MPa and 523 K.

· Solubilities of solids and solid mixtures in supercritical solvents

· Solubilities, phase equilibria and uses as cosolvent of Ionic Liquids (IL), IL+CO2, IL+CO2+alkanols, IL+CO2+Alkanols+Sulfur compounds and IL+CO2+Sulfur Compounds.

· Development of supercritical fluids processes of extraction in biotechnology, chemistry, food and petroleum areas.

· Molecular Simulation. The objective is to have a support from the molecular point of view of the experimental thermodynamic and transport properties measurements and eventually to understand the superconductivity of fluids.
