• Description of solid-liquid and vapour-liquid phase equilibrium curve for organic and organometallic compounds (experimental determination of vapour pressure, simultaneous correlation of vapour pressure and of related thermal properties). Details.

 

• Calorimetric determination of heat capacities and of phase change enthalpies. Heat capacity of liquids: compilation, correlation, and prediction (database of experimental heat capacities of liquids, database of critically evaluated data, group contribution method). Enthalpy of vaporization: compilation, prediction.

Equipment

Static Apparatuses for Vapour Pressure Measurement

Several versions of static apparatuses were designed and constructed in our group.  The apparatuses internally denoted as STAT3, STAT6 and STAT7 are currently in use. The construction of STAT8 is in progress. All the apparatuses are fully automated.
