Annotation -
The estimation methods and theoretical predictions of physicochemical properties show a rapid development as documented by a high number of scientific papers published on the subject in recent years. This is due to an enormous increase in the number of newly synthesized chemicals for which the basic physicochemical properties required in a variety of applications and processes are not available. During the course, PhD students will get oriented in a high number of published estimation methods and acquire knowledge on applying various types of predictive models. Emphasis is placed on the use of quantum chemistry and statistical thermodynamics methods in areas where these methodologies provide results with uncertainty comparable to experimental uncertainty, such as the calculation of gas-phase thermochemical properties or modeling of thermodynamic properties of crystals. Furthermore, methods based on a group contribution concept, quantitative structure-property relationship methods and methods used for prediction of physicochemical data for multicomponent complex mixtures are discussed. In the frame of the course, PhD students will elaborate and defend a project on the prediction of physicochemical quantities for selected systems.
