Die vorliegende Arbeit besteht aus QSPR Studien (quantitative structure property relationship) zur Vorhersage von Schmierfetteigenschaften. Zielsetzung war es Korrelationen zwischen Struktureigenschaften der Schmierfette und deren verschiedensten physikalischen Eigenschaften zu finden und auf dessen Basis ein Modell zur Vorhersage zu entwickeln. Das so entstandene COSMO-LUB (conductor-like screening model-lubricants) Modell kann Verwendung für qualitative und quantitative Aussagen zum Verhalten der Schmierfettsysteme finden und es ermöglichen experimentelle Daten zu inter- und extrapolieren.
This dissertation consists of QSPR studies (quantitative structure property relationship) for the prediction of lubricating grease properties. The aim was to find correlations between the structural properties of the lubricating greases and their various physical properties and to develop a model for predictions based on them. The resulting COSMO-LUB (Conductor-like screening model-lubricants) model can be used for qualitative and quantitative statements on the behavior of the lubricating grease systems and it allows experimental data to be inter- and extrapolated.

This is the only book to apply thermodynamics to real-world process engineering problems. It comprises numerous solved examples, as well as estimation methods for thermophysical properties and phase equilibria, thermodynamics of alternative separation processes, and recent developments. Written for teaching students the engineering perspective of thermodynamics, this is also of interest to all companies active in chemistry, pharmacy, oil and gas processing, petrochemistry, refinery, food production, environmental protection and engineering--
