Ken Marsh joined the department in 1997 after 11 years as Director of the Thermodynamics Research Center at Texas AandM University, College Station, Texas where he was responsible for the publication of the TRC Thermodynamic Tables (a major source of evaluated thermophysical property data on organic compounds), TRC Spectral Data, and International Data Series, Series A along with a variety of electronic databases for accessing thermophysical property data. In addition he held Professorial appointments in the Departments of Chemical Engineering and Chemistry and taught graduate courses in thermodynamics and applied statistical thermodynamics and was involved in the measurement of property data including enthalpy, vapour-liquid equilibria, and density as a function of pressure and temperature for new refrigerants, refrigerant mixtures, and mixtures of gases important to the natural gas industry. Prior to that he was an Associate Professor in the Department of Chemistry at the University of New England, NSW, Australia where he was involved in the development of new experimental techniques for the measurements of the thermophysical properties of mixtures and the application of equations of state for prediction of mixture properties. He is currently Editor of the Journal of Chemical and Engineering Data published by the American Chemical Society. In 1969 he was awarded the Nuffield Dominion Travelling Fellowship for advanced study in United Kingdom and in 1972 he was awarded the Rennie Memorial Medal by the Royal Australian Chemical Institute for the most significant contribution to research by an Australian chemist under the age of 32. He was awarded TEES Fellowships in 1985, 1986, and 1987 and a Senior TEES Fellow in 1988 by the Texas Engineering Experiment Station for significant contributions to research. In 1996 he was awarded an Honorary Medal by the Institute of Physical Chemistry, Polish Academy of Science, for significant contribution to the advancement of Physical Chemistry at the Polish Academy of Science.
Measurement of Thermodynamic Properties of Fluids and Fluid Mixtures
Present chlorofluorocarbon refrigerants need to be replaced by environmentally benign refrigerants based on fluorocarbons. Properties such as density as a function of pressure and temperature, vapour pressure, and critical properties of candidate pure fluids or mixtures need to be measured both as pure fluids or as mixtures with lubricants. Aqueous solutions of alkanolamines are used to remove acid gases such as carbon dioxide and hydrogen sulphide from natural gas. To design efficient separating systems vapour liquid equilibria, heats of mixing and equilibria data need to be measured over a wide range of temperature and pressure. Room temperature ionic liquids are salts that are liquid at room temperature. They show unusual properties and are being considered as replacements for volatile organic solvents. Properties of both the pure compound and mixtures with organic compounds are under study.
Prediction of Properties of Organic Compounds and Mixtures
Various prediction methods have been developed based on limited data sets. With access to large databases it is now possible to reassess these methods and develop improved predictions based on detailed structural information on the molecules.
