Book Description
New experimental data have extended the thermodynamic properties for four completely ionized electrolytes up to 598 K: NaReO4 ( aq), HReO4 (aq), NaCl (aq), and BaCl2 (aq). New thermodynamic data have been obtained for two electrolytes which have not previously been available except at lower temperatures: HCl (aq, completely ionized) and GdCl3 (aq). Finally, such data for four other electrolytes, Co(ReO4)2, Cu(ReO4)2, Na2SO4 and CsCl from unpublished work in this laboratory were recalculated using new computational methods. Corresponding Gibbs free energies were calculated for all of these electrolytes from 298.15 K to 623.15 K. The enthalpy of solution of GdCl3 at 623.15 K and at p [subscript sat] obtained from this research (−2.8 MJ) is apparently larger than any other recorded enthalpy of a chemical reaction on a mole basis. A new theoretical treatment has been developed for predicting the thermodynamic behavior of electrolytes up to the critical temperature of water (and beyond, into superheated steam) and at pressures up to 1000 MPa.

Book Description
Containing the very latest information on all aspects of enthalpy and internal energy as related to fluids, this book brings all the information into one authoritative survey in this well-defined field of chemical thermodynamics. Written by acknowledged experts in their respective fields, each of the 26 chapters covers theory, experimental methods and techniques and results for all types of liquids and vapours. These properties are important in all branches of pure and applied thermodynamics and this vital source is an important contribution to the subject hopefully also providing key pointers for cross-fertilization between sub-areas.

Book Description
Expertise in electrolyte systems has become increasingly important in traditional CPI operations, as well as in oil/gas exploration and production. This book is the source for predicting electrolyte systems behavior, an indispensable "do-it-yourself" guide, with a blueprint for formulating predictive mathematical electrolyte models, recommended tabular values to use in these models, and annotated bibliographies. The final chapter is a general recipe for formulating complete predictive models for electrolytes, along with a series of worked illustrative examples. It can serve as a useful research and application tool for the practicing process engineer, and as a textbook for the chemical engineering student.

Book Description
The objective of this research was to combine new experimental measurements on heat capacities, volumes, and association constants of key compounds with theoretical equations of state and with first principles quantum mechanical calculations to generate predictions of thermodynamic data. The resulting thermodynamic data allow quantitative models of geochemical processes at high temperatures and pressures. Research funded by a DOE grant to Prof. Robert Wood at the University of Delaware involved the development of new theoretical equations of state for aqueous solutions of electrolytes and non-electrolytes, methods to estimate thermodynamic data not available from experiments, collection of data on model compounds through experiments and predictions of properties using ab initio quantum mechanics. During the last three and a half years, with support from our DOE grant, 16 papers have been accepted or published, and 3 more are in preparation. Results of this research have been reported in numerous invited and contributed presentations at national and international meetings. For this report, we will briefly comment on the highlights of the last 3 and a half years and give a complete list of papers published, accepted, or submitted during these years.

Book Description
This book provides a thorough discussion of the thermodynamics of aqueous solutions and presents tools for analyzing and solving scientific and practical problems arising in this area. It also presents methods that can be used to deal with ionic and nonionic aqueous solutions under sub- or supercritical conditions. Illustrations and tables give examples of procedures employed to predict thermodynamic quantities of the solutions, and an appendix summarizing statistical mechanical equations used to describe the systems is also provided. High-Temperature Aqueous Solutions: Thermodynamic Properties contains essential information for physical chemists, geochemists, geophysicists, chemical technicians, and scientists involved in electric power generation.
