Book Description
The transport property which is most fundamentally related to forces between unlike molecules is the ordinary diffusion due to concentration gradients. Unfortunately, this property and its dependence upon temperature have not been systematically studied experimentally, with the result that the literature does not contain the data necessary to obtain good force constants for the introduction of unlike molecuels. The present work describes an experimental method for determining diffusion coefficients, based on the variation of thermal conductivity with composition in binary mixtures which is capable of being used over a wide range of temperature. Experimental results for the systems n-butane-hydrogen, sulfur hexafluoride-hydrogen, argon-hydrogen, and argon-helium are given for a temperature range from 10°C. to 140°C.

Book Description
This classic and bestselling landmark publication, originally published in 1965, examines the dynamic mechanisms, fundamental principles, and physical properties of various chromatographic procedures. It offers methods to characterize, identify, and predict chromatographic phenomena - providing strategies to select the most appropriate separation tools and techniques for specific applications in chemistry, physics, biology, and forensic and environmental science. Written by a world-renowned pioneer in the field, Dynamics of Chromatography contains many worked equations and real-world examples in gas and liquid chromatography. It includes numerous schematic figures for visualization of key concepts, introduces the means to control migration rate differences and zone spreading, and presents a detailed random-walk model for clarification of column processes. It also analyzes flow, diffusion, and kinetic events, stresses the link between theory and practice, and summarizes mathematical quantities and parameters.

Book Description
Must-have reference for processes involving liquids, gases, and mixtures Reap the time-saving, mistake-avoiding benefits enjoyed by thousands of chemical and process design engineers, research scientists, and educators. Properties of Gases and Liquids, Fifth Edition, is an all-inclusive, critical survey of the most reliable estimating methods in use today --now completely rewritten and reorganized by Bruce Poling, John Prausnitz, and John O’Connell to reflect every late-breaking development. You get on-the-spot information for estimating both physical and thermodynamic properties in the absence of experimental data with this property data bank of 600+ compound constants. Bridge the gap between theory and practice with this trusted, irreplaceable, and expert-authored expert guide -- the only book that includes a critical analysis of existing methods as well as hands-on practical recommendations. Areas covered include pure component constants; thermodynamic properties of ideal gases, pure components and mixtures; pressure-volume-temperature relationships; vapor pressures and enthalpies of vaporization of pure fluids; fluid phase equilibria in multicomponent systems; viscosity; thermal conductivity;diffusion coefficients; and surface tension.
