  • High Pressure Phase Behaviour of Multicomponent Fluid Mixtures

    • 1 Edición
    • R.J. Sadus
    • Inglés
    The high pressure phase behaviour of binary fluid mixtures has been extensively studied during the last three decades. There is ample experimental data for a wide variety of binary mixtures and extensive methods for prediction have been developed. In contrast, the investigation of ternary and other multicomponent fluids is in its infancy. Experimental ternary mixture critical data are very rare and theoretical studies have been limited to data correlation rather than genuine prediction. The phase behaviour of ternary and other multicomponent fluid mixtures has many novel aspects which are not manifested in binary mixtures. The properties of ternary mixtures are also likely to be more difficult to characterize experimentally. It is in this context that calculated phase diagrams have an important role in leading the discovery of new phenomena and guiding experimental work.The criteria for phase equilibria of multicomponent fluids with particular emphasis on the critical state are examined in this book, and models for predicting fluid equilibria (e.g., different equations of state) are compared. Particular attention is paid to the critical state of ternary mixtures which has hitherto been largely neglected. The problems associated with predicting ternary equilibria are discussed, and some novel aspects of ternary critical phenomena are illustrated. The books also describes a novel type of critical transition which appears to be a common feature of the equilibria of ternary mixtures. Extensive phase diagrams of a wide range of ternary mixtures including systems containing carbon dioxide, water, nitrogen and tetrafluoromethane as one or more component are presented. The theoretical treatment is detailed in the appendix and a computation of known experimental critical points is also included.

    • Inglés
    Computer Programs for Chemistry, Volume 4, aims to make available a useful collection of tested programs, which may be expected to have a long useful life. Since the programs in each volume are represented by considerably over 10,000 source cards, arrangements have been made to provide a master tape for each volume. The programs in the series fall into two broad classes: complete packages and subroutines. ANSI FORTRAN has been chosen as the language since it provides adequate flexibility and excellent compatibility. But where departures are needed for efficiency, the editors have not hesitated to allow use of small subroutines in nonstandard FORTRAN or in assembly language, with careful documentation. The programs discussed in this volume include LSKIN2, FRS3, GENLSS, CDORD, EQCENT, EDITQ and EDITID, LORAK, and INDEX. Anyone who intends to use computer techniques will have to learn about computer hardware and computer software. To use effectively even the stand-alone programs in these volumes requires some understanding of FORTRAN. This volume also contains a number of converting subroutines that are useful primarily to the serious programmer. These have proved especially useful as parts of programs presented in previous volumes.

    • Inglés
    The problems related to crazing in polymers are of special interest to polymer scientists since only polymers display this universal phenomenon and no analogues are available for low-molecular-mass compounds. The important problems of solvent crazing and the development of a universal description of polymer structure and properties have received much attention from many leading scientists. Nevertheless, some aspects of polymer crazing are still unclear, and scientific activities in this area are in progress.This work provides an up-to-date account of scientific advances in the area of solvent crazing. The principal features and stages of solvent crazing (craze nucleation, craze tip advance, craze thickening, and craze collapse at high strains) are described. Additionally, the authors present information concerning the activities of Russian scientists in this area, which might have escaped the attention of their colleagues because of the language barrier.

    • B.P. Sullivan + 2 más
    • Inglés
    The recycling of atmospheric molecules for use as fuels and chemicals is a goal which can only be achieved through a deeper understanding of catalytic processes, particularly electrocatalysis whereby redox transformations can be interfaced with solar or nuclear energy input. Carbon dioxide is a prototypical small molecule in many regards since it is chemically inert. In addition, because of the likely role of carbon dioxide in global temperature cycles, it will be imperative in the future to regulate the output from industrial processes. The purpose of this book is to present a unified discussion of the carbon dioxide chemistry which is necessary for the understanding and design of electrochemically-dr... processes for the reduction of carbon dioxide and to provide an impetus for the further development of electrocatalytic carbon dioxide chemistry.

    The Principles of Ion Selective Electrodes and of Membrane Transport is a collection of research works on the theory, principles, and fundamentals of ion-selective electrodes and of membrane transport. This book is organized into two parts encompassing 15 chapters that highlight the application of the membrane model. Part A is a general discussion of membrane potentials and membrane transport. This part describes the formulations of the interfacial potential contribution due to phase boundaries. This part also explores the diffusion potential, the nonideality of diffusion layers or membrane phases, the liquid-junction potential arising in conventional potentiometric measuring cells. Other topics covered in this part include the practical solution for the membrane potential; the ion-transport and the electrical properties of bulk membranes; and the characteristics of lipid bilayer membranes. Part B considers the fundamentals of ion-selective electrodes. This part begins with discussions of the principles, response behavior, ion selectivity, and detection limits of solid-state membrane electrodes. This part also examines several important extensions and modifications of the Sandblom-Eisenman-Wa... theory; the characteristics of neutral carrier membrane electrodes; and the theory of glass electrodes.

    The Organic Chemistry of Palladium
    • 1 Edición
    • Peter Maitlis
    • Inglés
    The Organic Chemistry of Palladium, Volume 1: Metal Complexes deals with the number of organic reactions that can be catalyzed by palladium, particularly as regards the structures bonding, and reactions of the metal complexes. The book discusses monodentate ligands which are either neutral (carbonyls, isonitriles, carbenes) or anionic (methyl, phenyl, ethynyl, hydride). The text also examines the complexes formed by 1,3-. 1,4-, and 1,5-diolefins where four carbon atoms are bound to the metal. Palladium (II) can undergo a reaction with the 1,3-dienes and results in a ?-allylic complexes where only three carbon atoms are coordinated to the metal. (The bonding situation in complexes 1,4- and 1,5-dienes, where no great interaction between the olefins are similar to that in monoolefin complexes, is straightforward), Olefins can also react with palladium chloride in protic solvents to produce ketones (or aldehydes) or organic coupling products. Some experiments conducted by Huttel et al shows that some palladium was precipitated from the reactions giving lower yields, resulting in various aldehydes and ketones as by products. The book also discusses cyclopentadienyl and benzene complexes. The text can prove beneficial for researchers, investigators and scientists whose works involve organic chemistry, analytical chemistry, physical chemistry and inorganic chemistry.
