Giant Molecules - Supplementary Reading - Index - Preface - When Dr. Frank C. Whitmore was president of the American Chemical Society in 1938 and made the customary tour of local ACS sections, he used that occasion to spread the gospel of the electron theory of valence. At one of his lectures the author of this book sat in the audience among a mixed group of chemists consisting of technicians, students, and college graduates. The lack of familiarity of organic chemists with the electron was so obvious that it aroused in the author an urge to write an elementary introduction to organic chemistry in which the role of the electron would be emphasized. This book is especially intended to serve two groups of readers: those engaged in work of a chemical nature who are not able to take a classroom course in organic chemistry, and those in a college course who find they have a need for a supplementary book to help clarify the approach to modern organic chemistry. In other words, the book was conceived as an integrated introduction to both electron-valence theory and organic chemistry at a level suitable for self-study. The first edition of this book appeared in 1943 during World War II. A second edition, much enlarged, was published in 1955. For this third edition the book has been extensively rewritten, and more than enough material has been added so that it can serve as a textbook for a one-year college course. The novel arrangement of the subject matter in the earlier editions has been maintained. A teacher who prefers to lecture largely from his own notes should find no difficulty incorporating his material into the simple plan on which this book is based.

Studies in catalyst deactivation play a major role in the identification of the real catalytic system, in particular, the structure and texture of the solid, which is often in a metastable state, as it is operated in the industrial reactor. These studies also allow the identification of the experimental conditions which preserve this active and selective state. This is crucial for a real understanding of catalysts and catalysis. Another area of catalytic science concerns reactions kinetics, which, if properly determined, are of paramount importance in the elucidation of mechanisms. The behavior of the kinetics during aging and deactivation and an accurate modeling of the evolution of activity and selectivity are essential information for the process performance. These are just two typical examples, but quite generally, the science of catalyst deactivation is going to be more oriented to fundamental issues.

This book presents a theoretical analysis of the modern methods used for modeling various chemical engineering processes. Currently, the two primary problems in the chemical industry are the optimal design of new devices and the optimal control of active processes. Both of these problems are often solved by developing new methods of modeling. These methods for modeling specific processes may be different, but in all cases, they bring the mathematical description closer to the real processes by using appropriate experimental data. In this book, the authors detail a new approach for the modeling of chemical processes in column apparatuses. Further, they describe the types of neural networks that have been shown to be effective in solving important chemical engineering problems. Readers are also presented with mathematical models of integrated bioethanol supply chains (IBSC) that achieve improved economic and environmental sustainability. The integration of energy and mass processes is one of the most powerful tools for creating sustainable and energy efficient production systems. This book defines the main approaches for the thermal integration of periodic processes, direct and indirect, and the recent integration of small-scale solar thermal dryers with phase change materials as energy accumulators. An exciting overview of new approaches for the modeling of chemical engineering processes, this book serves as a guide for the important innovations being made in theoretical chemical engineering.
