Download or read book Frontiers of Free Radical Chemistry written by William Pryor and published by Elsevier. This book was released on 2012-12-02 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Frontiers of Free Radical Chemistry covers the proceedings of the 1979 symposium on Frontiers of Free Radical Chemistry, held in Louisiana State University Chemistry Department, supported by the Exxon Education Foundation. The contributors discuss the mechanisms of hydrocarbon cracking; oxidation processes; inhibition; and the theory of organic radical reactions, halogenations, and organic peroxide chemistry. This book is organized into three parts encompassing 15 chapters. Part I deals with the understanding of molecular and free radical mechanisms in predicting thermochemical data for radicals and molecules. This part also describes the relationship between distortions of organic molecules and the reactions of pericyclic, ionic, and radical molecules. Part II presents quantitative evaluations of gas phase reactions or carbynes and hydrocarbon pyrolysis and cracking. Discussions on the reactions of free atoms and radicals in the chemistry of the stratosphere and natural troposphere, with an emphasis on the ozone layer and its potential depletion by artificial pollutants, are included in this part. Part III explores the pertinent free radical reactions related to fuel research. Petroleum chemists, researchers, and engineers will find this book invaluable.

Available in PDF, EPUB and Kindle. Book excerpt: This book subtitled The Chemistry of Initiation of Non-Ringed Compounds/Monomers is the second Volume [Vol. (II)] of the book titled The New Frontiers in Sciences, Engineering and the Arts. For a compound to undergo Initiation, it must be such that has what is called Activation center(s) wherein there are three kinds of many types. When such compounds are activated, they can be made to undergo either polymeric or chemical reactions. When made to undergo polymeric reactions, the compounds are said to be Addition monomers. It is only when the Initiation Step is favoured by the monomer using an Initiator, that the Propagation Step begins, just as when a child is born into our world, the child begins to grow. If the Initiation Step is not favoured, due to presence of what are called Transfer Species, then chemical reactions take place to give non-polymeric products under Equilibrium mechanism conditions. There are different kinds and types of Transfer Species. They are so important to the point where they indeed embrace the first law in Chemistry, that which has been called The law of Conservation of transfer of transfer species, almost analogous to the Conservation laws in Engineering. Based on this law, so many new concepts too countless to list were identified. How some compounds/monomers rearrange to give other compounds/monomers via different kinds of phenomena all new to Present-day Science, have been identified. So also, are the concepts of Resonance Stabilization which was thought to take place chargedly, something very impossible. There are also many monomers which Present-day Science activate chargedly, things all found to be impossible. Indeed, as has been said, all chemical reactions take place only radically, while only some polymeric reactions take place chargedly, in view of the types of mechanisms involved. Different families of compounds/monomers with activation centers, both known and unknown, olefinic and non-olefinic were considered, providing their chemical behaviours under different operating conditions, based on the New Science. Unlike what is known in Present-day Science, there are Males (called Electrophiles) and Females (called Nucleophiles) compounds/monomers; indeed, more of Females than Males. While Males carry at least two different types of Activation centers cumulatively or conjugatedly placed, Females carry one, two or more same types of activation centers. How these monomers all coming from different family trees favour the routes favoured by them have been shown, even to the point where some which could not be polymerized by Present-day Science, can now be polymerized. For the first time, one has shown what the Hydrocarbon family tree looks like. In view of the absence of hetero atoms in the tree, there are no Males for those that carry Activation centers. For the first time, Azo compounds including hydrocarbons have been renamed and reclassified. How they decompose when catalyzed and non-catalyzed, have begun to be shown. They are important, because from there one began to distinguish between surface and laboratory or industrial chemistry. For the first time, one showed how membranes can be obtained from chitins. So also, one has shown how the oxidation of ortho-xylene which Present-day Science thought was also combustion to give phthalic anhydride using vanadium pentoxide takes place. From all indications, a new science has emerged.

Download or read book Half a Century of Free Radical Chemistry written by Derek H. R. Barton and published by Cambridge University Press. This book was released on 1993-04-15 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the work of Nobel Laureate Derek Barton on the chemistry of organic free radicals, and the invention of new chemical reactions for use in the synthesis of biologically and economically important compounds. It begins with a mechanistic study of industrial significance on the pyrolysis of chlorinated alkanes. It continues with a theory on the biosynthesis of phenolate derived alkaloids involving phenolate radical coupling. The book then describes the work on nitrite photolysis (Barton reaction), which involved the invention of new radical chemistry leading to a simple synthesis of the important hormone, aldosterone. It also describes another new reaction extended to carboxlic acids that provides carbon, nitrogen, oxygen and other radicals under mild conditions. A final chapter summarizes recent applications of thiocarbonyl group derived radical reactions by other authors.

Download or read book Frontiers in Organometallic Chemistry written by Marin A. Cato and published by Nova Publishers. This book was released on 2006 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: A black hole is a point of extreme mass in space-time with a radius, or event horizon, inside of which all electromagnetic radiation (including light) is trapped by gravity. A black hole is an extremely compact object, collapsed by gravity which has overcome electric and nuclear forces. It is believed that stars appreciably larger than the Sun, once they have exhausted all their nuclear fuel, collapse to form black holes: they are "black" because no light escapes their intense gravity. Material attracted to a black hole, though, gains enormous energy and can radiate part of it before being swallowed up. Some astronomers believe that enormously massive black holes exist in the centre of our galaxy and of other galaxies. This book brings together leading research from throughout the world.

Download or read book The Chemistry of Free Radicals written by Zeev B. Alfassi and published by Wiley. This book was released on 1998-11-18 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radicals play a major role as intermediates in many chemical reactions. They contribute to transformations in the atmosphere, living organisms, chemical synthesis, combustion and detonation amongst others. This comprehensive and conclusive book discusses all these aspects. N-centered Radicals deals with NOx and NCO, relatively stable radicals whose presence in the atmosphere influences the metabolism of living organisms. Also included are NHx, NCH and N3, important in radical studies, chemical synthesis, detonation and metabolism. Until now there has been no single volume bringing together all aspects of N-centered radical chemistry, from formation, to their chemistry in aqueous environments, biological systems and the atmosphere. N-centered Radicals is essential reading for researchers in organic, physical and environmental chemistry, biology and all others examining the effects of N-centered radicals.

Download or read book Advanced Organic Chemistry written by Francis A. Carey and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 829 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this edition, like that of the earlier ones, is to provide the basis for a deeper understanding of the structures of organic compounds and the mechanisms of organic reactions. The level is aimed at advanced undergraduates and beginning graduate students. Our goals are to solidify the student's understanding of basic concepts provided by an introduction to organic chemistry and to present more information and detail, including quantitative information, than can be presented in the first course in organic chemistry. The first three chapters consider the fundamental topi~s of bonding theory, stereochemistry, and conformation. Chapter 4 discusses the techniques that are used to study and characterize reaction mechanisms. Chapter 9 focuses on aromaticity and the structural basis of aromatic stabilization. The remaining chapters consider basic reaction types, including substituent effects and stereochemistry. As compared to the earlier editions, there has been a modest degree of reorganization. The emergence of free-radical reactions in synthesis has led to the inclusion of certain aspects of free-radical chemistry in Part B. The revised chapter, Chapter 12, empha sizes the distinctive mechanistic and kinetic aspects of free-radical reactions. The synthetic applications will be considered in Part B. We have also split the topics of aromaticity and the reactions of aromatic compounds into two separate chapters, Chapters 9 and 10. This may facilitate use of Chapter 9, which deals with the nature of aromaticity, at an earlier stage if an instructor so desires.
