Oxidation of Organic Compounds: Medium Effects in Radical Reactions explores the role of solvents and of the composition of phase states in radical-chain processes involved in the oxidation of organic compounds. Organized into 10 chapters, this book begins with a discussion of the basic concepts relating to the mechanism involved in the oxidation of hydrocarbons and other organic compounds in liquid-phase reactions. Subsequent chapters detail some methods for studying the mechanism of oxidation reactions; role of solvation in chemical reaction kinetics; role of the medium in chain-initiation reactions; role of non-specific and specific solvation in chain-propagation and chain-termination reactions; and the role of solvation in chain-termination reactions in inhibitors. The influence of the solvent and the phase state of substances undergoing oxidation on the rates and mechanisms of individual elementary processes are also addressed. The last chapter examines the problem of the influence of the solid state of the polymer on the reactivity of radicals. This monograph will be valuable to scientific research workers, engineers, and engineering technologists specializing in the field of radical reactions and in particular in the oxidation of organic compounds.

Sets the stage for environmentally friendly industrial organic syntheses From basic principles to new and emerging industrial applications, this book offers comprehensive coverage of heterogeneous liquid-phase selective oxidation catalysis. It fully examines the synthesis, characterization, and application of catalytic materials for environmentally friendly organic syntheses. Readers will find coverage of all the important classes of catalysts, with an emphasis on their stability and reusability. Liquid Phase Oxidation via Heterogeneous Catalysis features contributions from an international team of leading chemists representing both industry and academia. The book begins with a chapter on environmentally benign oxidants and then covers: Selective oxidations catalyzed by TS-1 and other metal-substituted zeolites Selective catalytic oxidation over ordered nanoporous metallo-aluminophosphates Selective oxidations catalyzed by mesoporous metal-silicates Liquid phase oxidation of organic compounds by supported metal-based catalysts Selective liquid phase oxidations in the presence of supported polyoxometalates Selective oxidations catalyzed by supported metal complexes Liquid phase oxidation of organic compounds by metal-organic frameworks Heterogeneous photocatalysis for selective oxidations with molecular oxygen All the chapters dedicated to specific types of catalysts follow a similar organization and structure, making it easy to compare the advantages and disadvantages of different catalysts. The final chapter examines the latest industrial applications, such as the production of catechol and hydroquinone, cyclohexanone oxime, and propylene oxide. With its unique focus on liquid phase heterogeneous oxidation catalysis, this book enables researchers in organic synthesis and oxidation catalysis to explore and develop promising new catalytic materials and synthetic routes for a broad range of industrial applications.

The Oxidation of Cyclohexane focuses on the processes, methodologies, reactions, and approaches involved in the oxidation of cyclohexane. The publication first offers information on the theory of slow chain oxidations and the products of liquid-phase cyclohexane oxidation. Discussions focus on the applicability of the stationary state method to liquid-phase oxidation reactions; mechanism of liquid hydrocarbon chain oxidation; kinetic equations for product accumulation in degenerate branching chain reactions; and changes of the volume of the liquid phase due to oxidation product formation. The text then ponders on experimental apparatus for the study of the liquid-phase oxidation of cyclohexane, including prevention of cyclohexane losses in the waste gases, explosion danger and problems of safety, and characteristics of gas sampling in cyclohexane oxidation apparatus. The manuscript takes a look at the kinetics of uncatalyzed cyclohexane oxidation and kinetics of cyclohexane oxidation in continuous flow systems. Topics include effect of temperature on the relative yield of cyclohexane oxidation products; kinetics of cyclohexane oxidation in a glass reactor; rate of oxygen absorption and accumulation of reaction products; ideal displacement reactor; and determination of diffusion factor. The publication is a dependable reference for readers interested in the oxidation of cyclohexane.

Since the early 1970s, experts have recognized that petroleum pollutants were being discharged in marine waters worldwide, from oil spills, vessel operations, and land-based sources. Public attention to oil spills has forced improvements. Still, a considerable amount of oil is discharged yearly into sensitive coastal environments. Oil in the Sea provides the best available estimate of oil pollutant discharge into marine waters, including an evaluation of the methods for assessing petroleum load and a discussion about the concerns these loads represent. Featuring close-up looks at the Exxon Valdez spill and other notable events, the book identifies important research questions and makes recommendations for better analysis ofâ€"and more effective measures againstâ€"pollutant discharge. The book discusses: Inputâ€"where the discharges come from, including the role of two-stroke engines used on recreational craft. Behavior or fateâ€"how oil is affected by processes such as evaporation as it moves through the marine environment. Effectsâ€"what we know about the effects of petroleum hydrocarbons on marine organisms and ecosystems. Providing a needed update on a problem of international importance, this book will be of interest to energy policy makers, industry officials and managers, engineers and researchers, and advocates for the marine environment.

The first book to place recent academic developments within the context of real life industrial applications, this is a timely overview of the field of aerobic oxidation reactions in the liquid phase that also illuminates the key challenges that lie ahead. As such, it covers both homogeneous as well as heterogeneous chemocatalysis and biocatalysis, along with examples taken from various industries: bulk chemicals and monomers, specialty chemicals, flavors and fragrances, vitamins, and pharmaceuticals. One chapter is devoted to reactor concepts and engineering aspects of these methods, while another deals with the relevance of aerobic oxidation catalysis for the conversion of renewable feedstock. With chapters written by a team of academic and industrial researchers, this is a valuable reference for synthetic and catalytic chemists at universities as well as those working in the pharmaceutical and fine chemical industries seeking a better understanding of these reactions and how to design large scale processes based on this technology.

Polymers play a vital role in manufacturing processes of many kinds, and the development of new polymeric materials is of increasing importance in the field of materials science. Because of this, there is a need to understand why the properties of polymers change, what can be done to avoid degradation and failure, and how performance can be maintained over a much longer lifespan. The authors deal firstly with the process of degradation through oxidation, and then explain how the addition of various antioxidants can inhibit or retard this process. They present a unique discussion of the physico-chemical aspects, particularly the chemical kinetics of antioxidant action and of branched chain reaction kinetics, and the theory of critical phenomena inhibited oxidation. The last part of the book offers practical advice on methods of oxidation investigation, on selection of appropriate antixodants, and on the basic principles of performance prognosis. The book also includes a unique coverage of the regularities of additive solubility.
