Book Synopsis Mechanisms of Atmospheric Oxidation of the Oxygenates by : Jack Calvert
Download or read book Mechanisms of Atmospheric Oxidation of the Oxygenates written by Jack Calvert and published by Oxford University Press. This book was released on 2011-08-01 with total page 1634 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prepared by an international team of eminent atmospheric scientists, Mechanisms of Atmospheric Oxidation of the Oxygenates is an authoritative source of information on the role of oxygenates in the chemistry of the atmosphere. The oxygenates, including the many different alcohols, ethers, aldehydes, ketones, acids, esters, and nitrogen-atom containing oxygenates, are of special interest today due to their increased use as alternative fuels and fuel additives. This book describes the physical properties of oxygenates, as well as the chemical and photochemical parameters that determine their reaction pathways in the atmosphere. Quantitative descriptions of the pathways of the oxygenates from release or formation in the atmosphere to final products are provided, as is a comprehensive review and evaluation of the extensive kinetic literature on the atmospheric chemistry of the different oxygenates and their many halogen-atom substituted analogues. This book will be of interest to modelers of atmospheric chemistry, environmental scientists and engineers, and air quality planning agencies as a useful input for development of realistic modules designed to simulate the atmospheric chemistry of the oxygenates, their major oxidation products, and their influence on ozone and other trace gases within the troposhere.

Book Synopsis Oxidation of Organic Compounds by : N. M. Emanuel
Download or read book Oxidation of Organic Compounds written by N. M. Emanuel and published by Elsevier. This book was released on 2013-10-22 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The liquid-phase oxidation of organic compounds by molecular oxygen is widely encountered in nature and is of considerable im portance in various branches of the national economy. This pro cess forms the basis of many new technological processes for the production of important chemicals. At the present time, such valu able oxygen-containing compounds as synthetic aliphatiC acids and alcohols (for the replacement of edible fats), acetic, adipic, and terephthalic acids and their esters (for the production of synthetic fibers), phenol and acetone (the principal raw materials for plas tics), carbonyl compounds, ethers, and esters (as solvents and special additives) are obtained industrially by the oxidation of hy drocarbons by atmospheric oxygen in the liquid phase, that is, by the most direct and cheapest method. In the course of their production, oxygen-containing compounds (alcohols, aldehydes, ketones, acids, etc.) undergo various trans formations, which play an important role in the advanced stages of the oxidation of paraffinic, naphthenic, and alkylaromatic hydro carbons, and have a significant influence on the yield of the de sired products. For the further improvement of existing techno logical processes and the development of new methods for the pro duction of oxygen-containing compounds, detailed studies of the regular kinetic features and mechanism of their oxidation are ob viously necessary. In the past ten years, extensive material on the kinetics of the oxidation of alcohols, aldehydes, acids, ethers, and esters has ac cumulated, and the constants of the elementary stages of these complex processes have been determined.

Book Synopsis Chemical Kinetics and Mechanisms of Unsaturated Organic Aerosol Oxidation by : Theodora Nah
Download or read book Chemical Kinetics and Mechanisms of Unsaturated Organic Aerosol Oxidation written by Theodora Nah and published by . This book was released on 2014 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the heterogeneous oxidation of organic particulate matter ("aerosol") is an active area of current research in atmospheric and combustion chemistry. The chemical evolution of organic aerosol is complex and dynamic since it can undergo multiple oxidation reactions with gas phase oxidants to form a mixture of different generations of oxidation products that control the average aerosol mass and volatility. In many of these systems, hydrocarbon free radicals, formed by reaction with gas phase oxidants, play key roles as initiators, propagators and terminators of surface reactions. This dissertation presents a detailed study of the reaction kinetics and mechanisms of the heterogeneous oxidation of unsaturated organic aerosol, and aims to provide new molecular and mechanistic insights into the reaction pathways in heterogeneous organic aerosol oxidation. The heterogeneous oxidation of unsaturated fatty acid (oleic acid C18H34O2, linoleic acid C18H32O2 and linolenic acid C18H30O2) aerosol by hydroxyl (OH) radicals is first studied in Chapter 2 to explore how surface OH addition reactions initiate chain reactions that rapidly transform the chemical composition of unsaturated organic aerosol. Oleic acid, linoleic acid and linolenic acid have the same linear C18 carbon backbone structure with one, two and three C=C double bonds, respectively. By studying carboxylic acids with different numbers of C=C double bonds, the role that multiple reactive sites plays in controlling reaction rates can be observed. The kinetic parameter of interest in these studies is the effective uptake coefficient, defined as the number of particle phase unsaturated fatty acid molecules reacted per OH-particle collision. The effective uptake coefficients for the unsaturated fatty acids are larger than unity, providing clear evidence for particle-phase secondary chain chemistry. The effective uptake coefficients for the unsaturated fatty acids decrease with increasing O2 concentration, indicating that O2 promotes chain termination in the unsaturated fatty acid reactions. The kinetics and products of squalene (a C30 branched alkene with 6 C=C double bonds) oxidation are compared to that of the unsaturated fatty acids in Chapters 3 and 4 to understand how molecular structure and chemical functionality influence reaction rates and mechanisms. The squalene effective uptake coefficient, which is also larger than one, is smaller than that of linoleic acid and linolenic acid despite the larger number of C=C double bonds in squalene. In contrast to the unsaturated fatty acids, the squalene effective uptake coefficient increases with O2 concentration, indicating that O2 promotes chain propagation in the squalene reaction. Elemental and product analysis of squalene aerosol shows that O2 promotes particle volatilization in the squalene reaction, suggesting that fragmentation reactions are important when O2 is present in the OH oxidation of branched unsaturated organic aerosol. In contrast, elemental and product analysis of linoleic acid aerosol shows that O2 does not influence the rate of particle volatilization in the linoleic acid reaction, suggesting that O2 does not alter the relative importance of fragmentation reactions in the OH oxidation of linear unsaturated organic aerosol. Lastly, depending on the aerosol phase (e.g. solid and semi-solid) and the timescale for homogeneous mixing within the aerosol particle, the chemical composition may vary spatially within an aerosol particle. This necessitates the need for new techniques to characterize the interfacial chemical composition of aerosol particles. In the last portion of the dissertation, direct analysis in real time mass spectrometry (DART-MS) is used to analyze the surface chemical composition of nanometer-sized organic aerosol particles in real time at atmospheric pressure. By introducing a stream of aerosol particles in between the DART ionization source and the atmospheric pressure inlet of the mass spectrometer, the aerosol particles are exposed to a thermal flow of helium or nitrogen gas containing some fraction of metastable helium atoms or nitrogen molecules. In this configuration, the molecular constituents of organic aerosol particles are desorbed, ionized and detected with reduced molecular ion fragmentation, allowing for compositional identification. The reaction of ozone with sub-micron oleic acid particles is also measured to demonstrate the ability of DART-MS to identify products and quantify reaction rates in a heterogeneous reaction.
