Available in PDF, EPUB and Kindle. Book excerpt: Pyrolytic Methods in Organic Chemistry: Application of Flow and Flash Vacuum Pyrolytic Techniques is concerned with the use of flow pyrolysis and flash vacuum pyrolysis in preparative organic chemistry. Topics covered include pyrolytic generation and reactions of free radicals, arynes, and cyclobutadienes; elimination reactions; rearrangements of carbenes and nitrenes in the gas phase; and fragmentation of cyclic and acyclic structures. Examples of the types of reaction for which flow and flash pyrolytic methods are well suited are provided. This book is comprised of nine chapters and begins by discussing the place of flow and flash vacuum pyrolytic methods in organic chemistry. The next chapter gives an account of apparatus and experimental methods, while the remaining chapters focus on pyrolytic reactions that are grouped together according to the nature of the overall process, the formal structure of the starting material, and mechanistic type. Reactions that are formally related because they involve elimination of a small fragment molecule X-X or X-Y from a larger molecular framework are examined, along with cleavage of carbocyclic systems. The final chapter presents examples of high-temperature rearrangements, focusing on electrocyclic reactions and cycloadditions involving mainly four or six electrons; reactions that proceed through diradical intermediates; and isomerizations of heterocyclic rings. This monograph is intended mainly for practicing academic and industrial organic chemists and for advanced and graduate students.

Available in PDF, EPUB and Kindle. Book excerpt: Analytical pyrolysis is one of the many tools utilized for the study of natural organic polymers. This books describes in three parts the methodology of analytical pyrolysis, the results of pyrolysis for a variety of biopolymers, and several practical applications of analytical pyrolysis on natural organic polymers and their composite materials. Analytical pyrolysis methodology covers two distinct subjects, the instrumentation used for pyrolysis and the analytical methods that are applied for the analysis of the pyrolysis products. A variety of pyrolytic techniques and of analytical instruments commonly coupled with pyrolysis devices are given. The description of the results of pyrolysis for biopolymers and some chemically modified natural organic polymers is the core of the book. The main pyrolysis products of numerous compounds as well as the proposed mechanisms for their pyrolysis are described. In this part an attempt is made to present as much as possible the chemistry of the pyrolytic process of natural organic polymers. The applications of analytical pyrolysis include topics such as polymer detection used for example in forensic science, structure elucidation of specific polymers, and identification of small molecules present in polymers (anti-oxidants, plasticizers, etc.). Also, the degradation during heating is a subject of major interest in many practical applications regarding the physical properties of polymers. The applications to composite polymeric materials are in the fields of classification of microorganisms, study of a variety of biological samples, study of fossil materials, etc. Analytical pyrolysis can also be used for obtaining information on the burning area generate pyrolysates that have complex compositions. Their analysis is important in connection with health issues, environmental problems, and taste of food and cigarettes. Features of this book: • Presents analytical pyrolysis as a uniform subject and not as a conglomerate of scientific papers. • Puts together in an organized manner a large volume of available information in this specific field. • Provides original results which address subjects with relatively scarce information in literature. • Gives original views on subjects such as the parallel between the pyrolytic process and the ion fragmentation in mass spectrometry. • Includes the role of pyrolysis in the burning process. The three parts of the book are covered in 18 chapters, each divided into sections. Some sections are further divided by particular subjects. References are given for each chapter, and an effort has been made to include as much as possible from the available representative information. A few unpublished personal results are also included.

Available in PDF, EPUB and Kindle. Book excerpt: In this data book, both conventional Py-GC/MS where thermal energy alone is used to cause fragmentation of given polymeric materials and reactive Py-GC/MS in the presence of organic alkaline for condensation polymers are compiled. Before going into detailed presentation of the data, however, acquiring a firm grip on the proper understanding about the situation of Py-GC/MS would promote better utilization of the following pyrolysis data for various polymers samples. This book incorporates recent technological advances in analytical pyrolysis methods especially useful for the characterization of 163 typical synthetic polymers. The book briefly reviews the instrumentation available in advanced analytical pyrolysis, and offers guidance to perform effectually this technique combining with gas chromatography and mass spectrometry. Main contents are comprehensive sample pyrograms, thermograms, identification tables, and representative mass spectra (MS) of pyrolyzates for synthetic polymers. This edition also highlights thermally-assisted hydrolysis and methylation technique effectively applied to 33 basic condensation polymers. Coverage of Py-GC/MS data of conventional pyrograms and thermograms of basic 163 kinds of synthetic polymers together with MS and retention index data for pyrolyzates, enabling a quick identification Additional coverage of the pyrograms and their related data for 33 basic condensation polymers obtained by the thermally-assisted hydrolysis and methylation technique All compiled data measured under the same experimental conditions for pyrolysis, gas chromatography and mass spectrometry to facilitate peak identification Surveyable instant information on two facing pages dedicated to the whole data of a given polymer sample

Book excerpt: Analytical Pyrolysis: Techniques and Applications provides an overview of analytical pyrolysis applied to geochemistry, biology, polymers, and biomass. This book presents a survey of basic phenomena, data analysis, and instrumentation. Organized into 15 chapters, this book begins with an overview of mass spectrometry in developing ion sources that are applicable to materials that either have low volatility, high molecular weight, are thermally unstable or some combination of the three. This text then examines the role of thermal processes in many of the desorption methods. Other chapters consider desorption techniques, which are closely allied to analytical pyrolysis. This book discusses as well the Flash Vacuum Pyrolysis/Field Ionization Mass Spectrometry (FVP/FIMS) technique, which is based on a direct link between the pyrolysis unit and a double focusing mass spectrometer. The final chapter deals with inert atmosphere poly (vinyl chloride) (PVC) thermal decomposition. This book is a valuable resource for chemists and researchers.

Available in PDF, EPUB and Kindle. Book excerpt: Pyrolysis is an irreversible thermochemical treatment process of materials at elevated temperatures in an inert atmosphere. It is basically a carbonisation process where an organic material is decomposed to produce a solid residue with high (or higher) carbon content and some volatile products. The decomposition reactions are accompanied in general with polymerisation and isomerisation reactions. The end products of pyrolysis can be controlled by optimizing pyrolysis parameters such as temperature and residence time. Pyrolysis is used heavily in the chemical industry to produce many forms of carbon and other chemicals from petroleum, coal, wood, oil shale, biomass or organic waste materials, and it is the basis of several methods for producing fuel from biomass. Pyrolysis also is the process of conversion of buried organic matter into fossil fuels.
