Book Description :

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.

Book Description :

Analytical Pyrolysis presents the Proceedings of the Third International Symposium on Analytical Pyrolysis, held in Amsterdam on September 7-9, 1976. It looks at newly emergent techniques in analytical pyrolysis, including pyrolysis mass spectrometry, gas chromatography, thin-layer chromatography, and pyrolysis-gas liquid chromatography. The book also covers topics ranging from automation and microbiology to forensic science and pharmacology, reproducibility and specificity, biochemistry, laser-induced pyrolysis, pyrolytic reaction mechanisms, and polymers. Comprised of 50 chapters, this book begins with a discussion of automatic analysis of tire rubber blends using computer-linked pyrolysis gas chromatography, thermal procedures in coupling with thin-layer chromatography, the role of pyrolysis-gas liquid chromatography in biomedical studies, and the identification of microorganisms by pyrolysis gas-liquid chromatography. It then examines forensic applications of analytical pyrolysis techniques, structure and degradation behavior of synthetic polymers using pyrolysis in combination with field ion mass spectrometry, determination of polysaccharides in fulvic acids by pyrolysis gas chromatography, and application of Curie-point pyrolysis mass spectrometry in fungal taxonomy. The reader is also introduced to pyrolysis mass spectrometry of model compounds labeled with stable isotopes, the use of pyrolysis/gas chromatography to determine the quality of porous polymers of styrene cross-linked with divinyl benzene, and application of pyrohydrolysis for a rapid and accurate determination of halides in silicate rocks and minerals. This volume will benefit students, researchers, chemists, and scientists working in the field of analytical pyrolysis.

Book Description :

The high temperature pyrolysis of simple organic molecules, CH4, CCl4, CF4 and C2H2 has been studied in a shock tube. Under conditions where the final equilibrium composition is almost entirely atomic, the C2 molecule is observed to rise to a peak and thereafter decline, apparently at the same rate as the original compound is decomposing. Absolute intensity measurements on the peak C2 yield indicate that as much as 20% of the carbon atoms can form C2. By following the decay of the C2, the overall rates of decomposition of the organic materials have been obtained. The formation of C2 can be explained in terms of the reaction type CX + C yielding C2 + X. (Author).

Book Description :

The methodology of analytical pyrolysis-GC/MS has been known for several years, but is seldom used in research laboratories and process control in the chemical industry. This is due to the relative difficulty of interpreting the identified pyrolysis products as well as the variety of them. This book contains full identification of several classes of polymers/copolymers and biopolymers that can be very helpful to the user. In addition, the practical applications can encourage analytical chemists and engineers to use the techniques explored in this volume.The structure and the functions of various types of pyrolyzers and the results of the pyrolysis-gas chromatographic-mass spectrometric identification of synthetic polymers/copolymers and biopolymers at 700°C are described. Practical applications of these techniques are also included, detailing the analysis of microplastics, failure analysis in the automotive industry and solutions for technological problems.

Book Description :

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.

Book Description :

Flash pyrolysis coupled to molecular beam extraction and single photon ionization time-of-flight mass spectrometry along with quantum chemical calculations are employed to study the pyrolysis of organic molecules with relevance to combustion processes. Branching ratios for the molecular elimination and bond fission pathways was achieved for ethyl and propyl iodides providing information about the nature of the mechanism with relation to chemical structure. Similarly, the decompositions of a series of alkyl methyl ethers, whose anti-knock ability in commercial fuels is attributed to the molecular elimination pathway, was investigated to examine the competition of primary and subsequent homolyses at higher temperatures, which tend to promote "knock". The isomerization/decomposition of isoprene was looked at in detail with special attention to the formation of soot precursor, most notably the "first ring" benzene. Cyclopentadiene and methylcyclopentadiene are known to be highly sooting fuels and were pyrolyzed to study the initial steps in aromatization. The pyrolysis of cyclohexene, cyclopentene, and 1,4-cyclohexadiene were conducted to facilitate interpretation of aromatic formation and to compare experimental results with well established mechanisms. Finally, the pyrolysis of methylcyclohexane, an important component some jet fuels, was studied.
