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 of Synthetic Organic Polymers is a follow-up to Analytical Pyrolysis of Natural Organic Polymers, which is volume 20 of the series. The main focus of the book is on practical applications of analytical pyrolysis in synthetic organic polymer identification and characterization. The first part of the book has five chapters including an introduction, a discussion on physico-chemistry of thermal degradation of synthetic polymers and on instrumentation used in analytical pyrolysis, a chapter discussing what type of information can be obtained from analytical pyrolysis, and a chapter dedicated to the analysis and characterization of synthetic polymers.The second part systematically covers the analytical pyrolysis of various classes of synthetic polymers. Some theoretical background for the understanding of polymer structure using analytical pyrolysis is also discussed.* Includes broad coverage of organic synthetic macromolecules* Focuses on physico-chemistry of thermal degradation, and the analytical pyrolysis of various classes of synthetic polymers* Is well written and suitable for both researchers and chemists working in analytical chemistry or in synthetic polymers

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.

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).
