This book was released on 1971 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is desirable to know the degree of the thermal decomposition of motor oils, at elevated temperatures in both neutral and oxidizing media. To test for this property, the authors used thermogravimetric analysis. When an oil sample is heated in a neutral medium some of its components evaporate. When the sample is heated in air, evaporation occurs at first, but soon thereafter oxidation and decomposition take place as well. The correlation between the loss of mass (evaporation) and the temperature is indicative of the oil's fractional composition in the first case and of its resistance to thermal decomposition in the second case.

Available in PDF, EPUB and Kindle. Book excerpt: Introduction to Infrared and Raman Spectroscopy focuses on the theoretical and experimental aspects of infrared and Raman spectroscopy, with emphasis on detailed group frequency correlations and their vibrational origin. Topics covered include vibrational and rotational spectra, molecular symmetry, methyl and methylene groups, triple bonds and cumulated double bonds, and olefin groups. Aromatic and heteroaromatic rings are also considered, along with carbonyl compounds and molecular vibrations. This book is comprised of 14 chapters and begins with a discussion on the use of Raman and infrared spectroscopy to study the vibrational and rotational frequencies of molecules, paying particular attention to photon energy and degrees of freedom of molecular motion. The quantum mechanical harmonic oscillator and the anharmonic oscillator are described. The next chapter focuses on the experimental techniques and instrumentation needed to measure infrared absorption spectra and Raman spectra. Symmetry is then discussed from the standpoint of the spectroscopist. The following chapters explore the vibrational origin of group frequencies, with an emphasis on mechanical effects; spectra-structure correlations; and the spectra of compounds such as ethers, alcohols, and phenols. The final chapter demonstrates how the frequencies and forms of a nonlinear molecule's normal modes of vibration may be calculated mathematically. This monograph will be a useful resource for spectroscopists and physical scientists.

Download or read book Thermal Desorption Studies of Volatiles Released During Heating of Food Oils written by Ilona Repko Reader and published by . This book was released on 2013 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lipid degradation occurs extensively during deep fat frying, and controlling it is a great challenge, at least in part because the reaction mechanisms responsible remain controversial. With current trends towards increasing unsaturated fats in frying oils, a more complete understanding of these pathways becomes critical. To gain more detailed information about reactions involved in thermal decomposition kinetics and products of frying oils, corn oil/ high oleic sunflower oil blends (fresh, stripped, and steady-state) were heated at 180℗ʻC for three hours in an OxipresTM oxygen bomb under 2 bars air pressure. Upon release of pressure, the headspace was vented through a Tenax-Carboxen thermal desorption trap to trap volatiles which were then identified and quantitated by gas chromatography-mass spectrometry. Volatile levels and distributions were integrated with oxygen consumption and non-volatile product data from another study to assess relative contributions of thermal scission and autoxidation reaction mechanisms in overall degradation. Effects of catalytic factors on oil degradation were evaluated by adding metals, phospholipids, fatty acids, and water to the oil blends during heating. Fresh, stripped, and steady-state oils all generated comparable volatile products, but with differing concentrations and distributions. The main peaks coeluting isopentane/ pentane octane/ hexanal> pentanal/heptanes. Peak analyses revealed homologous series of alkanes, aldehydes, alkenes, ketones, cycloalkanes, and furans were also present. Levels of products generally decreased with chain length. No 2,4-decadienal was detected. This product pattern and the kinetics of evolution of different products provides strong support for thermal scission as the dominant degradation mechanism that occurs first to generate scission radicals that yield alkanes directly or oxidize to hydroperoxides, aldehydes, and carboxylic acids. Secondary reactions then initiate autoxidation chains. Factors known to have strong effects on lipid oxidation at room temperature appear to influence product distribution rather than degradation kinetics in heated oils. Integration of volatiles and non-volatiles data with oxygen consumption suggests there are pathways active in thermal degradation that are not being accounted for in current analyses, and these need to be elucidated to fully understand how various factors influence oil degradation as well as to learn how to improve frying oil stabilization.

Available in PDF, EPUB and Kindle. Book excerpt: As global consumption of fossil fuels such as oil increases, previously abundant sources have become depleted or plagued with obstructions. Asphaltene deposition is one of such obstructions which can significantly decrease the rate of oil production. This book offers concise yet thorough coverage of the complex problem of asphaltene precipitation and deposition in oil production. It covers fundamentals of chemistry, stabilization theories and mechanistic approaches of asphaltene behavior at high temperature and pressure. Asphaltene Deposition: Fundamentals, Prediction, Prevention, and Remediation explains techniques for experimental determination of asphaltene precipitation and deposition and different modeling tools available to forecast the occurrence and magnitude of asphaltene deposition in a given oil field. It discusses strategies for mitigation of asphaltene deposition using chemical inhibition and corresponding challenges, best practices for asphaltene remediation, current research, and case studies.

This book was released on 2013-06-29 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: The material presented in this book deals with basic mechanisms of free radical reactions in autoxidation processes and anitoxidant suppression of autoxidation of foods, biochemical models and biologi cal systems. Autoxidation in foods and corresponding biological effects are usually approached separately although recent mechanistic developments in the biochemistry and free radical chemistry of per oxides and their precursors tend to bring these two fields closer. Apparent ability of antioxidants in diets to reduce the inci dence of cancer has resulted in scrutiny of autoxidized products and their precursors as possibly toxic, mutagenic and carcinogenic agents. Mechanisms of any of these effects have been barely ad dressed. Yet we know now that free radicals, as esoteric as they were only a few decades ago, are being discovered in foods, biochem ical and biological systems and do play a role in the above-mentioned causalities. The purpose of the Workshop and the resulting book was to give a unifying approach towards study of beneficial and deleterious effects of autoxidation, based on rigorous scientific considerations. It is our hope that the material presented in this book will not only provide a review of the "state of the art" of autoxidation and anti oxidants, but also reflect the interaction which occurred during the Workshop between workers using model sytems, and food and biological systems.
