The Determination of Organic Peroxides


Book Description

Monographs in Organic Functional Group Analysis, Volume 4: The Determination of Organic Peroxides focuses on the analytical chemistry of organic peroxides. The monograph first offers information on the compositions, properties, and reactions of lipid peroxides, polymers, and petrochemicals. The text then reviews the iodometric methods, including choice of solvents, reaction conditions, and titration with thiosulfate. The ferrous ion methods are also discussed. Considerations include choice of reagents and solvents and titration with titanous, dichromate, and mercurous ions. The book also focuses on titrimetric methods, including arsenious, stannous, and titanous methods, titration with anions, and sulfides and mercaptans. Numerical representations are provided. The text puts emphasis on colorimetric and polarographic methods. Polarographic techniques for peroxides; nature and concentration of peroxides; leuco base of methylene blue; and ferrous ions are described. The book also discusses paper, thin-layer, and gas chromatography. The monograph is an important guide for readers interested in the analytical chemistry of organic peroxides.




Determination of Additives in Polymers and Rubbers


Book Description

This book is designed as a practical text for use in the laboratories of the plastic producer and user industries and by others such as universities and institutions who are concerned with problems associated with additives and adventitious impurities in polymers. For example, powerful new analytical tools have been made available to the chemist by a combination of various chromatographic techniques with methods of identifying separated additives and their degradation products by techniques based on infrared and mass spectrometry. In particular supercritical fluid chromatography combined with m.







Tables of Spectral Data for Structure Determination of Organic Compounds


Book Description

Although numerical data are, in principle, universal, the compilations presented in this book are extensively annotated and interleaved with text. This translation of the second German edition has been prepared to facilitate the use of this work, with all its valuable detail, by the large community of English-speaking scientists. Translation has also provided an opportunity to correct and revise the text, and to update the nomenclature. Fortunately, spectroscopic data and their relationship with structure do not change much with time so one can predict that this book will, for a long period of time, continue to be very useful to organic chemists involved in the identification of organic compounds or the elucidation of their structure. Klaus Biemann Cambridge, MA, April 1983 Preface to the First German Edition Making use of the information provided by various spectroscopic tech niques has become a matter of routine for the analytically oriented organic chemist. Those who have graduated recently received extensive training in these techniques as part of the curriculum while their older colleagues learned to use these methods by necessity. One can, therefore, assume that chemists are well versed in the proper choice of the methods suitable for the solution of a particular problem and to translate the experimental data into structural information.

Chemical Analysis of Additives in Plastics


Book Description

International Series in Analytical Chemistry, Volume 46: Chemical Analysis of Additives in Plastics, Second Edition brings together numerous investigations on the characterization, identification, and determination of various types of additives in plastics. This book is divided into five chapters. Chapters 1 and 2 describe first the methods for examining additives present in polymers based on either direct spectroscopy of a cast polymer film or on solvent extraction of total additives from the polymer followed by quantitative chemical or physical analysis for various components in the extract. Chapter 3 discusses the application of thin-layer and column chromatography to the separation and determination of known additives. Chapters 4 and 5 examine the application of combined chromatographic and spectroscopic techniques for the separation and determination of unknown plastics additives. This book will prove useful to plastics manufacturers, researchers, institutions, and universities.




Practical Polymer Analysis


Book Description

The aim of this book is to familiarize the reader with the practical aspects of polymer analysis. A wealth of practical detail, including some detailed methods is included. The book covers not only the analysis of the main types of polymers and copolymers now in use commercially, but also the analysis of minor non-polymeric components of the polymer formulation, whether they be deliberately added, such as processing additives, or whether they occur adventitiously, such as moisture and residual monomers and solvent. A broad scheme for the examination of polymers is discussed in Chapter 2. Practically all of the major newer analytical techniques and many of the older classical techniques, have been used to examine polymers and their additive systems. As so many different polymers are now used commercially it is also advisable when attempting to identify a polymer to classify it by first separating it into pure polymeric and gross non polymeric fractions (Chapter Z) and then carrying out at least a qualitative elemental analysis and possible a quantitative analysis (Chapters 3 and 4) and then in some cases, depending on the elements found, to carry out functional group analysis (Chapters 6 and 9).




Chromatographic Analysis of the Environment, Third Edition


Book Description

Chromatographic Analysis of the Environment, Third Edition is a detailed handbook on different chromatographic analysis techniques and chromatographic data for compounds found in air, water, soil, and sludge. Taking on a new perspective from previous editions, this third edition discusses the parameters of each environmental compartment in a consistent format that highlights preparation techniques, chromatographic separation methods, and detection methods. Most of the data are compiled in tables and figures to elucidate the text as needed. Separate chapters approach specific aspects of sampling methods especially designed for environmental purposes, quantification of environmental analytes in difficult matrices, and data handling. The second part of the book focuses on the analysis of hazardous chemicals in the environment, including volatile organic carbons (VOCs), polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and endocrine-disrupting chemicals (EDCs). In addition, the authors feature information on compounds such as phosphates, organic acids, halogenated VOCs, amines, and n-ntirosamines, isocyanates, phthalate esters, and humic substances. Presenting important theoretical and practical aspects from sample collection to laboratory analysis, Chromatographic Analysis of the Environment, Third Edition is a unique resource of chromatographic techniques, data, and references that are useful to all scientists involved in the analysis of environmental compounds.
