Verified Synthesis of Zeolitic Materials
Author: H. RobsonPublisher: Gulf Professional Publishing
ISBN: 9780444507037
Category : Architecture
Languages : en
Pages : 288
Book Description
Zeolite synthesis is an active field of research. As long as this continues, new phases will be discovered and new techniques for preparing existing phases will appear. This edition of Verified Synthesis of Zeolitic Materials contains all the recipes from the first edition plus 24 new recipes. Five new introductory articles have been included plus those from the first edition, some of which have been substantially revised. The XRD patterns have been recorded using different instrument settings from those in the first edition and are intended to conform to typical X-ray diffraction practice. In most cases, only the XRD pattern for the productas synthesised is printed here. The exceptions are those phases which show marked changes in the XRD pattern upon calcination.

Superbases for Organic Synthesis
Author: Tsutomu IshikawaPublisher: John Wiley & Sons
ISBN: 9780470740866
Category : Science
Languages : en
Pages : 336
Book Description
Guanidines, amidines and phosphazenes have been attracting attention in organic synthesis due to their potential functionality resulting from their extremely strong basicity. They are also promising catalysts because of their potential for easy molecular modification, possible recyclability, and reduced or zero toxicity. Importantly, these molecules can be derived as natural products – valuable as scientists move towards “sustainable chemistry”, where reagents and catalysts are derived from biomaterial sources. Superbases for Organic Synthesis is an essential guide to these important molecules for preparative organic synthesis. Topics covered include the following aspects: an introduction to organosuperbases physicochemical properties of organic superbases amidines and guanidines in organic synthesis phosphazene: preparation, reaction and catalytic role polymer-supported organosuperbases application of organosuperbases to total synthesis related organocatalysts: proton sponges and urea derivatives amidines and guanidines in natural products and medicines Superbases for Organic Synthesis is a comprehensive, authoritative and up-to-date guide to these important reagents for organic chemists, drug discovery researchers and those interested in the chemistry of natural products.

Author: Chemistry and Applications of Polyphosphazenes
Author: Harry R. AllcockPublisher: Wiley-Interscience
ISBN: 9780471443711
Category : Technology & Engineering
Languages : en
Pages : 0
Book Description
Polyphosphazenes are polymers containing nitrogen as part of their backbone; they are commonly used in O-rings, pipelines, and seals in oil, fuel delivery, and storage systems. New polyphosphazene derivatives have been proven biocompatible, biodegradable, and bioactive, and some of them are being investigated for possible medical applications. Harry Allcock’s Chemistry and Applications of Polyphosphazenes provides the only published compilation of material on polyphosphazenes, detailing synthetic methodologies and physical properties for each substance. Allcock explains the critical relationships between structure and properties, aiding the practicing researcher in the design of polyphosphazenes with specific applications. Professionals and students in polymer science, engineering, and industries such as rubbers and plastics will find Chemistry and Applications of Polyphosphazenes to be an invaluable text.

Polymer Characterisation
Author: B.J. HuntPublisher: Springer Science & Business Media
ISBN: 9401121605
Category : Science
Languages : en
Pages : 376
Book Description
Polymers continue to play an ever increasing role in the modern world. In fact it is quite inconceivable to most people that we could ever have existed of the increased volume and variety of materials without them. As a result currently available, and the diversity of their application, characterisation has become an essential requirement of industrial and academic laboratories in volved with polymeric materials. On the one hand requirements may come from polymer specialists involved in the design and synthesis of new materials who require a detailed understanding of the relationship between the precise molecular architecture and the properties of the polymer in order to improve its capabilities and range of applications. On the other hand, many analysts who are not polymer specialists are faced with the problems of analysing and testing a wide range of polymeric materials for quality control or material specification purposes. We hope this book will be a useful reference for all scientists and techno or industrial laboratories, logists involved with polymers, whether in academic and irrespective of their scientific discipline. We have attempted to include in one volume all of the most important techniques. Obviously it is not possible to do this in any great depth but we have encouraged the use of specific examples to illustrate the range of possibilities. In addition numerous references are given to more detailed texts on specific subjects, to direct the reader where appropriate. The book is divided into II chapters.

Book Description
Polymers are used in everything from nylon stockings to commercial aircraft to artificial heart valves, and they have a key role in addressing international competitiveness and other national issues. Polymer Science and Engineering explores the universe of polymers, describing their properties and wide-ranging potential, and presents the state of the science, with a hard look at downward trends in research support. Leading experts offer findings, recommendations, and research directions. Lively vignettes provide snapshots of polymers in everyday applications. The volume includes an overview of the use of polymers in such fields as medicine and biotechnology, information and communication, housing and construction, energy and transportation, national defense, and environmental protection. The committee looks at the various classes of polymersâ€"plastics, fibers, composites, and other materials, as well as polymers used as membranes and coatingsâ€"and how their composition and specific methods of processing result in unparalleled usefulness. The reader can also learn the science behind the technology, including efforts to model polymer synthesis after nature's methods, and breakthroughs in characterizing polymer properties needed for twenty-first-century applications. This informative volume will be important to chemists, engineers, materials scientists, researchers, industrialists, and policymakers interested in the role of polymers, as well as to science and engineering educators and students.
