Cellulose Derivatives

This book summarizes recent progress in cellulose chemistry. The last 10 years have witnessed important developments, because sustainability is a major concern. Biodegradable cellulose derivatives, in particular esters and ethers, are employed on a large scale. The recent developments in cellulose chemistry include unconventional methods for the synthesis of derivatives, introduction of novel solvents, e.g. ionic liquids, novel approaches to regioselective derivatization of cellulose, preparation of nano-particles and nano-composites for specific applications. These new developments are discussed comprehensively. This book is aimed at researchers and professionals working on cellulose and its derivatives. It fills an important gap in teaching, because most organic chemistry textbooks concentrate on the relatively simple chemistry of mono- and disaccharides. The chemistry and, more importantly, the applications of cellulose are only concisely mentioned.

Many highly acclaimed and authoritative books on polymer science tend to focus on synthetic polymers. Cellulose and Cellulose Derivatives is the first authoritative book on the subject. It examines recent developments, with particular reference to cellulose (in aqueous alkali) and cellulose acetate. Packed with examples, the author takes an in-depth look at the topic, using the most reliable experimental data available. A comprehensive approach to the fundamental principles of cellulose and its derivatives in solution makes Cellulose and Cellulose Derivatives ideal reading for novices as well as experienced cellulose scientists. * Outlines the theoretical fundamentals of cellulose and cellulose derivatives * Presents comprehensive and reliable experimental results in figures and tables * Highly illustrated and easy to read

Cellulose and its derivatives can be found in many forms in nature and is a valuable material for all manner of applications in industry. This book is authored by an expert with many years of experience as an application engineer at renowned cellulose processing companies in the food industry. All the conventional and latest knowledge available on cellulose and its derivatives is presented. The necessary details are elucidated from a theoretical and practical viewpoint, while retaining the focus on food applications. This book is an essential source of information and includes recommendations and instructions of a general nature to assist readers in the exploration of possible applications of cellulose and its derivatives, as well as providing food for thought for the generation of new ideas for product development. Topics include gelling and rheological properties, synergistic effects with other hydrocolloids, as well as nutritional and legal aspects. The resulting compilation covers all the information and advice needed for the successful development, implementation, and handling of cellulose-containing products.

Cellulose as an abundant renewable material has stimulated basic and applied research that has resulted in significant progress in polymer science. This book discusses reliable crystal structures of all cellulose polymorphs and cellulose derivatives. Models are represented in graphs, together with a collection of geometrical data and the atomic coordinates. This book is a concise guide for members of the materials and life sciences communities interested in cellulose and related materials.

The proceedings of the Cellucon Trust conference held in Lund, Sweden, in 1993. The latest scientific advances are covered, environmental concerns and the consequent economic costs are dealt with. The papers have surprisingly wide applications across a number of industries, including food processing, pharmaceuticals, chemical processing, civil engineering and composite materials production.

This monograph is concerned with systematization of the infrared spectra of an important natural polymer, cellulose, and its derivatives. The infrared spectra of the main classes of cellulose derivatives are de scribed and interpreted and those of such model compounds as mono-, di-, and trisaccharides are considered. Considerable attention is given to prob lems of technique in obtaining infrared spectra of fibrous cellulose materials, and to the analytical possibilities of infrared spectroscopy in studies of the properties of cellulose and its derivatives. The book will be of use to scientific and plant workers interested in the study and treatment of cellulose, compounds related to cellulose (carbo hydrates and polycarbohydrates), and other polymers. v INTRODUCTION Spectroscopy has nowadays acquired great scientific and practical im portance. Its possibilities are based on the specificity of the emission and ab sorption spectra of all types of material, from elements to complex natural products. Most widely used are the methods of emission spectral analysis (analysis of the emission spectrum from an incandescent body). The rapidity and availability of these methods, together with their high sensitivity and selectivity, has made them indispensable in the practice of plant and scien tific laboratories for establishing the presence of specific elements in a sub stance under investigation.

Cellulose is the principal constituent of all plant life; it is the most abundant, important and fascinating biopolymer on earth. Cellulose, as an almost inexhaustible, environmentally benign and renewable material, has stimulated basic and applied research as well as inspired significant progress in Polymer Science. In recent years, cellulose has gained renewed importance as a raw material. Although ground breaking research is carried out on cellulose, it still possesses high potential for future applications; it can be easily modified to more natural and sustainable alternatives compared to synthetic products by certain techniques. The present book reviews some vital issues and topics on the latest science and technological advances in cellulose and its derivatives. This catalog acts as an essential source of information to readers in the exploration for possible applications of cellulose and its derivatives. The authors hope this collection will spark a generation of new ideas for product development. The present book contains 25 invited contributions written by leading experts in the field of cellulose and cellulose derivatives. It is divided into three parts: Part I, Cellulose Synthesis and Modification; Part II, Cellulose Derivatives; and Part III, Applications of Cellulose Derivatives. Highlights of this book include the mechanism of cellulose formation in biosynthetical processes; surface modification and functionalisation of cellulose fibers; advances in the homogenous and heterogeneous phase modification of cellulose to create unusual and functional derivatives; analysis and characterisation of modified derivatives; derivatives for antimicrobial, medical and pharmaceutical applications, and wastewater treatment; dendronised and hyperbranched cellulose derivatives; and rheology of nanocellulosic systems.
