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.

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.

Here in one source is a wide variety of practical, everydayinformation often required by chemists but seldom found together,if at all, in the standard handbooks, data collections, manuals,and other usual sources. Discussing physical, chemical, andmechanical properties of substances and systems, the authors answersuch questions as: * How do I test for and destroy peroxides in different solventsand what is the best way to purify such solvents? * What are the structure, physical properties, and recentreferences to the use of common-name solvents and solvent aids suchas the "Skellysolves," "Cellosolves," "Crownanes," and"Glymes"? * What is the utility of a particular molecular sieve, orpermeation gel, or epoxy cement, or liquid crystal, and where do Ibuy them and find references to their application? The book is divided into nine chapters and covers properties ofatoms and molecules, spectroscopy, photochemistry, chromatography,kinetics and thermodynamics, various experimental techniques, andmathematical and numerical information, including the definitions,values, and usage rules of the newly adopted International Systemof Units (SI Units). A section on statistical treatment of datawhich provides an actual least-squares computer program is alsoincluded. In the spectroscopy chapter, very extensive andup-to-date collections of spectral correlation data are presentedfor ir, uv-vis, optical rotation, nmr, and mass spectra, along withdata on esr and nqr spectroscopy. Also included is a variety ofhard-to-classify but frequently sought information, such as namesand addresses of microanalysis companies and chemistry publishers,descriptions and commercial sources of atomic and molecular models,and safety data for hazardous chemicals. More than 500 keyreferences are also included, most of which are recent. There areimportant hints and definitions associated with the art as well asthe state of the art for the appropriate subjects. Also foundthroughout the book are about 250 suppliers and directions forobtaining special booklets or other material. Containing a wealth of useful information, The Chemist'sCompanion will be an indispensable guide for students andprofessional chemists in nearly all the chemical disciplines. Inaddition, it will provide for the teacher and student an unusualadjunct for use in a broad cross-section of chemistry courses.
