The effective and lasting treatment of wood against insect and fungal attack grows in importance as forestry reserves decline and as cost increases feed through to the building trade and other timber users. At the same time, environmental pressures bear ever more heavily on the types of chemicals and processes employed in the preservation industry. This book records the proceedings of an international meeting arranged to address such issues. The 15 principal chapters are based upon papers by invited experts to a combined audience of preservation practitioners and non-specialists. The chapter sequence follows the logical pattern of the conference, beginning with a review of the biological threats to be contended. There follow historical and state-of-the-art accounts of aqueous, organic solvent and non-liquid treatment processes. Preservatives increasingly must meet international product and environmental standards, which along with the related test, analytical and quality control procedures, are described and referenced. Contributors from the wood preservation industry address a range of needs associated with cost, safety and performance efficacy, not neglecting a search for a better understanding of the finer chemical mechanisms involved. Remaining problems are outlined in strategies for further research and development.

Chemistry in the Utilization of Wood deals with the chemistry of wood and its technical and practical applications. It shows how the chemical nature of wood influences its properties and utilization, both as a constructional material and as the raw material for the manufacture of secondary products such as pulp and paper, cellulose derivatives, and board materials. Comprised of 12 chapters, this volume begins with an introduction to the chemical nature of wood, including a brief treatment of its anatomical structure. The discussion then turns to the chemistry of wood cell wall components such as cellulose, hemicellulose, and lignin; the principles of the methods employed in wood analysis, with emphasis on the determination of moisture content and extractives, cellulose, pentosan, and other polysaccharides; the influence of extractives on the properties and utilization of wood; and the use of timber in conjunction with chemicals. Other chapters deal with the conversion of wood into chemical products; corrosion of metals in association with wood; and the relationship between wood and water. The chemical aspects of wood attack by fungi and insects are also considered, along with destructive distillation of wood. This book is primarily intended for technical men in the wood-using industries who have an interest in wood and some knowledge of chemistry, and for students entering any field of wood technology.

Wood has played a major role throughout human history. Strong and versatile, the earliest humans used wood to make shelters, cook food, construct tools, build boats, and make weapons. Recently, scientists, politicians, and economists have renewed their interest in wood because of its unique properties, aesthetics, availability, abundance, and perhaps most important of all, its renewability. However, wood will not reach its highest use potential until we fully describe it, understand the mechanisms that control its performance properties, and, finally, are able to manipulate those properties to give us the desired performance we seek. The Handbook of Wood Chemistry and Wood Composites analyzes the chemical composition and physical properties of wood cellulose and its response to natural processes of degradation. It describes safe and effective chemical modifications to strengthen wood against biological, chemical, and mechanical degradation without using toxic, leachable, or corrosive chemicals. Expert researchers provide insightful analyses of the types of chemical modifications applied to polymer cell walls in wood. They emphasize the mechanisms of reaction involved and resulting changes in performance properties including modifications that increase water repellency, fire retardancy, and resistance to ultraviolet light, heat, moisture, mold, and other biological organisms. The text also explores modifications that increase mechanical strength, such as lumen fill, monomer polymer penetration, and plasticization. The Handbook of Wood Chemistry and Wood Composites concludes with the latest applications, such as adhesives, geotextiles, and sorbents, and future trends in the use of wood-based composites in terms of sustainable agriculture, biodegradability and recycling, and economics. Incorporating decades of teaching experience, the editor of this handbook is well-attuned to educational demands as well as industry standards and research trends.

The Chemical Technology of Wood is an eight-chapter introductory text on the developments in understanding the chemistry of wood and its chemical-technological utilization. The opening chapters of this book cover the productive aspects of forests, followed by a description of the anatomy and physical properties of wood. The subsequent chapter presents a summative wood analysis concerning its cellulose, hemicelluloses, lignin, and other extraneous components. This topic is followed by a presentation of several destructive processing of wood, including acid hydrolysis, pyrolysis, oxidation, and hydrogenolysis. The remaining chapters describe the pulp production through sulfite cooking and using alkaline reagents. This book will prove useful to chemists, engineers, biologists, foresters, and economists.
