Book Synopsis Wood Extractives and Their Significance to the Pulp and Paper Industries by : W. E. Hillis
Download or read book Wood Extractives and Their Significance to the Pulp and Paper Industries written by W. E. Hillis and published by Academic Press. This book was released on 2014-05-12 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood Extractives and their Significance to the Pulp and Paper Industries focuses on the promotion of the study of the biochemistry of wood extractives and to elaborate on the effects these materials may pose to the manufacture of pulp and paper. The publication first elaborates on wood, distribution and formation of polyphenols within the tree, and the simple polyphenolic constituents of plants. Discussions focus on the factors affecting the amounts of polyphenols present in living tissues, glycosidic combination, flavonols, anthocyanins, and leucoanthocyanins, formation of carbohydrates in the tree, types of polyphenols in different tissues of uninjured trees, and variation in structure and properties of wood. The text then examines lignans and condensed and hydrolyzable tannins. The manuscript takes a look at the alicyclic acid precursors of polyphenols, biosynthesis of polyphenols, and tropolones. Topics include tropolones occurring in wood, polymeric polyphenols, synthesis of pre-aromatic compounds, shikimic acid, and quinic acid. The book then ponders on the influence of extractives on the pulping of wood and the influence of extractives on the color of ground wood and newsprint. The publication is a valuable reference for researchers interested in the processes and methodologies involved in the manufacture of pulp and paper.

Book Synopsis Heartwood and Tree Exudates by : William E. Hillis
Download or read book Heartwood and Tree Exudates written by William E. Hillis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why prepare a treatise on Heartwood and Tree Exudates? Why consider both topics together? What approach should be taken in their treatment? The exudates were one of the earliest items of trade between family, tribal, and racial groupings in prehistoric times. They became used extensively as items for the manufacture of implements and as commercial goods for illumination, for cosmetic, religious and magical purposes. Later heartwood from various trees entered intra and international trade for prestigious and religious buildings (when cedars were used), for the furniture (e.g., ebony, mahogany) of the nobility, for boats and vehicles. Consideration of their relevance to anthropology, and to the origin of technological developments in different primitive cultures, would satisfy a personal life-long interest. Attention to such a topic is urgently needed now that the development and destruction of land and forests is increasing and wiping out the traces of earlier people to meet the demands of the rapidly enlarging populations of today. The latter represents an even more urgent need. Increasingly, mankind will depend on renewable,resources produced at low energy cost. Forest products are one of these and the greater demands for them will require their growth and utilization with reduced loss and waste.
Book Synopsis Natural Products of Woody Plants by : John W. Rowe
Download or read book Natural Products of Woody Plants written by John W. Rowe and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood as found in trees and bushes was of primary importance to ancient humans in their struggle to control their environment. Subsequent evolution through the Bronze and Iron Ages up to our present technologically advanced society has hardly diminished the importance of wood. Today, its role as a source of paper products, furniture, building materials, and fuel is still of major significance. Wood consists of a mixture of polymers, often referred to as lignocellulose. The cellulose micro fibrils consist of an immensely strong, linear polymer of glucose. They are associated with smaller, more complex polymers composed of various sugars called hemicelluloses. These polysaccharides are embedded in an amorphous phenylpropane polymer, lignin, creating a remarkably strong com posite structure, the lignocellulosic cell wall. Wood also contains materials that are largely extraneous to this lignocellulosic cell wall. These extracellular substances can range from less than 1070 to about 35% of the dry weight of the wood, but the usual range is 2% -10%. Among these components are the mineral constituents, salts of calcium, potassium, sodium, and other metals, particularly those present in the soil where the tree is growing. Some of the extraneous components of wood are too insoluble to be ex tracted by inert solvents and remain to give extractive-free wood its color; very often these are high-molecular-weight polyphenolics.
Book Synopsis Analytical Methods in Wood Chemistry, Pulping, and Papermaking by : Eero Sjöström
Download or read book Analytical Methods in Wood Chemistry, Pulping, and Papermaking written by Eero Sjöström and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: In its broadest sense, and according to the traditional conception, wood chemistry is a comprehensive discipline, ranging from fundamental studies to practical applications. The manifold constituents, located in different morphological regions in the wood, results in an extreme complexity of wood chemistry. Ever more sophisticated endeavors needing fundamental studies and advanced analytical methods are necessary in order to delve deeper into various problems in pulping and papermaking. Gradually, new, improved ana lytical methods, originally developed for research purposes, are currently replacing many of the old "routine" methods in practical applications. Because of the expanse of the subject, an attempt to write a book of this size about analytical methods seems, perhaps, too ambitious. Of course, a whole book series of several volumes would be necessary to cover this topic completely. However, there is undoubtedly a need for a more condensed presentation which does not go into experimental details, but is limited to the basic principles of the analytical methods and illustrates their applica tions. The emphasis is on more advanced and potential methods, and partic ularly on those based on different types of spectroscopy and chromatography.

Book Synopsis Utilization of Residual Forest Biomass by : Pentti Hakkila
Download or read book Utilization of Residual Forest Biomass written by Pentti Hakkila and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: An increase in the demand for wood results in improved recovery and less residual biomass in the forests. Paradoxically, interest in forest residue as a renewable source of raw material seems to be in a reverse ratio to its availability in a certain area. Finland and Sweden are probably more dependent on forestry and forest in dustries than any other developed countries in the world. A sufficiency of raw ma terial for integrated forest industries is vital for the national economy of both countries, and a great deal of attention is being paid to the long-term potential of unutilized biomass left behind in logging operations. Furthermore, since these countries possess no reserves of fossil fuels, and since their per-capita consump tion of primary energy is exceptionally high, they also consider unmerchantable forest biomass a realistic source of indigenous energy. A joint Nordic research project on harvesting and utilization of logging residue was carried out in 1969-1976 under the auspices of the Nordic Research Council on Forest Operations. This fruitful cooperation soon gave rise to related national projects in Sweden, Finland, Norway, and Denmark, stimulating further research and producing practical applications. Concurrently, particularly after the worldwide energy crisis in 1973, research on all aspects of utilization of forest bio mass mushroomed in the United States, Canada, and the Soviet Union. An ex plosive increase occurred in both the number and diversity of biomass studies.

Book Synopsis Plant Polyphenols by : Richard W. Hemingway
Download or read book Plant Polyphenols written by Richard W. Hemingway and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1027 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was developed from the proceedings of the 2nd North American Tan nin Conference held in Houghton, Michigan, June, 1991. The objective of this con ference was to bring together people with a common interest in plant polyphenols and to promote interdisciplinary interactions that will lead to a bet ter understand ing of the importance of these substances. Another objective of this conference was to extend the 'tannin family' by making special efforts to encourage participation by scientists outside the United States, obtain more coverage of the hydrolyzable tannins, and further broaden the scope of coverage from the initial concentration on forestry and forest products. Com parison of the contents of this book with 'Chemistry and Significance of Condensed Tannins' that resulted from the proceedings of the 1st North American Tannin Conference shows the degree that these objectives were met. In developing the second conference, care was taken to assure that this book extends rather than duplicates the coverage of the first conference. Therefore, the two books should be taken together to obtain an up to date coverage of the broad area of chemistry and significance of plant polyphenols. Our thanks go to the authors who so kindly contributed chapters and so pa tiently responded to our requests. We thank the Conference Assistance Staff of Michigan Technological University for their help in planning and conducting the conference.

Book Synopsis Primary Wood Processing by : J. C. F. Walker
Download or read book Primary Wood Processing written by J. C. F. Walker and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 609 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is primarily a general text covering the whole sweep of the forest industries. The over-riding emphasis is on a clear, simple interpretation of the underlying science, demonstrating how such principles apply to processing operations. The book considers the broad question "what is wood?" by looking at the biology, chemistry and physics of wood structure. Wood quality is examined, and explanations are offered on how and why wood quality varies and the implications for processing. Finally, various "industrial processes" are reviewed and interpreted. All chapters have been written by specialists, but the presentation targets a generalist audience.
