Polymers as Aids in Organic Chemistry covers the broad classifications and application of polymers in organic chemistry. This book is organized into 15 chapters that focus on the transformation of polymers and their role in other reagents that must be easily separated from their final product. After a brief introduction to polymer chemistry, the book presents a tabulation of the various types of polymers that have been used and the methods for their characterization. It then discusses the use of polymers as supports in peptide, oligonucleotide, and oligosaccharide chemistry; in peptide sequencing; in monofunctionalized difunctional compounds preparation, as aids in asymmetric syntheses; and as trapping agents in the determination of reaction intermediates. The subsequent chapters describe the use of polymers as catalysts, with particular emphasis on transition metals immobilized in the polymer matrix and used as catalysts. The concluding chapters examine polymer-immobilized compounds, enzymes, and whole cells that have been used to carry out a large number of reaction, most of which impinge on the area of organic chemistry. Polymer scientists and researchers and organic chemists will find this book invaluable.

Although the title of this book is Paper Chemistry, it should be considered as a text about the chemistry of the formation of paper from aqueous suspensions of fibre and other additives, rather than as a book about the chemistry of the raw material itself. It is the subject of what papermakers call wet-end chemistry. There are many other excellent texts on the chemistry of cellulose and apart from one chapter on the accessibility of cellulose, the subject is not addressed here. Neither does the book deal with the chemistry of pulp preparation (from wood, from other plant sources or from recycled fibres), for there are also many excellent texts on this subject. The first edition of this book was a great success and soon became established as one of the Bibles of the industry. Its achievement then was to collect the considerable advances in understanding which had been made in the chemistry of papermaking in previous years, and provide, for the first time, a sound physico chemical basis of the subject. This new edition has been thoroughly updated with much new material added. The formation of paper is a continuous filtration process in which cellulosic fibres are formed into a network which is then pressed and dried. The important chemistry involved in this process is firstly the retention of col loidal material during filtration and secondly the modification of fibre and sheet properties so as to widen the scope for the use of paper and board products.

Ionic polymers are present almost everywhere in the world, biological systems being the most important reservoir of ionic polymers such as nucleic acids, and many proteins, alginic acid and so on. Artificial ionic polymers derived from natural polymers such as chitin, cellulose or starch, by adequate chemical transformations, and a multitude of synthetic ionic polymers are generated in the laboratory. They can contain ionic or ionisable groups. Ionic polymers, either artificial or synthetic, have a multitude of applications such as: stabilisation or destabilisation of dispersions, thickening of solutions, oil recovery aids, water purification, corrosion inhibitors, soil conditioners, anti-static agents, additives in cosmetics and foods, surface modification, and so forth. Solid ionic hybrid materials found applications such as polymer electrolytes or substrates for the organic synthesis in solid phase. Many books and article reviews were dedicated to this wide class of polymers but the permanent diversification of their structures and applications ask for new and updated overviews on this field. Therefore, this book reports updated information from literature as well as original contributions in the field of ionic (co)polymers and hybrids, mainly on the applications of ionic polymers and hybrids such as: self-assembled multi-layers, ionic polymers containing azobenzene chromophore, phase separation processes, chelating ion exchangers, polymer electrolytes, functionalised solid surfaces and ionic hybrid hydrogels.

The Impact Of Chemical Sequencing On Filtration Performance

The primary objective of this research was to understand the impact of chemical sequencing and coagulation pH/zeta potential on filtration performance. The secondary goal was to determine effective coagulation processes in terms of pH, zeta potential, and coagulant dose for treating challenging (i.e., runoff-type) raw waters. The following are highlights from this project: Use of high coagulation pH (approximately 7.5) provided more consistent filtration performance over a wider range of coagulation conditions than lower pH levels. Because higher pH significantly increases the optimum zeta potential range for filtration, a practical implication of this result is that use of a high coagulation pH process may be the most effective short-term treatment strategy for rapidly changing, runoff-type waters containing low alkalinity and high NOM levels. The photometric dispersion analyzer (PDA) appears to be a useful alternative to jar tests for determining optimum coagulant doses and quickly evaluating different coagulation scenarios.
