Available in PDF, EPUB and Kindle. Book excerpt: Chemical analysis requires solvents, reagents and energy and generates waste. The main goal of green analytical chemistry is to avoid or reduce the undesirable environmental side effects of chemical analysis, while preserving the classic analytical parameters of accuracy, sensitivity, selectivity and precision. This book portrays the current and changing situation concerning adoption of the principles of green chemistry as applied to analysis. It begins by looking at the advantages of and problems associated with on-site analysis and how analytical techniques can lead to increased productivity, efficiency and accuracy, and thereby reduce the consumption of materials. It then focuses on sample preparation techniques minimising solvent consumption or using alternative solvents, concepts and methods of improving the ‘greenness’ of instrumental analysis where miniaturization is an important part, separation methods from the perspective of green analytical chemistry and chemometrics approaches, which can reduce or can even remove the need for conventional steps in chemical analysis. Aimed at graduates and novices just entering the field, managers of analytical research laboratories, teachers of analytical chemistry and green public policy makers, this title will be a useful addition to any analytical scientist's library.

Available in PDF, EPUB and Kindle. Book excerpt: The World Scientific Reference of Hybrid Materials is a set of 3 volumes, which covers the fascinating area of materials science at the intersection between purely polymeric, organic or inorganic materials. The rapidly developing research on hybrid materials is largely driven by the steadily increasing need of multifunctional materials in various branches of technology. However, much of the research is also driven by the curiosity of the researchers and the long lasting wish to merge the most beneficial properties of the various materials into one. The flexibility of polymers could, for example, be merged with the electronic conductivity of metals or the mechanical resistance of ceramics, which will be of great value for the industries.This reference covers the areas of synthesis of such hybrid materials, which take benefit from each of the consisting ingredients, and overviews some of the emerging applications based on the materials. Much of the current research is still in its infancy, but hybrid materials are already now considered to be the key enabler for important future developments, for example flexible electronics. With this perspective, this reference aims at giving the general public an overview over the topics of relevance in this field, but also attracting new researchers to this intriguing scientific area.

Book excerpt: This work showcases the utility of switchable materials. Included are a switchable room-temperature ionic liquid, a switchable solvent, a switchable heterogeneous catalyst system, and a switchable gel. First, the switchable ionic liquid 2-butyl-1,1,3,3-tetramethylguanidium methylcarbonate is fully investigated. Its use in a complete chemical process (including reaction, separation, reformation, and recycle) is demonstrated with several reactions. Furthermore, its potential use for bitumen separation and purification and SO2 capture/isolation are discussed, and preliminary data is presented. Next, piperylene sulfone (PS), a switchable solvent, is synthesized and fully characterized. Anionic nucleophilic substitution reactions were performed in PS, the products were isolated in high yields, and then the PS was reformed for reuse. Then, we designed an immobilized fluorous microphase system that uses F-MonoPhos to induce high enantioselectivities as a switchable heterogeneous catalyst system. Finally, stable reversible polyethyleimine-CO2 gels have been synthesized with 1-octanol. Our findings indicate that PEI-1200/octanol/CO2 gels have potential as a possible drug carrier matrix for transdermal delivery applications.

Download or read book Homogeneous Hydrogenation written by P.A. Chaloner and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Homogeneous hydrogenation is one of the most thoroughly studied fields of homogeneous catalysis. The results of these studies have proved to be most important for an understanding of the underlying principles of the activation of small molecules by transition metal complexes. During the past three decades homogeneous hydrogenation has found widespread application in organic chemistry, including the production of important pharmaceuticals, especially where a sophisticated degree of selectivity is required. This volume presents a general account of the main principles and applications of homogeneous hydrogenation by transition metal complexes. Special attention is devoted to the mechanisms by which these processes occur, and the role of the recently discovered complexes of molecular hydrogen is described. Sources of hydrogen, other than H2, are also considered (transfer hydrogenation). The latest achievements in highly stereoselective hydrogenations have made possible many new applications in organic synthesis. These applications are documented by giving details of the reduction of important unsaturated substrates (alkenes, alkynes, aldehydes and ketones, nitrocompounds, etc.). Hydrogenation in biphasic and phase transfer catalyzed systems is also described. Finally, a discussion of the biochemical routes of H2 activation highlights the similarities and differences in performing hydrogenation in both natural and synthetic systems. For researchers working in the fields of homogeneous catalysis, especially in areas such as pharmaceuticals, plastics and fine chemicals.

Download or read book Alternating Copolymers written by J.M.G. Cowie and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examination of the early literature attests to the fact that the study of copolymerization was initiated when polymer science was in its infancy. It has continued to grow to a subject of major importance and has been a source of interest to both academic and industrialist alike. The wide spectrum of structures and properties available in the statistical copolymer has made this a fruitful field of exploration, but one particular and more restricted form which has held its own fascination for many is the limiting case of the strictly alternating copolymer. This is formed, in the ideal situation, when two monomers in a reaction mixture add consecutively to create a polymer chain with a regular {ABABAB} structure, irrespective of the monomer feed ratio. When this happens the resulting copolymer will always have the same composition, a feature which can be advantageous but also somewhat restrictive, as the ability to vary the properties is then limited. Within a series entitled Speciality Polymers it seems appropriate then to deal with this subject, particularly as no previous attempt has been made to draw together the various facets of alternating copolymerization into one volume. It also seems timely to present a more unified picture of the subject which will also illustrate the progress made.

Available in PDF, EPUB and Kindle. Book excerpt: Metal-Organic Frameworks (MOFs) are crystalline compounds consisting of rigid organic molecules held together and organized by metal ions or clusters. Special interests in these materials arise from the fact that many are highly porous and can be used for storage of small molecules, for example H2 or CO2. Consequently, the materials are ideal candidates for a wide range of applications including gas storage, separation technologies and catalysis. Potential applications include the storage of hydrogen for fuel-cell cars, and the removal and storage of carbon dioxide in sustainable technical processes. MOFs offer the inorganic chemist and materials scientist a wide range of new synthetic possibilities and open the doors to new and exciting basic research. Metal-Organic Frameworks Materials provides a solid basis for the understanding of MOFs and insights into new inorganic materials structures and properties. The volume also reflects progress that has been made in recent years, presenting a wide range of new applications including state-of-the art developments in the promising technology for alternative fuels. The comprehensive volume investigates structures, symmetry, supramolecular chemistry, surface engineering, recognition, properties, and reactions.

Download or read book The Development of CO2 switchable Technologies for Separation of Organic Compounds written by Sean M. Mercer and published by . This book was released on 2012 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing environmental impact of society has created the need for the modification of current and the implementation of new industrial processes which are less environmentally harmful. However, these new or modified processes must be less material-, time-, and cost-intensive such that they are more economically beneficial than the processes they are to supplant. The described research was inspired by these two ideas and is comprised of two projects, both focused on the creation of recyclable, CO2-switchable methods of separating organic compounds. The development and optimization of switchable water, a CO2-switchable ionic strength aqueous solvent is described. The solvent system, an amine/aqueous mixture, had the ability to switch from low to high ionic strength via the application and removal of CO2. This solvent system was able to achieve salting-out of water-miscible organics in comparable amounts to several inorganic salts typically used for salting-out. The switchable water system was explored for use in several industrial applications. A homogeneous catalysis recycling system was developed for the hydroformylation of styrene. A catalyst was able to be recovered and recycled five times with minimal loss of activity. The use of switchable water to expedite the settling of clay suspensions was also explored. Switchable water, when used as process water did not settle bulk clay solids as quickly as a CO2-only treatment, but did however increase the settling rate of small clay fines resulting in lower turbidities of the supernatant. The solvent could be recovered from settled clay suspensions and recycled up to three times. Finally, efforts towards the realization of CO2-switchable chiral resolving agents are presented. It is hypothesized that chiral nitrogenous bases could be used as switchable resolving agents by forming diastereomeric salt pairs with racemic alcohols via the application of CO2. After separation of the diastereomers, removal of CO2 would afford the resolved alcohol enantiomers and the chiral base. Efforts towards the synthesis of a library of chiral nitrogenous bases and the screening of their reactivity with CO2-treated alcohols are described. Several bases were generated, but the necessary reactivity between the bases and the racemic alcohols in the presence of CO2 was not observed.
