Описание: Solvents have a major role to play in the environmental and sustainability agenda, and many currently used solvents have to be replaced, either because of regulations or because of increasing demands for safer solvents and produce them in safer way. Some solvents previously advertised as green solvents have to be replaced according to the present regulations, and these are costly and risky operations. This book not only gives data on carefully selected, commercially available, green solvents but it also gives expert advice on how to assess and qualify green solvents. Physical properties are included, as are health and safety considerations (such as carcinogenicity, reproduction/developmental toxicity, flammability) and first aid guidance. Emphasis is given in particular to cost-saving and more efficient replacements for more toxic solvents. . . Detailed information is also given for usage considerations, including outstanding properties, potential substitutes, features and benefits for each solvent and for which products the solvent is recommended.
Описание: This unique thesis discusses the development of conceptually novel and synthetically valuable methods that use visible light photocatalysis. Each chapter addresses a different topic in the emerging field of photocatalysis, which has become an indispensable tool for organic synthesis. Photocatalysis employs environmentally harmless and abundant visible light in the presence of a photosensitizer, and as such offers an attractive alternative to harmful UV light in photo-mediated reactions. This book introduces the novel concept of merging gold catalysis with visible light photocatalysis in a dual catalytic fashion, which demonstrates their compatibility with each other for first time and has inspired the development of various reactions. Moreover, a novel trifluoromethylation method, which combines radical addition chemistry with a polar rearrangement to synthesize valuable fluorinated compounds, is presented, since compounds featuring fluorinated functionality are the subject of increasing attention in pharmaceutical, agrochemical and material research. It also develops an external photocatalyst-free photochemical method for the synthesis of valuable indolizine heterocycles, where the product mediates its own formation. Lastly, it describes the synthesis and characterization of two novel highly porous metal-organic frameworks (MOFs). The comprehensive text is rounded out with illustrations and color figures.

Описание: Use of solvents is increasing in various applications, from cleaning to chemical manufacturing, and solvent selection has a major impact on the costs, health and safety and environmental considerations of any given project. Selecting the ideal solvent can improve economic, environmental and operational performance in processing. Based on the Solvents Database by George Wypych, the Databook of Solvents presents – for the first time – this information in book form for ease of reference. . . More than 300 of the most essential solvents are included, selected by expert George Wypych. Physical properties are included, as are health and safety considerations (such as carcinogenicity, reproduction/developmental toxicity, flammability) and first aid guidance. Emphasis is given in particular to cost-saving and more efficient replacements for more toxic solvents. Detailed information is also given for usage considerations, including outstanding properties, potential substitutes, features and benefits for each solvent and for which products the solvent is recommended.
Описание: This book summarizes the author’s findings on the functional principle of flotation reagents, gathered over the past few decades. The fundamentals of and approaches common to surface chemistry are applied to study the reagents’ structure and performance, as well as their interaction with minerals. In particular, the book establishes the theoretical criteria for collector performance. It also includes the quantum chemistry parameters, steric configuration, HOMO and LUMO surface of various reagents. The book offers a valuable resource for all university graduate students, researchers and R&D engineers in minerals processing and extractive metallurgy who wish to explore innovative reagents and technologies that lead to more energy efficient and environmentally sustainable solutions.

Описание:
The Application of Green Solvents in Separation Processes features a logical progression of a wide range of topics and methods, beginning with an overview of green solvents, covering everything from water and organic solvents, to ionic liquids, switchable solvents, eutectic mixtures, supercritical fluids, gas-expanded solvents, and more.
In addition, the book outlines green extraction techniques, such as green membrane extraction, ultrasound-assisted extraction, and surfactant-mediated extraction techniques. Green sampling and sample preparation techniques are then explored, followed by green analytical separations, including green gas and liquid capillary chromatography, counter current chromatography, supercritical fluid chromatography, capillary electrophoresis, and other electrical separations.
Applications of green chemistry techniques that are relevant for a broad range of scientific and technological areas are covered, including the benefits and challenges associated with their application.
This book reviews and characterises promising single-compound solvents, solvent blends and advanced solvent systems suitable for CO2 capture applications using gas-liquid absorption.
Focusing on energy efficient solvents with minimal adverse environmental impact, the contributions included analyse the major technological advantages, as well as research and development challenges of promising solvents and solvent systems in various sustainable CO2 capture applications.
It provides a valuable source of information for undergraduate and postgraduate students, as well as for chemical engineers and energy specialists.
