Download or read book Green Chemistry written by V.K. Ahluwalia and published by Springer Nature. This book was released on 2021-07-02 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a large number of organic reactions performed under green conditions, which were earlier performed using anhydrous conditions and various volatile organic solvents. The conditions used involve green solvents like water, super critical carbon dioxide, ionic liquids, polymer-supported reagents, polyethylene glycol and perfluorous liquids. A number of reactions have been conducted in solid state without using any solvent. Most of the reactions have been conducted under microwave irradiations and sonication. In large number of reactions, catalysts like phase transfer catalysts, crown ethers and biocatalysts have been used. Providing the protocols that every laboratory should adopt, this book elaborates the principles of green chemistry and discusses the planning and preparations required to convert to green laboratory techniques. It includes applications relevant to practicing researchers, students and environmental chemists. This book is useful for students (graduate and postgraduate), researchers and industry professionals in the area of chemical engineering, chemistry and allied fields.
Book Synopsis Environmental Catalysis by : Vicki H. Grassian
Download or read book Environmental Catalysis written by Vicki H. Grassian and published by CRC Press. This book was released on 2005-05-26 with total page 701 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of environmental interfaces and environmental catalysis is central to finding more effective solutions to air pollution and in understanding of how pollution impacts the natural environment. Encompassing concepts, techniques, and methods, Environmental Catalysis provides a mix of theory, computation, analysis, and synthesis to support the latest applications in biocatalysis, green chemistry, environmental remediation and our understanding of the interaction of pollutants with natural systems. The book focuses on several aspects of environmental catalysis. Surface catalysis of airborne particles - including ice, trace atmospheric gases, aerosolized soot nanoparticles, and mineral dust surfaces - as well as particles in contact with ground water and their role in surface adsorption, surface catalysis, hydrolysis, dissolution, precipitation, oxidation and ozone decomposition is explored. It continues by presenting catalysis as the key technology for treating emissions and reducing waste by-products. The authors review the theory behind catalytic converters and discuss the effectiveness of several catalysts, including zeolites and nanoparticles, in treating emissions, aromatic hydrocarbons, and chemical warfare agents. They also survey the use of biocatalysis in environmental remediation, and industrial processes, particularly in the production of transportation fuels, fine chemicals, and pharmaceuticals. Then the authors explain how enzymes can remove chlorinated organics and metals and how microbes can metabolize toxic chemicals from groundwater. Lastly, they discuss the principles of green chemistry, including the use of environmentally benign solvents, biphasic catalysts, and other alternative solvents to recover and recycle catalysts based on heavy metals. With increasing ground water pollution, increasing particulates in the atmosphere, and the increasing need to remove pollutants from industrial and automotive sources, Environmental Catalysis addresses issues that will be instrumental in current and future environmental challenges we face.

Book Synopsis Environmentally Benign Photocatalysts by : Masakazu Anpo
Download or read book Environmentally Benign Photocatalysts written by Masakazu Anpo and published by Springer Science & Business Media. This book was released on 2010-11-11 with total page 740 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past few decades, mankind has observed an unprecedented and remarkable growth in industry, resulting in a more prosperous lifestyle for peoples of many countries. In developing countries, however, explosive industrial growth is just now beginning to raise the living standards of the people. Most industries, especially in these developing countries, are still powered by the burning of fossil fuels; con- quently, a lack of clean energy resources has caused environmental pollution on an unprecedented large and global scale. Toxic wastes have been relentlessly released into the air and water leading to serious and devastating environmental and health problems while endangering the planet and life itself with the effects of global warming. To address these urgent environmental issues, new catalytic and photocatalytic processes as well as open-atmospheric systems are presently being developed that can operate at room temperature while being totally clean and ef?cient and thus environmentally harmonious. Essential to technologies harnessing the abundant solar energy that reaches the earth are the highly functional photocatalytic proce- es that can utilize not only UV light, but also visible light.

Book Synopsis Eco-friendly Synthesis of Fine Chemicals by : Roberto Ballini
Download or read book Eco-friendly Synthesis of Fine Chemicals written by Roberto Ballini and published by Royal Society of Chemistry. This book was released on 2009 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: During these early years, the chronic toxicological properties of chemicals were often completely unknown and many unwittingly became indispensable tools of the trade. Early pioneers in green chemistry included Trost (who developed the atom economy principle) and Sheldon (who developed the E-Factor). These measures were introduced to encourage the use of more sustainable chemistry and provide some benchmarking data to encourage scientists to aspire to more benign synthesis. Green chemistry is essentially the design of chemical processes and procedures that reduce or eliminate the use, or the generation, of hazardous substances. Green chemistry is a growing area of research and an increasing number of researchers are now involved in this field. The number of publications has dramatically increased and new recognition of advances made is necessary with respect to other research areas.

Book Synopsis Radical and Ion-pairing Strategies in Asymmetric Organocatalysis by : Maxime R Vitale
Download or read book Radical and Ion-pairing Strategies in Asymmetric Organocatalysis written by Maxime R Vitale and published by Elsevier. This book was released on 2017-07-21 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Considering the challenge of sustainability facing our society in the coming decades, catalysis is without any doubt a research area of major importance. In this regard, asymmetric organocatalysis, now considered a pillar of green chemistry, deserves particular attention. The first chapter of this volume examines the topic of asymmetric organocatalysis in light of radical chemistry. Recent important progress in this field has been attained by promoting the formation and harnessing the high reactivity of open-shell intermediates. Merging organocatalysis with radical chemistry has been the key to solving some longstanding bottlenecks, and has also significantly contributed to reinforcing the key role of organocatalysis in asymmetric catalysis. This chapter presents the most significant developments in this area, with a particular focus on asymmetric SOMO- and photoredox-organocatalyzed transformations. Chapter 2 focuses on quaternary ammonium salts (R4N+X-), especially chiral derivatives, and their behavior as unique catalysts in organocatalysis. Forming chiral ion-pairs capable of promoting asymmetric reactions, they also operate as unique “transporters involved in phase transfer catalytic processes between liquid–liquid or liquid–solid systems. Furthermore, they offer unique opportunities when forming cooperative ion-paired entities R4N+X-, allowing a synergistic implication of the counter-ion X- either as Brønsted bases or Lewis bases. Specific design of such chiral catalysts in modern chemistry and better insight into their mode of activation facilitates efficient and unprecedented chemical transformations. This chapter provides an overview of the use of chiral quaternary ammonium salts in organocatalysis, emphasizing both general mechanistic aspects and the scope of this approach. Presents the most significant developments with a particular focus on asymmetric SOMO- and photoredox-organocatalyzed transformations Givies a larger overview of chiral ammonium salts in organocatalysis rather than a specific review dedicated to specialists in this area Affords a historical evolution of this field of research
