Download or read book Ball Milling Towards Green Synthesis written by Achim Stolle and published by Royal Society of Chemistry. This book was released on 2014-11-26 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ball milling has emerged as a powerful tool over the past few years for effecting chemical reactions by mechanical energy. Allowing a variety of reactions to occur at ambient temperatures and in solvent-free conditions, ball milling presents a greener route for many chemical processes. Compared to the use of microwave and ultrasound as energy sources for chemical reactions, ball milling is not as familiar to chemists and yet it holds great potential. This book will introduce practicing chemists to the technique and will highlight its importance for green transformations. Current applications of ball milling will be covered in detail as well as its origin, recent developments and future scope, challenges and prospects. Chemical transformations covered include carbon-carbon and carbon-heteroatom bond formation, oxidation by solid oxidants, asymmetric organo-catalytic reactions, dehydrogenative coupling, peptide syntheses and polymeric material syntheses. The book will provide a valuable guide for organic, inorganic and organometallic chemists, material scientists, polymer scientists, reaction engineers and postgraduate students in chemistry.
Download or read book Development and Mechanistic Understanding of Ball Milling as a Sustainable Alternative to Traditional Synthesis written by William C. Shearouse and published by . This book was released on 2012 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: As environmental regulations become more stringent, the industrial chemical community needs methods that are sustainable, yet parallel the modern advances of organic synthesis. We believe we are solving the solution to this global problem through the development of sustainable synthesis that utilizes ball milling. Ball milling, unlike traditional synthetic methods, uses mechanical energy to drive organic reactions and transformations towards completion. Not only are we interested in finding reaction pathways that produce desired organic products in high yields, but also we are interested in understanding the mechanisms and theory of these processes in hopes that we may develop chemistries that have synthetic outcomes that are not attainable under traditional synthetic techniques. As a group, we each target different areas of "known" organic synthesis, in order to develop parallel routes that utilize sustainable, ball milling practices. Ball milling and green chemistry are introduced and described in Chapter 1. This dissertation describes specifically my efforts towards the aforementioned goals. Largely, my efforts focused on the development of sustainable olefination reactions, namely, the Wittig reaction and Horner-Wadsworth-Emmons reactions described in Chapters 3 and 4 respectively. In addition, portions of my dissertation research sought to expand the capability of ball milling reactions through the engineering and development of new ball milling tools. The use of functional resins as purification tools for ball milling reactions, described in Chapter 5, as well as the design and fabrication of vials made from different materials, described in Chapter 2, complete my dissertation research.

Available in PDF, EPUB and Kindle. Book excerpt: Mechanochemical Organic Synthesis is a comprehensive reference that not only synthesizes the current literature but also offers practical protocols that industrial and academic scientists can immediately put to use in their daily work. Increasing interest in green chemistry has led to the development of numerous environmentally-friendly methodologies for the synthesis of organic molecules of interest. Amongst the green methodologies drawing attention, mechanochemistry is emerging as a promising method to circumvent the use of toxic solvents and reagents as well as to increase energy efficiency. The development of synthetic strategies that require less, or the minimal, amount of energy to carry out a specific reaction with optimum productivity is of vital importance for large-scale industrial production. Experimental procedures at room temperature are the mildest reaction conditions (essentially required for many temperature-sensitive organic substrates as a key step in multi-step sequence reactions) and are the core of mechanochemical organic synthesis. This green synthetic method is now emerging in a very progressive manner and until now, there is no book that reviews the recent developments in this area. - Features cutting-edge research in the field of mechanochemical organic synthesis for more sustainable reactions - Integrates advances in green chemistry research into industrial applications and process development - Focuses on designing techniques in organic synthesis directed toward mild reaction conditions - Includes global coverage of mechanochemical synthetic protocols for the generation of organic compounds

Download or read book Environmentally Friendly Synthesis Using High Speed Ball Milling written by Daniel C. Waddell and published by . This book was released on 2012 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, there has been a focused effort towards the development of an environmentallyfriendly America. The field of green chemistry has been born of this ideology. Green chemistryis the reduction or elimination of environmentally hazardous chemicals and chemical processes. The Mack lab attempts to reduce some of these hazards by synthesizing molecules with a solventfree and environmentally benign method known as high speed ball milling (HSBM). In HSBM, reactants are shaken vigorously in a reaction vial and the subsequent mixing and impactsgenerated deliver enough energy to the system to facilitate a chemical reaction. Here, we presentthe succesful incorporation of HSBM into organic synthesis. Acid/base chemistry, the Tischenkoreaction, and enolate chemistry will be described in detail. As we increase our knowledge aboutthe solvent free method of HSBM, we are creating a unique and environmentally friendlytoolbox for organic chemists which will cause a paradigm shift in the way we conduct organicreactions.
Download or read book Toward a PFAS free Future written by Simona A Bălan and published by Royal Society of Chemistry. This book was released on 2023-11-17 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are extensively used in consumer products, despite their high persistence and other hazards. The risks posed by this chemical class to human health and the environment, which are increasingly becoming understood, have triggered regulation and policy changes. However, safer alternatives to these technically effective materials and methods to discover and use those alternatives are still under development. Remediation of PFAS contaminated sites will not solve the growing worldwide pollution, but substitution with safer substances at the formulation and manufacturing phases will at least abate the flow of PFASs into our bodies and environment. Introducing safer alternatives to some of the PFASs of concern used in select industry sectors, this book informs the reader about the processes of chemical hazard and alternatives assessment that can foster innovation. It is a valuable resource for both green chemists and industrial chemists interested in how they can make their products safer without compromising on function.
