Heteropolyacids as Highly Efficient and Green Catalysts Applied in Organic Transformations introduces heteropolyacids (HPAs) as promising candidates for use as green catalysts. This book initially presents an overview of chemistry of HPAs, including the history of their discovery and applications, systematic classifications, solubility, coordination and binding chemistry, isomerization, stability, redox activity, acidic properties, basicity, skeleton structure, structure types, self-assemblage, surface area, electrochemical behavior, methods of investigation, and characterization. Other sections present and compare the applications of HPAs as homogeneous and heterogeneous catalysts. The book provides readers with a basic-to-advanced range of knowledge on how useful and green HPAs can be used for use as catalysts in organic transformations and even the synthesis of complex organic molecules. - Focuses on applications of HPAs as catalysts, but also includes basic information on HPAs to make it useful to those researchers and scientists whose activities are focused on biochemical analysis, electrochemistry, electrochemical devices, protection of corrosion, medicine and photo-catalyzed reactions - Includes a subdivision devoted to HPA-catalyzed multicomponent reactions for the synthesis of some biologically active compounds via a double-green strategy - Illustrates reactions with approximately 100 chemical reaction schemes to aid understanding
The book provides insight into the working of clays and clay minerals in speeding up a variety of organic reactions. Clay minerals are known to have a large propensity for taking up organic molecules and can catalyse numerous organic reactions due to fine particle size, extensive surface area, layer structure, and peculiar charge characteristics. They can be used as heterogeneous catalysts and catalyst carriers of organic reactions because they are non-corrosive, easy to separate from the reaction mixture, and reusable. Clays and clay minerals have an advantage over other solid acids as they are abundant, inexpensive, and non-polluting.

The increase in the amount of glycerin in the market is a burden for all producers, especially those operating in the biodiesel sector: reuse options are in fact limited for the management of this by-product. Glycerol enhancement has therefore become a priority to improve the sustainability of the biodiesel industry. Nevertheless, the multifunctionality of glycerol makes it a promising precursor for different types of production (fuel/biofuel, chemical products). This conversion has therefore become a subject of multifaceted research that requires an exchange of knowledge across many sectors. In this book, different disciplines (chemistry, biology, engineering, etc.) have been taken into consideration to propose an interdisciplinary point of view on different aspects.
Heterogeneous Catalysis in Sustainable Synthesis is a practical guide to the use of solid catalysts in synthetic chemistry that focuses on environmentally benign applications. Collating essential information on solid catalysts into a single volume, it reveals how the efficient use of heterogeneous catalysts in synthetic chemistry can support sustainable applications. Beginning with a review of the fundamentals of heterogeneous catalytic synthesis, the book then explores the basic concepts of heterogeneous catalytic reactions from adsorption to catalyst poisons, the use of non-traditional activation methods, recommended solvents, the major types of both metal and non-metal solid catalysts, and applications of these catalysts in sustainable synthesis. Based on the extensive experience of its expert author, this book aims to encourage and support synthetic chemists in using solid catalysts in their own work, while also highlighting the important link between heterogeneous catalysis and sustainability to all those interested. - Combines foundational knowledge with a focus on practical applications - Organizes information by reaction type, allowing readers to easily find examples of how to carry out specific reaction types with solid catalysts - Highlights emerging areas such as nanoparticle catalysis and metal-organic framework (MOF) based catalysts
