Download Heteropolyacids as Highly Efficient and Green Catalysts Applied in Organic Transformations Book in PDF, ePub and Kindle
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

Download Polyoxomolybdates as Green Catalysts for Aerobic Oxidation Book in PDF, ePub and Kindle
Heterogeneously catalyzed selective oxidations of alcohols is a highly topical field. The first chapter of this brief describes the importance of the selective oxidation of alcohols and advantages of heterogeneous catalysts over conventional catalysts, use of environmentally benign oxidants, and the design of selective catalysts by tailoring of polyoxometalates at the molecular level. Chapter 2 describes synthesis, characterization 11-molybdophosphate based supported materials and their use as heterogeneous catalysts for oxidation of alcohols with molecular oxygen under solvent free mild reaction condition. ZrO2, Al2O3, MCM-41 and zeolite Hβ were used as supports. Chapter 3 describes synthesis, characterization of transition metals (Mn, Co, Ni, Cu)- substituted phosphomolybdates and their use as heterogeneous catalysts for oxidation of alcohols with molecular oxygen under solvent free mild reaction condition. Chapter 4 describes conclusive remarks for present catalytic systems.

Download Sulfonic Acid Functionalized Reusable Catalysts in Organic Synthesis Book in PDF, ePub and Kindle
Silica gel as an accessible substrate with high surface area can be modified by propyl S-sulfonic acid. Silica-bonded S-sulfonic acid (SBSSA), silica-bonded N-propyl sulfamic acid (SBNPSA) and silica-bonded N-propylpiperazine sulfamic acid (SBPPSA) as highly efficient heterogeneous solid acid catalysts for the green synthesis of various organic compounds including highly important biological active heterocycles have been developed by many scientists recently. The superior advantage of these heterogeneous catalysts is that they can be recovered and reused several times without the loss of their efficiency. This book will help the reader to understand the preparation and utilization of SBSSA, SBNPSA and SBPPSA as solid heterogeneous catalysts for organic transformations in both theoretical and practical aspects.

Download Clay Mineral Catalysis of Organic Reactions Book in PDF, ePub and Kindle
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.

Download Frontiers of Green Catalytic Selective Oxidations Book in PDF, ePub and Kindle
The demand for novel efficient and environmentally sustainable chemo, regio- and stereoselective catalyst systems for the oxidation of organic substrates is continuously growing in line with toughening economic and environmental constraints. This book addresses these issues; it consists of eleven chapters written by world-recognized experts in green and sustainable oxidation catalysis. The most urgent and challenging topics, in the judgment of the editor, such as green asymmetric epoxidations, sulfoxidatiuons, C–H oxidations; oxidation catalysis by polyoxometalates and oxidations in non-conventional solvents, etc. have been critically reviewed in this book. Both fundamental aspects, such as catalysts design, catalytic properties, nature of catalytically active sites and reaction mechanisms, and practical outlook of the oxidations have been addressed by the authors. The book appeals to a broad readership, particularly graduate students, employees of universities and research organizations, and industrial researchers, particularly those working in the areas of homogeneous oxidation catalysis, asymmetric synthesis, organocatalysis, sustainable catalytic processes and green chemistry, mechanisms of catalytic reactions, synthesis of bioactive compounds, biomimetic chemistry, etc. Konstantin Bryliakov is Leading Researcher at the Boreskov Institute of Catalysis. In 2016, he was elected Honorary Professor of the Russian Academy of Sciences.

Download Glycerine Production and Transformation Book in PDF, ePub and Kindle
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.
