Metal Oxide Nanoparticles in Organic Solvents


Book Description

Metal Oxide Nanoparticles in Organic Solvents discusses recent advances in the chemistry involved for the controlled synthesis and assembly of metal oxide nanoparticles, the characterizations required by such nanoobjects, and their size and shape depending properties. In the last few years, a valuable alternative to the well-known aqueous sol-gel processes was developed in the form of nonaqueous solution routes. Metal Oxide Nanoparticles in Organic Solvents reviews and compares surfactant- and solvent-controlled routes, as well as providing an overview of techniques for the characterization of metal oxide nanoparticles, crystallization pathways, the physical properties of metal oxide nanoparticles, their applications in diverse fields of technology, and their assembly into larger nano- and mesostructures. Researchers and postgraduates in the fields of nanomaterials and sol-gel chemistry will appreciate this book’s informative approach to chemical formation mechanisms in relation to metal oxides.

Modern Solvents in Organic Synthesis


Book Description

In recent years the choice of a given solvent for performing a reaction has become increasingly important. More and more, selective reagents are used for chemical transformations and the choice of the solvent may be determining for reaching high reaction rates and high selectivities. The toxicity and recycling considerations have also greatly influenced the nature of the solvents used for industrial reactions. Thus, the development of reactions in water is not only important on the laboratory scale but also for industrial applications. The p- formance of metal-catalyzed reactions in water for example has led to several new hydrogenation or hydroformylation procedures with important industrial applications. The various aspects of organic chemistry in water will be prese- ed in this book. Recently, novel reaction media such as perfluorinated solvents or supercritical carbon dioxide has proven to have unique advantages leading to more practical and more efficient reactions. Especially with perfluorinated solvents, new biphasic catalyses and novel approaches to perform organic reactions have been developed. These aspects will be examined in detail in this volume. Finally, the performance of reactions in the absence of solvents will show practical alternatives for many reactions. More than ever before, the choice of the solvent or the solvent system is ess- tial for realizing many chemical transformations with the highest efficiency. This book tries to cover the more recent and important new solvents or solvent systems for both academic and industrial applications.

Organic Solvents


Book Description

Green Chemistry is a philosophy that has been implemented in different areas of science. Organic solvents allow recovery of bioactive compounds without contaminating the environment, since they are non-petroleum solvents and cheap. This book focuses on the properties, applications and health effects of organic solvents. Chapter One examines the chemistry and food applications of green solvents. Chapter Two analyses the use of green solvent in the extraction of bioactive compounds. Chapter Three gives a thermochemical description of the stabilising/destabilising effect of organic solvent molecules on the stability of model enzyme (bovine pancreatic α-chymotrypsin) to elucidate what intermolecular processes produce the main effect on the stability and functioning of the enzymes at high and low water content in organic liquids. Chapter Four reviews a novel experimental method was proposed to study the stability of enzymes in water-organic mixtures. Chapter Five discusses the metrology of exposure to organic solvents in the shoe industry of Sfax, Tunisia.
