Book excerpt: In Solvent Effects in Chemistry: Advances in Applications and Research, a critical review of solvent influence on the performance of metal catalysts in the hydrogenation of carbonyl compounds, specifically unsaturated aldehydes, ketones and ketoesters, is provided.Additionally, the effects of solvent on the kinetics and mechanism of different reactions, stability, and sensitivity of the nanostructures are investigated.The uses of a large of variety of solvents varying from non-polar low basic solvents to polar strong basic solvents are discussed, showing that the properties of different solvents strongly influence the product composition of both studied reactions.The effects of solvent on the isomerization of monoterpenes epoxides as α- and β-pinene epoxide, limonene epoxide, verbenol epoxide, and nopol epoxide are explained from molecular and mechanistic points of view.The concluding study explores how heterolytic bond dissociation forms ionic species, while the corresponding homolytic bond dissociation results in the formation of neutral radical species.

Download or read book Organic Solvents written by Eleanor Mullins and published by Nova Science Publishers. This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Biphasic Chemistry and The Solvent Case written by Jean-Philippe Goddard and published by John Wiley & Sons. This book was released on 2020-01-09 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biphasic Chemistry and The Solvent Case examines recent improvements in reaction conditions, in order to affirm the role of chemistry in the sustainable field. This book shows that those who work within the chemistry industry support limits for the use of toxic or flammable solvents, since it reduces the purifications to simple filtrations. Thanks to commercial scavengers, solid phase syntheses are now available to all. Fluorine biphasic catalysis enables extremely efficient catalyst recycling and has a high applicability potential at the industrial level. This book also reviews the many studies that have shown that water is a solvent of choice for most synthetic reactions. Particular traits can be obtained and the effects on thermodynamics make it possible to operate at lower temperatures, thereby achieving energy savings. Finally the great diversity of application of the reactions without solvents is illustrated.
