Solvents are ubiquitous throughout the chemical industry and are found in many consumer products. As a result, interest in solvents and their environmental impact has been steadily increasing. However, in order to achieve maximum integration of new green solvents into the relevant chemical sectors, clarification of the social, economic, and environmental implications of solvent substitution are needed. This book explores the solvent life cycle, highlighting the challenges faced at various points, from production, through the supply-chain and downstream use to end-of-life treatment. It also discusses the potential benefits that a green chemistry and bio-based economy approach could bring. The current state-of-the-art of green solvents is evaluated along these lines, in addition to reviewing their applications with an appreciation of sustainability criteria. Providing a critical assessment on emerging solvents and featuring case studies and perspectives from different sectors, this is an important reference for academics and industrialists working with solvents, as well as policy-makers involved in bio-based initiatives.

Smaakmaker uit zee: Ooit was zout peperduur en aanleiding tot oorlogen. Nu kost een kilogram dertig cent, en eten we meer zout dan goed voor ons is. Zonder kunnen we echter niet, een volwassene heeft dagelijks anderhalve gram nodig. Het meeste zout halen we uit de bodem van Twente en Oost-Groningen, waar ooit een binnenzee golfde. Zout is een belangrijke grondstof en hulpstof in de voedingsmiddelen- en chemische industrie. Die maakt er bijvoorbeeld chloor van door zout te ontleden in een membraanelektrolysecel. Natuurwetenschappers bedoelen met zouten een hele groep van stoffen die op een soortgelijke manier zijn samengesteld: zoals soda, kalksteen, gips, bot en bakpoeder. Het zijn meestal vaste stoffen met een kristalstructuur. Ook zijn er vloeibare zouten met bijzondere eigenschappen, ionische vloeistoffen, die chemici lang zagen als curiositeit. Inmiddels fungeren ze als oplosmiddel dat niet verdampt en lang herbruikbaar is. Wereldwijd is een groot tekort aan zoet water en verzilt het land. Veel gewassen kunnen daar slecht tegen. Steeds vaker wordt drinkwater met hulp van (zonne)energie gemaakt uit zeewater. Daar waar zoet en zout water elkaar ontmoeten, valt energie te winnen. Voor Nederland met zijn delta lijkt dat een interessante, duurzame energiebron: blauwe energie. Op de Afsluitdijk is er onlangs een proefcentrale voor opgestart.

After a basic introduction spanning the principles of stereoselective transformations, kinetics and enzyme properties, the different types of reactions are explained. Special techniques, such as the use of enzymes in organic solvents, immobilization techniques and the use of modified enzymes, are also treated. This new edition features an improved didactic style and includes new developments, such as dynamic resolution, stereo-inversion and enantio-convergent processes.

In his highly anticipated sequel to The Elements, Theodore Gray demonstrates how the elements of the periodic table combine to form the molecules that make up our world. Everything physical is made up of the elements and the infinite variety of molecules they form when they combine with each other. In Molecules, Theodore Gray takes the next step in the grand story that began with the periodic table in his best-selling book, The Elements: A Visual Exploration of Every Known Atom in the Universe. Here, he explores through fascinating stories and trademark stunning photography the most interesting, essential, useful, and beautiful of the millions of chemical structures that make up every material in the world. Gray begins with an explanation of how atoms bond to form molecules and compounds, as well as the difference between organic and inorganic chemistry. He then goes on to explore the vast array of materials molecules can create, including: soaps and solvents; goops and oils; rocks and ores; ropes and fibers; painkillers and dangerous drugs; sweeteners; perfumes and stink bombs; colors and pigments; and controversial compounds including asbestos, CFCs, and thimerosal. Big, gorgeous photographs, as well as diagrams of the compounds and their chemical bonds, rendered with never before seen beauty, fill the pages and capture molecules in their various states. As he did in The Elements, Gray shows us molecules as we've never seen them before. It's the perfect book for his loyal fans who've been eager for more and for anyone fascinated with the mysteries of the material world.
