This volume gives a detailed account into how renewables can be transformed into value-added products via homogeneous catalysis, especially via transiton metal homogeneous catalysis. The most important catalytic reactions of oleochemicals, isoprenoids, carbohydrates, lignin, proteins and carbon dioxide are described. Special emphasis is placed on carbon-carbon linkage reactions (hydroformylations, dimerisations, telomerisations, metathesis, polymerisations etc.), hydrogenations, oxidations and other important homogeneous reactions (such as isomerisations, hydrosilylations etc.). Also, tandem reactions including isomerising hydroformylations are presented. Wherever possible, the authors have included mechanistic, kinetic, and technical aspects. The reader is therefore given a total overview of the status quo of homogeneous catalysis directed to the most important renewables.
The essential principles of green chemistry are the use of renewable raw materials, highly efficient catalysts and green solvents linked with energy efficiency and process optimization in real-time. Experts from different fields show, how to examine all levels from the molecular elementary steps up to the design and operation of an entire plant for developing novel and efficient production processes.
The completely revised third edition of this four-volume classic is fully updated and now includes such topics as as CH-activation and multicomponent reactions. It describes the most important reaction types, new methods and recent developments in catalysis. The internationally renowned editors and a plethora of international authors (including Nobel laureate R. Noyori) guarantee high quality content throughout the book. A "must read" for everyone in academia and industry working in this field.
Unternehmen befinden sich derzeit in einer Transformation zum nachhaltigeren, vor allem klimaneutralen Wirtschaften. Wesentlich dabei ist die Identifikation von Stellhebeln sowie die technoökonomische und ökologische Bewertung möglicher Maßnahmen. In dieser Arbeit wurde ein Entscheidungsunterstützungssystem entwickelt, mit dem Wertschöpfungsketten klimafreundlicher und zugleich wirtschaftlich konfiguriert werden können. Eine Anwendung erfolgt in Fallstudien zur Automobil- und Zulieferindustrie. - Companies are currently in a transformation towards a more sustainable, especially climate-neutral business. The identification of drivers as well as the techno-economic and ecological evaluation of possible measures are essential in this process. In this work, a decision support system was developed to configure industrial value chains in a more climate-friendly and at the same time economical way. The decision support system is applied in case studies of the automotive and supplier industry.
Technische Chemie für Einsteiger ... komprimiert, klar, lernbar Dieses kompakte Einführungslehrbuch vermittelt die wesentlichen Grundlagen der Technischen Chemie. Es richtet sich in erster Linie an Studierende der Chemie sowie des Chemie- und des Bioingenieurwesens und setzt lediglich Grundkenntnisse in Organischer, Anorganischer und Physikalischer Chemie voraus. Der Stoff ist in vier Teile gegliedert: I. Grundlagen: Der Weg von der Laborchemie über den Technikums- bis zum Produktionsmaßstab — Prozessverbund der chemischen Industrie — Produktstammbäume — Physikalisch-chemische Grundlagen II. Reaktions- und Trenntechnik: Der Reaktionsteil chemischer Prozesse — Ideale und reale Re...
This textbook introduces the industrial production and processing of natural resources. It is divided into six major topics (fats and oils, carbohydrates, lignin, terpenoids, other natural products, biorefinery), which are divided into a total of 20 chapters. Each chapter is self-contained and therefore a compact learning unit, which can be worked on by students in self-study or presented by lecturers. Clear illustrations, flow diagrams, apparatus drawings and photos facilitate the understanding of the subject matter. All chapters end with a succinct summary, the "Take Home Messages". Each chapter is supplemented by ten short test questions, which can be solved quickly after working through the chapter; the answers are at the end of the book. All chapters contain bibliographical references that focus on essential textbooks and reference works. As a prior knowledge, only basic knowledge of chemistry is required.
In Zeiten von Diskussionen über Verbote für Verbrennungsmotoren, der Suche nach neuen Energiekonzepten für die Mobilität von morgen und nicht zuletzt einer intensiveren Diskussion um die Begrenzung der CO2-Emissionen im Zuge des Pariser Klimaschutzabkommens setzt die 4. Tagung der Fuels Joint Research Group einen deutlichen Akzent auf Emissionen und CO2-Ausstoß insgesamt. Der Verbrennungsmotor wird zunächst noch lange Zeit das Rückgrat unserer Mobilität bilden. Es besteht jedoch ein breiter gesellschaftlicher Konsens darüber, dass vermehrt Kraftstoffe aus regenerativen Ressourcen eingesetzt werden sollen und damit der Weg in eine CO2-neutrale Mobilität geebnet wird. Zum anderen kann eine verbesserte Abstimmung von Kraftstoff, Motor, Motoröl und Abgasnachbehandlung wichtige Impulse setzen. Notwendig ist dazu jedoch ein Austausch über fachliche Grenzen hinweg.
This book looks at new ways of tackling the problem of separating reaction products from homogeneous catalytic solutions. The new processes involve low leaching supported catalysts, soluble supports such as polymers and dendrimers and unusual solvents such as water, fluorinated organics, ionic liquids and supercritical fluids. The advantages of the different possibilities are discussed alongside suggestions for further research that will be required for commercialisation. Unlike other books, in addition to the chemistry involved, the book looks at the process design that would be required to bring the new approaches to fruition. Comparisons are given with existing processes that have already...
Over the past decade, much research effort has been devoted to the design and synthesis of new reagents and catalysts that can influence carbon-hydrogen bond activation, mainly because of the prospect that C−H activation could enable the conversion of cheap and abundant alkanes into valuable functionalized organic compounds. Alkane C-H Activation by Single-Site Metal Catalysis presents the current state-of-the-art development in the catalytic systems for the catalytic trans-formations of alkanes under homogeneous conditions. Chapter 1 offers a comprehensive summary of the main discoveries realized so far. Chapter 2 reviews the so-called electrophilic activation, initiated by Shulpín in th...
