This book was released on 2012 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Con el transcurso del tiempo la catálisis ha adquirido ribetes de ciencia multidisciplinaria con relevantes aplicaciones en un amplio conjunto de industrias que involucran una gran variedad de productos químicos. Una de las aplicaciones más relevantes de esta ciencia corresponde a las reacciones de hidrogenación, las que permiten importantes interconversiones de grupos funcionales. El complejo de Wilkinson, [RhCl(PPh3)3], fue uno de los primeros catalizadores homogéneos empleados con éxito en este tipo de reacciones, pero debido a la dificultad típica de estos sistemas, esto es la separación de los productos finales y del catalizador para su reutilización, se consideró importante desarrollar diversas alternativas de anclaje del complejo en soportes sólidos. En virtud de lo expuesto, en el presente trabajo se muestran y analizan resultados acerca del comportamiento catalítico del complejo de Wilkinson en reacciones de hidrogenación de: ciclohexeno, 1-heptino, 1-octeno, norbornadieno entre otros, tanto en fase homogénea como heterogénea usando como soportes: gama-alumina, diferentes tipos de carbones activados (RX3 y A2-Na) y bentonita, en condiciones suaves de presión y temperatura.

Book excerpt: La esencia histórica de la arquitectura colonial es algo que perdura a lo largo de varios siglos. Popayán se inicia con ella, pero se desgaja por un acontecimiento que divide su vida en dos: el antes y el después del terremoto del 2 de febrero de 1736. Sin embargo, los cambios no son drásticos, sino evolutivos, ya que se parte de las circunstancias socio-económicas y culturales que le impone el momento para su reconstrucción. El pensamiento europeo de la época aporta conceptos importantes, pero estos tienen relación más directa con lo humanístico que con lo civil. De ahí que el Barroco, de vieja data en Europa entonces, no tiene en la Nueva Granada la acogida y el desarrollo que presenta en otros países como México y Perú, lo cual repercute también a nivel local, en la medida en que sus alcances no llegan sino a ejercer una limitada influencia en el resurgimiento de Popayán, en cuanto su radio de acción se focaliza fundamentalmente en la valiosa talla de retablos y altares de algunos templos, así como en la pintura y la escultura del siglo XVIII, especialmente en las de tipo religioso. Dentro de ese marco histórico, las creaciones arquitectónicas locales de mayor trascendencia se producen en la segunda mitad del siglo XVIII y en el siglo XIX. De manera especial, cuando se introducen en la ciudad tendencias arquitectónicas que rayan en lo neoclásico, pero con una visión quizás muy particular, casi local. No obstante, aún se descubren latentes muchas de aquellas características tipológicas de la arquitectura payanesa que constituyen su herencia cultural mudéjar, aunadas a algunas variaciones de tipo formal y funcional, manifestadas en la implantación de ciertos principios y detalles que, aunque los caracterizan, el fondo respetan la planitud básica mudéjar.

Download or read book Homogeneous Catalysis written by Sumit Bhaduri and published by John Wiley & Sons. This book was released on 2014-09-08 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade, the area of homogeneous catalysis with transition metal has grown in great scientific interest and technological promise, with research in this area earning three Nobel Prizes and filing thousands of patents relating to metallocene and non-metallocene single site catalysts, asymmetric catalysis, carbon-carbon bond forming metathesis and cross coupling reactions. This text explains these new developments in a unified, cogent, and comprehensible manner while also detailing earlier discoveries and the fundamentals of homogeneous catalysis. Serving as a self-study guide for students and all chemists seeking to gain entry into this field, it can also be used by experienced researchers from both academia and industry for referring to leading state of the art review articles and patents, and also as a quick self-study manual in an area that is outside their immediate expertise. The book features: • Topics including renewable feed stocks (biofuel, glycerol), carbon dioxide based processes (polycarbonates), fluorous solvents, ionic liquid, hydroformylation, polymerization, oxidation, asymmetric catalysis, and more • Basic principles of organometallic chemistry, homogeneous catalysis, and relevant technological issues • Problems and answers, industrial applications (case studies), and examples from proven industrial processes with clear discussions on environmental and techno-commercial issues • Extensive references to cutting edge research with application potential and leading patents • Tables and illustrations to help explain difficult concepts

Download or read book The Investigation of Organic Reactions and Their Mechanisms written by Howard Maskill and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: A range of alternative mechanisms can usually be postulated for most organic chemical reactions, and identification of the most likely requires detailed investigation. Investigation of Organic Reactions and their Mechanisms will serve as a guide for the trained chemist who needs to characterise an organic chemical reaction and investigate its mechanism, but who is not an expert in physical organic chemistry. Such an investigation will lead to an understanding of which bonds are broken, which are made, and the order in which these processes happen. This information and knowledge of the associated kinetic and thermodynamic parameters are central to the development of safe, efficient, and profitable industrial chemical processes, and to extending the synthetic utility of new chemical reactions in chemical and pharmaceutical manufacturing, and academic environments. Written as a coherent account of the principal methods currently used in mechanistic investigations, at a level accessible to academic researchers and graduate chemists in industry, the book is highly practical in approach. The contributing authors, an international group of expert practitioners of the techniques covered, illustrate their contributions by examples from their own research and from the relevant wider chemical literature. The book covers basic aspects such as product analysis, kinetics, catalysis, and investigation of reactive intermediates. It also includes material on significant recent developments, e.g. computational chemistry, calorimetry, and electrochemistry, in addition to topics of high current industrial relevance, e.g. reactions in multiphase systems, and synthetically useful reactions involving free radicals and catalysis by organometallic compounds.

This book was released on 2014-08-29 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploring and highlighting the new horizons in the studies of reaction mechanisms that open joint application of experimental studies and theoretical calculations is the goal of this book. The latest insights and developments in the mechanistic studies of organometallic reactions and catalytic processes are presented and reviewed. The book adopts a unique approach, exemplifying how to use experiments, spectroscopy measurements, and computational methods to reveal reaction pathways and molecular structures of catalysts, rather than concentrating solely on one discipline. The result is a deeper understanding of the underlying reaction mechanism and correlation between molecular structure and reactivity. The contributions represent a wealth of first-hand information from renowned experts working in these disciplines, covering such topics as activation of small molecules, C-C and C-Heteroatom bonds formation, cross-coupling reactions, carbon dioxide converison, homogeneous and heterogeneous transition metal catalysis and metal-graphene systems. With the knowledge gained, the reader will be able to improve existing reaction protocols and rationally design more efficient catalysts or selective reactions. An indispensable source of information for synthetic, analytical, and theoretical chemists in academia and industry.

Download or read book Classical Thermodynamics of Non-Electrolyte Solutions written by H. C. Van Ness and published by Elsevier. This book was released on 2013-10-22 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Classical Thermodynamics of Non-Electrolyte Solutions covers the historical development of classical thermodynamics that concerns the properties of vapor and liquid solutions of non-electrolytes. Classical thermodynamics is a network of equations, developed through the formal logic of mathematics from a very few fundamental postulates and leading to a great variety of useful deductions. This book is composed of seven chapters and begins with discussions on the fundamentals of thermodynamics and the thermodynamic properties of fluids. The succeeding chapter presents the equations of state for the calculation of the thermodynamic behavior of constant-composition fluids, both liquid and gaseous. These topics are followed by surveys of the mixing of pure materials to form a solution under conditions of constant temperature and pressure. The discussion then shifts to general equations for calculation of partial molal properties of homogeneous binary systems. The last chapter considers the approach to equilibrium of systems within which composition changes are brought about either by mass transfer between phases or by chemical reaction within a phase, or by both.
