Essentials of Coordination Chemistry

A Simplified Approach with 3D Visuals

 

Academic Press, 2016.

ISBNs 9780128038956

Colección: ScienceDirect

Resumen (en inglés):

Essentials of Coordination Chemistry: A Simplified Approach with 3D Visuals provides an accessible overview of this key, foundational topic in inorganic chemistry. Thoroughly illustrated within the book and supplemented by online 3D images and videos in full color, this valuable resource covers basic fundamentals before exploring more advanced topics of interest.

The work begins with an introduction to the structure, properties, and syntheses of ligands with metal centers, before discussing the variety of isomerism exhibited by coordination compounds, such as structural, geometrical and optical isomerism. As thermodynamics and kinetics provide a gateway to synthesis and reactivity of coordination compounds, the book then describes the determination of stability constants and composition of complexes. Building upon those principles, the resource then explains a wide variety of nucleophilic substitution reactions exhibited by both octahedral and square planar complexes. Finally, the book discusses metal carbonyls and nitrosyls, special classes of compounds that can stabilize zero or even negative formal oxidation states of metal ions. Highlighting preparations, properties, and structures, the text explores the unique type of Metal-Ligand bonding which enable many interesting applications of these compounds.

Thoughtfully organized for academic use, Essentials of Coordination Chemistry: A Simplified Approach with 3D Visuals encourages interactive learning. Advanced undergraduate and graduate students, as well as researchers requiring a full overview and visual understanding of coordination chemistry, will find this book invaluable.

  • Includes valuable visual content through 3D images and videos in full color, available online
  • Provides a valuable introduction to the study of organic and inorganic ligands with metal centers
  • Discusses advanced topics including metal carbonyls and nitrosyls

Extractive Metallurgy of Copper

 

4th ed. Pergamon, 2002.

ISBNs 9780080440293

Colección: ScienceDirect

Resumen (en inglés): This new edition has been extensively revised and updated since the 3rd edition published in 1994. It contains an even greater depth of industrial information, focussing on how copper metal is extracted from ore and scrap, and how this extraction could be made more efficient.

Modern high intensity smelting processes are presented in detail, specifically flash, Contop, Isasmelt, Noranda, Teniente and direct-to-blister smelting. Considerable attention is paid to the control of SO2 emissions and manufacture of H2SO4. Recent developments in electrorefining, particularly stainless steel cathode technology are examined. Leaching, solvent extraction and electrowinning are evaluated together with their impact upon optimizing mineral resource utilization. The book demonstrates how recycling of copper and copper alloy scrap is an important source of copper and copper alloys. Copper quality control is also discussed and the book incorporates an important section on extraction economics.
Each chapter is followed by a summary of concepts previously described and offers suggested further reading and references.

ISBNs 9783038420705 9783038420712

Colección: Directory of Open Access Books

Resumen (en inglés): This special issue contains the first papers of Processes and is intended to highlight a diverse set of topics related to process technology for the chemical, materials, biochemical, pharmaceutical and biomedical industries. To enhance the impact of these industries on society, process innovation that allows large-scale manufacturing is essential for both established and emerging technologies. The scope of this special issue includes, but is not limited to: chemical and biochemical reaction processes: mixing, fluid processing and heat transfer systems; mass transfer, separation and purification processes; integrated process design and scale-up; and process modeling, simulation, optimization and control. We are particularly interested in receiving manuscripts that integrate experimental and theoretical/computational studies as well as contributions from industry. We invite researchers and practitioners from all areas of process technology to submit manuscripts for this important special issue of Processes.

Fermentation and Biochemical Engineering Handbook

Principles, Process Design, and Equipment

 

2nd ed. William Andrew Publishing, 1996.

ISBNs 9780815514077

Colección: ScienceDirect

Resumen (en inglés): This is a well-rounded handbook of fermentation and biochemical engineering presenting techniques for the commercial production of chemicals and pharmaceuticals via fermentation. Emphasis is given to unit operations fermentation, separation, purification, and recovery. Principles, process design, and equipment are detailed. Environment aspects are covered.

The practical aspects of development, design, and operation are stressed. Theory is included to provide the necessary insight for a particular operation. Problems addressed are the collection of pilot data, choice of scale-up parameters, selection of the right piece of equipment, pinpointing of likely trouble spots, and methods of troubleshooting.

The text, written from a practical and operating viewpoint, will assist development, design, engineering and production personnel in the fermentation industry. Contributors were selected based on their industrial background and orientation. The book is illustrated with numerous figures, photographs and schematic diagrams.

Fine Chemicals Manufacture

Technology and Engineering

 

Elsevier Science B.V., 2001.

ISBNs 9780444822024

Colección: ScienceDirect

Resumen (en inglés): The sector of fine chemicals, including pharmaceuticals, agrochemicals, dyes and pigments, fragrances and flavours, intermediates, and performance chemicals is growing fast. For obvious reasons chemistry is a key to the success in developing new processes for fine chemicals. However, as a rule, chemists formulate results of their work as recipes, which usually lack important information for process development. Fine Chemicals Manufacture, Technology and Engineering is intended to show what is needed to make the recipe more useful for process development purposes and to transform the recipe into an industrial process that will be safe, environmentally friendly, and profitable.
The goal of this book is to form a bridge between chemists and specialists of all other branches involved in the scale-up of new processes or modification of existing processes with both a minimum effort and risk and maximum profit when commercializing the process. New techniques for scale-up and optimization of existing processes and improvements in the utilization of process equipment that have been developed in recent years are presented in the book.

Fluidization Dynamics

The formulation and applications of a predictive theory for the fluidized state

 

Butterworth-Heinemann, 2001.

ISBNs 9780750650038

Colección: ScienceDirect

Resumen (en inglés): Fluidization Dynamics has been written for students and engineers who find themselves involved with problems concerning the fluidized state. It presents an analysis that focuses directly on the problem of predicting the fluid dynamic behaviour of a proposed fluidized system for which empirical data is limited or unavailable.




The second objective is to provide a treatment of fluidization dynamics that is readily accessible to the non-specialist. The linear approach adopted in this book, starting with the formulation of predictive expressions for the basic forces that act on a fluidized particle, offers a clear way into the theory. The incorporation of the force terms into the conservation equations for mass and momentum and subsequent applications are presented in a manner that requires only the haziest recollection of elementary fluid-dynamics theory.

The analyses presented in this book represent a body of research that has appeared in numerous publications over the last 20 years. L.G. Gibilaro has taken the opportunity to reorder much of the material in the light of subsequent knowledge, to correct minor errors and inconsistencies and to add detail and clarification where necessary. This material helps to form the basis for university course modules in engineering and applied science at undergraduate and graduate level, as well as focused, post-experienced courses for the process, and allied industries.


· Bridges the gulf between observed behaviour and fluid-dynamic theory
· Clear account of basic theory of fluidization
· Accessible treatment of fluidization analysis
