This book is an attempt to bring together current knowledge on the role and importance of organic acids in life processes. There are lots of compounds based on the chemical nature of this functional group, which makes this class of molecules to be present in our lives starting with the human body (Krebs cycle - the core of cellular metabolism) to the products we currently use (food, medicines and cosmetics). No overall consensus is sought in this book, and the following chapters are authored by dedicated researchers presenting a diversity of applications and hypotheses concerning organic acids. The five chapters in this book include general information on carboxylic acids and their applications in life sciences (use in organic synthesis, nanotechnology, plant physiology, plant nutrition and soil chemistry).
As the second volume in a comprehensive encyclopedia of organic reactions, this work provides an elaborated description of the experimental methods used for the oxidation of alcohols to acids. It supplies important data on possible interferences from protecting groups and functional groups, as well as on potential side-reactions. This book is a must for anyone involved in the preparation of organic compounds.
Membrane Contactors: Fundamentals, Applications and Potentialities, Volume 11 covers new operations that could be efficiently used to improve the performance of a variety of industrial production cycles in applications ranging from biotechnology to agrofood. This book focuses on the basic "principles of work": required membrane materials and properties; major operating parameters; the importance of module configuration and design and; the performance of membrane contactors in specific processes. The authors' dynamic approach to this subject makes Membrane Contactors: Fundamentals, Applications and Potentialities, Volume 11 the most comprehensive book currently available on all aspects related to the 'membrane contactor world.* Describes new unit operations in process engineering* Covers a wide variety of industrial applications, from biotechnology to agrofood* Applicable to process intensification and sustainable growth strategies
Following the successful and proven concept used in "Bioactive Heterocyclic Compound Classes" by the same editors, this book is the first to present approved pharmaceutical and agrochemical compounds classified by their carboxylic acid functionality in one handy volume. Each of the around 40 chapters describes one or two typical syntheses of a specific compound class and provides concise information on the history of development, mode of action, biological activity and field of application, as well as structure-activity relationships. In addition, similarities and differences between pharmaceuticals and agrochemicals are discussed in the introduction. Written by a team of experts in the field, this is a useful reference for researchers in academia and chemical or pharmaceutical companies working in the field of total synthesis and natural product chemistry, drug development, and crop protection research.
This booklet is designed to bridge the gap between handbooks and technical literature and aims at graduate students or experienced readers. Commercial flow sheeting simulation software is increasingly available and is used in the early steps of process design in industry. As to this, more sophisticated and precise models based on activities instead of concentrations should be used. After an introductory chapter there is in Chapter 2 an intensive discussion of reactive phase equilibria of ionic and non-ionic solutes based on chemical potentials. Chapter 3 introduces to multicomponent diffusion and mass transfer. However, the main focus is on the reactive mass transfer on rigid and mobile surfaces where the interfacial reaction, molecular diffusion and adsorption layers are decisive. The respective extraction of zinc with a cation exchanger and of acetic acid with an anion exchanger is discussed as case studies. Since adsorption layers and surfactants have a major impact on liquid-liquid extraction efficiency, the final chapter reviews several tech niques which make use of polymeric species in an extractive process. A short review is also given on extraction apparatus and the hydrodynamics (hydraulic design, droplet populance balances) of columns. Much of the booklet is based on the PhD works of C. Czapla (2000), G. Modes (2000), H. Klocker (1996), T. Kronberger (1995), M. Marters (2000), M. Roos (2000), M. Traving (2000) and B. Wachter (1996) who I wish to thank for their fruitful contributions.
Organic Chemistry for General Degree Students is written to meet the requirements of the London General Internal examination and degree examinations of a similar standing. It will also provide for the needs of students taking the Part 1 examination for Graduate Membership of the Royal Institute of Chemistry, or the Higher National Certificate, whilst the treatment is such that Ordinary National Certificate courses can be based on the first two volumes Within the limits broadly defined by the syllabus, the aim of this first volume is to provide a concise summary of the important general methods of preparation and properties of the main classes of aliphatic compounds. Due attention is paid to practical considerations with particular reference to important industrial processes. At the same time, the fundamental theoretical principles of organic chemistry are illustrated by the discussion of a selection of the more important reaction mechanisms. Questions and problems are included, designed to test the student's appreciation of the subject and his ability to apply the principles embodied therein. A selection of questions set in the relevant examinations is also included.
