Book Description
Optically active compounds are gaining ever-increasing importance in organic chemistry, both in the academic and the industrial arenas. The rational synthesis of the growing number of chiral chemicals, drugs, and natural products demands efficient methods for producing these compounds in an enantiomerically, highly pure form. Despite the available alternative techniques, optical resolution via Diastereomeric salt formation remains the most widely used method of preparing pure enantiomers. The CRC Handbook of Optical Resolutions Via Diastereomeric Salt Formation is the first book to exclusively address this important organic chemical process. It provides fast, one-stop access to a wealth of information, including all of the available data on 100 resolving agents, a list of 500 optically active compounds available in bulk along with their suppliers, data on more than 3,500 resolutions, and 4,200 citations. This handbook helps answer virtually any question that may arise during the development of a new resolution process. Which resolving agent and solvent should I use under these conditions? How can I separate the diastereoisomers? How can I optimize a resolution process? How do I determine enantiomeric purity? Which supplier has the resolving agent I need? For a racemate already resolved, what were the resolving agent, solvent, and relevant citation? This is the first book to deal exclusively with all aspects of this important organic chemical process, both theoretical and practical. With an abundance of analyzed examples, this single, authoritative reference provides all of the information you need to perform, develop, and optimize optical resolutions via Diastereomeric salt formation

Book Description
In spite of important advances in asymmetric synthesis, chiral compounds cannot all be obtained in a pure state by asymmetric synthesis. As a result, enantiomer separation remains an important technique for obtaining optically active materials. Although asymmetric synthesis is a once-only procedure, an enantiomer separation process can be repeated until the optically pure sample is obtained. This book discusses several new enantiomer separation methods using modern techniques developed by experts in the field. These methods consist mainly of the following three types: 1) Enantiomer separation by inclusion complexation with a chiral host compound 2) Enantiomer separation using biological methods 3) Enantiomer separation by HPLC chromatography using a column containing a chiral stationary phase. Separation of a racemic compound has been called “optical resolution” or simply “resolution”. Nowadays, the descriptions “enantiomer resolution” or “enantiomer separation” are also commonly used. Accordingly, “Enantiomer Separation” is used in the title of this book. The editor and all chapter contributors hope that this book is helpful for scientists and engineers working in this field.

Book Description
This book highlights the current state-of-the-art regarding the application of applied crystallographic methodologies for understanding, predicting and controlling the transformation from the molecular to crystalline state with the latter exhibiting pre-defined properties. This philosophy is built around the fundamental principles underpinning the three inter-connected themes of Form (what), Formation (how) and Function (why). Topics covered include: molecular and crystal structure, chirality and ferromagnetism, supramolecular assembly, defects and reactivity, morphology and surface energetics. Approaches for preparing crystals and nano-crystals with novel physical, chemical and mechanical properties include: crystallisation, seeding, phase diagrams, polymorphic control, chiral separation, ultrasonic techniques and mechano-chemistry. The vision is realised through examination of a range of advanced analytical characterisation techniques including in-situ studies. The work is underpinned through an unprecedented structural perspective of molecular features, solid-state packing arrangements and surface energetics as well as in-situ studies. This work will be of interest to researchers, industrialists, intellectual property specialists and policy makers interested in the latest developments in the design and supply of advanced high added-value organic solid-form materials and product composites.

Book Description
The field of crystallization holds many challenges, with the physical and chemical complexity of the crystallization process being core to the dynamic nature of the field. Exciting advances are currently being achieved in the areas of nanoparticle formation, product and particle design and methods of particle characterisation. There is also significant progress and innovation in the design, scale-up and control of crystallizers. These key developments are reflected in the session themes of the 14th BIWIC (Bremen International Workshop on Industrial Crystallization) with the technical programme incorporating a wide range of topics, such as; The formation and stabilisation of nano particles; Polymorphs and co-crystals in pharmaceutical preparation; Product and particle design; Kinetics of crystallization and measurement of crystal properties; Freeze, Antisolvent, Reactive and Melt crystallization; and Design, scale-up and control of crystallization processes at the industrial scale.
