Compound Myopic Astigmatism

A comprehensive compendium of published property estimation techniques for organic compounds. For scientists and engineers seeking to estimate properties of compounds, this time-saving Handbook brings together in one compact volume a vast array of property estimation methods from more than 2,700 published sources for calculating these and many other properties of organic compounds: Density and molar volume Boiling point Refractive index and molar refraction Melting point Surface tension and parachor Water solubility Viscosity Air/water partition coefficient Vapor pressure Octanol/water partition coefficient Enthalpy of vaporization Soil/water partition coefficient. The property estimation techniques detailed in the Handbook have been chosen for their broad applicability and practical value. The discussion of each estimating technique includes a clear exposition of the technique, including classes of compounds for which it is applicable and critical consideration of its strengths and weaknesses, as well as many worked-out examples demonstrating the technique. The Handbook can be used on its own or in tandem with the Toolkit for Estimating Physicochemical Properties of Organic Compounds, an easy-to-use, Windows(r)-based program that puts rapid estimation routines and flexible search capabilities at the user's fingertips. The Toolkit CD features routines for estimating key properties of organic compounds and a database of property and other data for more than 24,000 organic compounds.

While carbohydrate synthons have received much attention in recent years, the potential pool of new compounds has gone largely untapped. This book removes the obstacles to using many carbohydrate products and derivatives and provides a broad introduction to implementing the organic synthesis of chiral compounds. Unlike any other book on the subject, Carbohydrate Building Blocks features a compendium of compounds that can be prepared from inexpensive materials by following a few easy steps. This exciting new material is presented in pictorial dictionary form to facilitate the easy identification and selection of useful compounds. This invaluable guide places the entire field of carbohydrate building blocks at your fingertips. It also: introduces organic chemists and molecular architects to many new sources of useful raw materials; shows the advantages of using readily available carbohydrates as starting materials for organic synthesis of chemical compounds; points out the best carbohydrates to use, where to find them, and how to acquire them at low cost from commercial sources; describes the most effective methods of converting carbohydrates into usable building blocks; clarifies and updates the largely arcane and confusing nomenclature of carbohydrate compounds; offers time- and cost-saving tips for compound preparation throughout the text; and proposes new ways to improve selection and preparation of desirable compounds. For synthetic organic chemists, for professors and students in organic chemistry, and for anyone in search of starting material for synthesis, this book stands as an indispensable guide, an excellent reference, and a boundless source of ideas for further research.

Meso compound - A Meso compound or meso isomer is a chemical compound with molecules that contain 2 or more asymmetric (chiral) centers but which is optically inactive (or achiral) because it contains an internal plane of symmetry. For example one of the isomers of tartaric acid is a meso compound:

Tetrahedral carbonyl addition compound - A tetrahedral carbonyl addition compound is an organic compound formed by nucleophilic addition to a carbonyl compound such as an aldehyde or ketone. This provides the carbon with four temporary bonds, one of which is broken when the leaving group leaves, and another which is formed by formation of a double bond.

Ionic compound - In chemistry, an ionic compound is a chemical compound in which ions are held together in a lattice structure by ionic bonds. To form an ionic compound, there needs to be at least one metal and one non-metal.

Inclusion compound - In host-guest chemistry an inclusion compound is a complex in which one chemical compound the host forms a cavity which molecules of a second compound the guest are located. If the spaces in the host lattice are enclosed on all sides so that the guest species is ‘trapped’ as in a cage, such compounds are known as clathrates.
