Vapor Density

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.

The Rapid Guide offers - in alphabetical order - detailed profiles of all 189 elements and compounds determined to be hazardous air pollutants by the 1990 Amendments to the Clean Air Act. The profile for each pollutant includes fundamental identification data (CAS number, molecular formula, formula weight, synonyms); uses (primarily in the manufacture of chemicals and as a component in the manufacturing process); physical properties (such as boiling point, density, vapor pressures, color); chemical properties (such as air/water reactivity, reactivity with skin or metal, flash point, heat of combustion); health risks, including toxic exposure guidelines, toxicity data, and acute and chronic risks; hazard risks - the substance's potential for accidents, fires, explosions, corrosion, and chemical incompatibility; exposure routes tracking the activities, environment, sources, and occupations that tend to lead to exposure; regulatory status, listing the primary laws and citations of regulated chemicals; and important additional information on symptoms, first aid, firefighting methods, protective equipment, and safe storage. Based on the latest available data, Rapid Guide to Hazardous Air Pollutants is a valuable resource for industrial hygienists, emergency response personnel, health and safety managers, environmental and chemical engineers, scientists, chemical manufacturers, and students in environmental programs.

Critical point (chemistry) - In chemistry and condensed matter physics, a critical point, also called a critical state, specifies the conditions (temperature, pressure) at which the liquid state of the matter ceases to exist. As a liquid is heated, its density decreases while the pressure and density of the vapor being formed increases.

Saturation vapor pressure - The saturation vapor pressure is the vapor pressure of water vapor when air is saturated with water vapor. It is the vapor pressure usually found over liquid water, and is a dynamic equilibrium where the rate of condensation of water equals the rate of evaporation of water.

Nuclear density - Nuclear density is the density of the nucleus of an atom, about 10^18 kg/mÂ³; neutron stars reach this density. Nuclear density is often applied to situations where very high, or nuclear densities occur.

Relative density - Relative density (also known as specific gravity) is a measure of the density of a material. It is dimensionless, equal to the density of the material divided by the density of water (or, sometimes used for gases, of air).
