Henry's law constant is important in engineering and environmental calculations. It can be used to determine the fate and transport of chemicals in air and water, and it can also be used in the design of air-stripping columns. An extensive literary review was conducted to compile a database of experimental Henry's law constants. Reported values of each chemical are compared in addition to the methods of measurement. Methods and family trends are considered in order to designate a recommended value for each compound in the database. Existing predictive methods are compared, and experimental and modeling needs are identified.
