This is a simple class definition for an Antoine object to facilitate computation of pure component saturation temperatures and pressures. An object corresponding to a pure component is instantiated by specifying the Antoine parameters. Methods include the computation of saturation pressure, saturation temperature, and plotting.
Sample data is included for a small number of compounds. A search method is included to facilitate search the NIST Chemistry Webbook for Antoine parameters for other compounds.

An extensive tutorial demonstrates the use of Antoine's equation for vapor-liquid equilibrium calculations. Examples include bubble point and dew point calculations, the construction of binary Txy and xy diagrams, and the solution of isothermal flash problems.

This was developed for use in introductory courses in Chemical Engineering.
