Conversational Computation Method for Fitting the Antoine Equation to Vapor Pressure-Temperature Data

Abstract

A least-squares technique and a search method are combined for determination of the constants of the Antoine equation for vapor pressure data. The method is designed for fitting data that have a relatively constant percentage error rather than a constant absolute error. A conversational FORTRAN program is provided with results of sample runs utilizing data from the open literature. The calculation also provides estimates of heats of vaporization and normal boiling point. Plots of the data are provided automatically through the use of a teleplotter.
