The coefficients given in the table below allow to calculate the saturation pressure of the pure substances listed, in mmHg, from the temperature in degree celsius. They are parameters for a modelisation of the saturation pressure as a function of the temperature following an Antoine Law.
Antoine equation - Wikipedia
The Antoine equation is a class of semi-empirical correlations describing the relation between vapor pressure and temperature for pure substances. The Antoine equation is derived from the Clausius–Clapeyron relation. The equation was presented in 1888 by the French engineer Louis Charles Antoine (1825–1897). [1]
Psat for benzene comes out very close to 760 mm Hg at 80.1 degC, which is the normal boiling point of benzene. Psat for toluene comes out very close to 760 mm Hg at 110.6 degC, which is the normal boiling point of toluene. Thus, the Matlab session carries out a check on the Antoine’s equations for benzene and toluene. How very nice!

2023年1月26日 · First, we need to convert the base-10 logarithm to a natural logarithm. The conversion can be done using the relation log₁₀(x) = ln(x)/ln(10). Thus, the Antoine equation becomes ln Psat/(torr) = (a ln(10)) - (b ln(10))t/°C + (c ln(10)). Then, we have to convert the pressure from torr to kPa and the temperature from Celsius to Kelvin.
Vapor Pressure Estimates – Using Antoine Equation
One way to estimate the vapor pressure of a given chemical compound is to use the Antoine Equation. The table below provides reference data on Antoine equation coefficients that has been published in the NIST Chemistry WebBook for a variety of common chemicals.

2016年1月1日 · The Antoine equation, which solves this problem for pure components, is due to a French engineer (Louis Charles Antoine, 1825–1897) and was first published in “Annales de Physique et de Chimie” in 1891 (Antoine 1891). Antoine introduced an equation able to predict the vapor pressure of pure liquids (vaporization) and solids (sublimation).
