In short, verify the VaporCalc and AntoineVP applications results against an independent source.
Data source:
The Antoine coefficients (A, B and C) are derived, with permission, from “The Yaws Handbook of Vapor Pressure (Antoine Coefficients)”, Carl Y. Yaws, Second Edition (2015), Gulf Professional Publishing, https://doi.org/10.1016/C2014-0-03590-3.
Vapor pressures are calculated using the semi-emperical, Antoine equation: log₁₀(p) = A – B/(C+T),
where A, B and C are the Antoine coefficients, T is the temperature in Celsius, and pressure is in units of millimeters of Mercury (mmHg and Torr are equivalent units). The Antoine equation is only accurate over a specified temperature range.
Confidence levels: The Yaws book provides confidence levels for each chemical. Chemicals with a code of 1 (high confidence) are based on experimental data. A code of 2 (medium confidence) indicates an estimate. The estimates with a code of 3 (low confidence) should be considered rough approximations. For those substances that undergo decomposition (such as nitro compounds with explosive decomposition and very large compounds with thermal decomposition) prior to attaining the boiling point temperature, the boiling point temperature is a hypothetical value.
