The purpose of this work was to develop an equation to estimate the saturated vapor pressures of organic compounds at ambient temperature. A new equation based on the integrated form of the Clausius-Clapeyron equation was used to estimate the room temperature saturated vapor pressures of 815 organic compounds. It was found to reliably estimate vapor pressures over 15 orders of magnitude with an average absolute error of 0.18 logarithmic units, corresponding to a factor of 1.50.
