ResumoAn equation for correlating the vapor pressures of pure substances is developed. When this equation is used with reliable thermal data (ΔHv and ΔC0p at 298.15 K) it can be applied for: checking the consistency of vapor pressure data; extrapolation to the low pressure region. It was observed that for homologous series, parameters of the proposed equation vary smoothly. It enables the formulation of a general correlation of vapor pressures of substances belonging to a given homologous series.
