The use of saturated vapor pressure at standard temperature in correlations of physicochemical properties

摘要

The saturated vapor pressure (p_st) at the standard temperature can be a useful descriptor for correlations of physicochemical properties. Regression analysis of the standard heats of vaporization H_st of organic compounds, boiling temperatures T_b at the standard pressure, and the heats of vaporization at boiling temperature H_vb using the logp_st and (logp_st)~2 values as descriptors in combination with solvatochromic descriptors provided the regressions describing these properties for many organic compounds.
