P−ρ−TData of Liquids: Summarization and Evaluation. 5. Aromatic Hydrocarbons

Abstract

The published experimental data for 28 aromatic hydrocarbons are summarized and reviewed, and the parameters of the Tait equation are given. This equation allows the calculation of smoothed values of either the volume ratio, V(P)/V(Pref), and related properties (relative density, ρ(P)/ρ(Pref), compression, {1 − V(P)/V(Pref)}), or, using density data at atmospheric pressure (Pref = 0.1 MPa) or at saturation (Pref = Psat), the liquid density of the substances over a temperature and pressure range. A comparison of isothermal compressibilities calculated from the Tait equation with available data at P = 0.1 MPa from the literature is also presented.
