<i>P</i>-ρ-<i>T</i> Data of Liquids: Summarization and Evaluation. 6. Nonaromatic Hydrocarbons (C<i>_n</i>, <i>n</i> ≥ 5) except <i>n</i>-Alkanes C₅ to C₁₆

Abstract

The published experimental data for 56 hydrocarbons (22 alkanes, 11 alkenes, 20 cycloalkanes, and 3 cycloalkenes) 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) and compression {1 − ρ(Pref)/ρ(P)}) 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.
