P−ρ−TData of Liquids: Summarization and Evaluation. 8. Miscellaneous Compounds

Abstract

The published experimental data for 53 compounds (eight amines, eight nitriles, four N-heterocyclic compounds, six nitro compounds, four amides, four other compounds containing C, H, O, and N atoms, six halogenated alcohols, five fluoroethers, and eight miscellaneous compounds) are summarized and reviewed, and the parameters of the Tait equation are given for 49 substances. 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 − ρ(Pref)/ρ(P)}) or, using density data at atmospheric pressure (Pref = 0.1 MPa) or at saturation (Pref = Psat), the liquid densities of the substances over a temperature and pressure range. Experimental values of isothermal compressibility at atmospheric pressure compiled from the literature are also summarized and compared with values calculated from the Tait equation.
