Values for the critical temperatures and critical pressures, and coefficients of equations for the vapour pressures of normal alkanes and 1-alkanols are given. They are based on surveys of the available data and estimates of the critical properties of the higher members. The resultant vapour-pressure curves show a progressive change in shape and there are corresponding changes in the coefficients of the equations.

This is part 2 of a series of contributions by the critical properties group of the IUPAC Commission 1.2 on Thermodynamics, Subcommittee on Thermodynamic Data. It presents all known experimental data for the critical constants of normal alkanes, the most extensively investigated class of organic compounds. Data are presented up to C24, and recommendations are given along with uncertainties. Such uncertainties are relatively small for the first 10 normal alkanes, which are stable at the critical point, but are larger for the progressively more unstable Cu-C24 compounds. The critical temperatures have been convertedto

This is part 3 of a series of contributions by the critical properties group of the IUPAC Commission 1.2 on Thermodynamics, Subcommittee on Thermodynamic Data. It presents all known experimental data for the critical constants of aromatic hydrocarbons, which have been divided into four families: normal alkylbenzenes (5 compounds, Ce-Cio); other alkylbenzenes (13 compounds, Cg-C12); polyphenyls (5 compounds, C12-C18); and condensed polycyclics (7 compounds, C9-C14). Recommendations are given together with uncertainties. Critical temperatures have been converted to ITS-90.The aromatic hydrocarbons have been divided into four families: (A) normal alkylbenzenes; (B) other alkylbenzenes; (C) polyphenyls; and (D) condensed polycyclics.Except for benzene, there are relatively few experimental data available for aromatic hydrocarbons, and some of these data, especially for the terphenyls, may be unreliable.The presentation and evaluation of the experimental data follow the guidelines of Ambrose et al. in parts 1 and
