This review is part 11 of a series of contributions by the critical properties group of the previous IUPAC Commission I.2 on Thermodynamics, Subcommittee on Thermodynamic Data and the present IUPAC Project #2000-026-1-100, Critical Compilation of Vapor Liquid Critical Properties, sponsored by the Physical and Biophysical Chemistry Division. It presents all known experimental data for the critical constants of organic compounds containing at least two of the following atoms: B, Halogens (counted as one), N, O, S, and Si. Recommendations are given together with uncertainties. Critical temperatures have been converted, where warranted, to the ITS-90 scale.
