VAPOR-LIQUID CRITICAL PROPERTIES OF ELEMENTS AND COMPOUNDS .6. UNSATURATED ALIPHATIC-HYDROCARBONS

This is part 6 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 cr itical constants of unsaturated aliphatic hydrocarbons, which have bee n divided into five families: linear alk-1-enes (10 compounds, C-2 to C-12); other alkenes (8 compounds, C-4 to C-8); alkadienes (3 compound s, C-3 to C-6); terpenes (3 C-10 compounds); and alkynes (3 compounds, C-2 to C-4). Recommendations are given together with uncertainties. C ritical temperatures have been converted to ITS-90.
