Current Project

Physical and Biophysical Chemistry Division (I)


Number: 2000-026-1-100 (continuation of 121/10/87)

Title: Critical compilation of vapour liquid critical properties

Task Group
: Kenneth N. Marsh

Members: D. Ambrose, J.H. Dymond, D.W. Morton, and C. Tsonopoulos

Values of vapour-liquid critical properties are essential in corresponding-states treatments of equilibrium thermodynamic and transport property data. The objective is to review all such measurements for pure organic compounds containing nitrogen, halogen(s), and sulfur and silicon and to recommend values for critical temperature, critical pressure and critical densities, with uncertainties.

The current project is the continuation of project 121/10/87 which has to date, resulted in 7 review papers published in the Journal of Chemical and Engineering Data. These include an introductory survey which covers experimental methods and effects of impurities and decomposition on the results; Normal alkanes; Aromatic hydrocarbons: Aliphatic alkanols; Branched alkanes and cyclo-alkanes; Unsaturated aliphatic hydrocarbons and Oxygen compounds other than alkanols and cycloalkanols.
