IHS ESDU Vapour pressures and critical points of liquids. Part 1C: C10 to C24 alkanes. 85002

ESDU 85002 gives vapour pressure data for 30 alkanes. The data were obtained from a critical evaluation of experimental results in the literature, extrapolated by a reliable method into the low pressure region, and fitted by a Wagner equation applying over the full liquid range from the freezing to the critical point. The coefficients of the equation are given for each compound and three tables of vapour pressure are included: in SI units at 5 K intervals, in atmospheres at 5 degree C intervals, in lbf/sq in at 10 degree F intervals. The sources of the data used are listed, and a table gives likely uncertainties in values predicted by the equation that should be allowed for in any critical situation. Critically evaluated data for alkanes with molecules containing 1 to 7 or 8 and 9 carbon atoms will be found respectively in ESDU 84022 or 84028, while notes on the correlation technique are given in ESDU 84021.
