IHS ESDU Vapour pressures and critical points of liquids. Part 2B: C7 to C16 alkenes. 85016

ESDU 85016 gives vapour pressure data for 20 alkenes. The data were obtained by a method described in ESDU 84021 involving a critical evaluation of experimental results in the literature, extrapolated by a recent 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 vapour pressure data for a range of alkanes are available in ESDU 84022, 84028 and 85002, and for alkenes with less than six carbon atoms in ESDU 85008.
