ESDU 93009
Vapour pressures and critical points of liquids: Aliphatic and cyclic ketones.
Abstract:
(Scanned original)ESDU 93009 presents vapour pressure data for all isomers (26 compounds) of aliphatic ketones up to C7, 13 aliphatic ketones between C8 and C15, mesityl and isomesityl oxides, and cyclo-butanone, -pentanone, -hexanone, -heptanone and -octanone. The data were obtained by a critical evaluation of experimental results in the literature correlated by a method that allows the extrapolation of results in the higher pressure ranges into the low pressure region. The method also enabled correlations to be developed for compounds for which only restricted results were available using correlations for compounds for which a wide range of data existed. The Wagner equation was used over the full liquid range from the melting point to the critical point. The coefficients of the equation are given for each compound and three tables of vapour pressure values calculated using them are included: in SI units at 5 K intervals, in mm of mercury or atmospheres at 10 degree C intervals, in lbf/sq in at 20 degree F intervals. A table also gives the saturation temperature at various specified pressures, and indicates the possible uncertainty in the calculated values. The sources of the data for each compound are included.
