Vapour pressures and enthalpies of vaporization of a series of the linear n-alkyl acetates

Vapour pressures and the molar enthalpies of vaporization Delta H-g(l)m of the linear aliphatic acetates C-8-C-16 have been determined by the transpiration method. Kovat's indices of these compounds were measured by capillary gas-chromatography. A linear correlation of enthalpies of vaporization Delta H-g(l)m at T = 298.15 K of the acetates studied with the Kovat's indices as well as with the number of carbon atoms has been found.
