Abstract
The saturated vapor pressures and enthalpies of vaporization of n-pentyl esters of linear С2–С6 dicarboxylic acids are determined by the transpiration method in the temperature range of 309.2–361.2 K. The dependences of enthalpies of vaporization on the number of carbon atoms in the molecule and on the retention indices have been determined. The predictive capabilities of the existing calculation schemes for estimation of enthalpy of vaporization of the studied compounds have been analyzed.
