Saturated vapor pressures and enthalpies of evaporation of esters of glycerol and lower carboxylic acids

Saturated vapor pressures and enthalpies of evaporation of trisubstituted esters of glycerol and carboxylic acids C1–C5 with normal and branched structure were determined by the transpiration method in the temperature range of 300–371 K. Dependences of enthalpies of evaporation on the number of carbon atoms in a molecule and on the retention indices are established. Prognostic possibilities of existing calculation schemes are analyzed for compounds with three carboxyl groups in a molecule.
