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.
