Excess enthalpies of ethyl acetate and butyl acetate with 2-alkoxyethanols at 298.15 K

The excess molar enthalpies (HE) of binary solvent mixtures of ethyl acetate and butyl acetate with 2-alkoxyethanols at 298.15 K have been measured over the entire range of composition with paar 1451 solution calorimeter. The 2-alkoxyethanols are 2-methoxyethanol, 2-ethoxyethanol and 2-butoxyethanol. All the systems are characterised by endothermic mixing over the entire range of composition, for which HE is positive. The HE data are interpreted on the basis of possible intermolecular interactions between unlike molecules of the components.
