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

The excess molar enthalpies ( H E) 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-butoxyethan...

Description
Summary:The excess molar enthalpies ( H E) 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 H E is positive. The H E data are interpreted on the basis of possible intermolecular interactions between unlike molecules of the components.
