✦ Synopsis

The excess molar enthalpies H E m have been measured for mixtures of pyrrolidin-2-one with methanol, or ethanol, or propan-1-ol, or butan-1-ol, or pentan-1-ol over the whole composition range at T = 303.15 K. The H E m values are positive for all the mixtures over the whole mole fraction range except for methanol which exhibits a sigmoid curve with a maximum at low mole fraction of pyrrolidin-2-one. The values of H E m increase in the order methanol Q ethanol Q propanol Q butanol Q pentanol. The excess partial molar enthalpies of the components have also been evaluated. The results are interpreted in terms of specific interactions.
