Abstract
The excess molar volumes, V-m(E), have been calculated from measured v alues of density over the whole composition range at the temperature 2 98.15 K and atmospheric pressure for the 11 mixtures {N-methyl-2-pyrro lidone + (methanol or ethanol or propan-1-ol or cyclohexane or cyclooc tane or cyclohexene or benzene or 1-hexene or 1-octene or 1-hexyne or 1-octyne)}. The results are discussed in terms of the hydrogen bonding and other intermolecular associations. The experimental results have been correlated and compared with the results from Flory-Benson-Treszc zanowicz (FBT) model and the Extended Real Associated Solution (ERAS) theory.
