Abstract

The excess molar volumes, VmE, have been calculated from measured values of density over the whole composition range at the temperature 298.15 K and atmospheric pressure for the 11 mixtures \N-methyl-2-pyrrolidone+(methanol or ethanol or propan-1-ol or cyclohexane or cyclooctane 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–Treszczanowicz (FBT) model and the Extended Real Associated Solution (ERAS) theory.
