EXCESS MOLAR VOLUMES OF BINARY-MIXTURES CONTAINING A METHYL-ESTER (ETHANOATE TO TETRADECANOATE) WITH ODD N-ALKANES AT 298.15-K

Molar excess volumes of several methyl esters (from ethanoate to tetra decanoate) with five odd n-alkanes (from pentane to tridecane) were de termined at 298.15 K and atmospheric pressure from the experimental de nsities and correlated by a suitable equation. The results for V-E are compared with those found in the literature and discussed in terms of the interactions between the groups intervening in the mixtures using the Flory and Nitta-Chao models. Only the Nitta-Chao model gives acce ptable agreement with experiment when V-E > 0.
