Predicting excess enthalpies of ether and/or hydrocarbon binary mixtures

Previous applications of the Flory-Patterson theory in the analysis of the excess molar enthalpies at 25 degrees C for some binary mixtures composed o f ethers, n-alkanes, br-alknes, and cycloalkanes are reviewed. The possibil ity of correlating the Flory interaction parameters X-ij in terms of the ac entric factors of the components is examined. For selected ether(1) + n-alk ane(2) mixtures, a set of linear relations between X-12 and the acentric fa ctors of the n-alkanes are reported.
