Predicting Excess Enthalpies of Ether and/or Hydrocarbon Binary Mixtures

摘要

Previous applications of the Flory-Patterson theory in the analysis of the excess molar enthalpies at 25 deg C for some binary mixtures composed of ethers, n-alkanes, br-alknes, and cycloalkanes are reviewed. The possibility of correlating the Flory interaction parameters X_(ij) in terms of the acentric factors of the components is examined. For selected ether (1) + n-alkane(2) mixtures, a set of linear relations between X_(12) and the acentric factors of the n-alkanes are reported.
