Temperature-Dependence of Excess Volume of 1-Alkanol Plus N-Alkane Binary-Systems in Terms of an Association Model with a Flory Contribution Term
The model of associated mixtures proposed recently (A.T. Treszczanowicz and G.C. Benson, Fluid Phase Equilibria, 23 (1985) 117), for the excess volume is used to predict its temperature derivative A(p)E=(partial derivative V(E)/partial derivative T)p for 1-alkanol + alkane mixtures. The model parameters estimated for excess volume are adopted. The model predicts the A(p)E values fairly well. The shape and size of A(p)E are discussed as a result of mutual compensation effects of association, non-specific interactions and free volume contributions.
