Abstract: Excess molar volumes of {(1-x A)CH 3(CH 2) n-1OH+x ACH 3CN} for n=1, 2, 3 or 4 as a function of composition under atmospheric pressure at 288.15, 293.15, 298.15 and 303.15 K have been used to test the applicability of the Prigogine-Flory-Patterson theory. According to the model, interactional contribution is the most important one to explain the V m E behavior. Good agreement is only achieved for the mixtures containing methanol (C 1) or 1-butanol (C 4). For the mixtures containing ethanol (C 2) and 1-propanol (C 3), which show an S-shaped V m E behavior, the correlation fails. © 2003 Elsevier B.V. All rights reserved.
