摘要

Abstract

Excess molar enthalpies

for the binary mixtures of 2-pentanol with

-alkanes(

-heptane

-octane

and

-nonane) have been determined at three different temperatures

=(293.15

298.15 and 303.15) K and normal atmospheric pressure over the entire composition range using a Calvet microcalorimeter. All mixtures show endothermic mixing with the maximum values of the excess enthalpies occurring in the

-alkane-rich region. The

data are smoothed using Redlich-Kister equation. The applicability of the Treszczanowicz-Benson

ERAS

Renon-Prausnitz and Chen-Bagley models to correlate

of studied mixtures is tested

and the agreement between experimental and theoretical results is satisfactory. Each model includes a self-association equilibrium constant that represents hydrogen bonding and an adjustable parameter that reflects physical interactions.
