ABSTRACT

Excess molar enthalpies (HE) measured at 298.15K for the systems: 1-propanol + 1-octene, 1-butanol + 1-octene, 1-hexanol + 1-octene, 1- octanol + 1-octene and 1-decanol + 1-octene are reported. In this series of mixtures the HE values are positive in the whole concentration range. The HE curves are asymmetric and their values decrease with increasing chain length of 1-alkanol molecule. Two versions (with (I) and without (II) cross-association) of the extended real associated solution (ERAS) model and Treszczanowicz Benson (TB) model have been applied to describe experimental HE data and literature excess molar volume (VE) data for these mixtures. This paper points to the weak hydrogen bonds between 1-alkanol hydroxyl and 1-alkene vinyl groups.
