Abstract
The thermodynamic properties of the binary mixtures having potential oxygenates, biodiesel, aromatic and aliphatic compounds are of considerable importance to chemical engineers in formulation of motor fuel. In order to study the interactions of oxygenate with fuel components, excess molar enthalpy for 2-propanol (1) + aromatic hydrocarbon (2) mixtures were measured with flow microcalorimeter at 303.15 K. At equimole fraction, excess enthalpy values follow the order as: n-hexane > cyclohexane and 2-propanol > 1-propanol. The data have also been interpreted in terms of graph-theoretical approach and Prigogine-Flory-Patterson (PFP) theory and Flory-Treszczanowicz-Benson association (FTB) model. It has been observed that while Prigogine-Flory-Patterson theory fails to predict the excess enthalpy (HmE) values for these system in the composition range x1 > 0.05, agreement with experimental values is reasonably good in propanol lean region. Flory-Treszczanowicz-Benson (FTB) association model and graphtheoretical approach predict the measured HmE quite well. © 2018 Chemical Publishing Co. All Rights Reserved.
