摘要/Abstract

摘要： The vapor-liquid equilibriumof binarymixtures of propyl acetate, butyl acetate and isobutyl acetate withmethanol has been determined at a constant pressure of 0.6 MPa. Results have been modeledwith the Peng-Robinson equation, a traditional cubic equation of state widely employed in chemical industries, as well as with the perturbed-chain statistical associating fluid PC-SAFT theory of Gross-Sadowski. By correlation of the binary interaction parameters of these equations, the measured vapor-liquid equilibrium data can be accurately predicted. Thus, thiswork shows that thesemodels are able to represent the experimental data for systemswith associating compounds via hydrogen bonding.
