ABSTRACT

The vapor liquid equilibrium (VLE) at the constant pressure of p/kPa = 101.3 has been determined for the binary mixtures of ethenyl acetate with both methanol and butan-1-ol. The consistency of the data was checked with the Wisniak L W test, and the data were found to be consistent. The experimental data were also satisfactorily adjusted to nonrandom two-liquid (NRTL) and universal quasichemical (UNIQUAC) activity coefficient models, as well as to Peng Robinson and perturbed-chain statistical associating fluid theory (PC-SAFT) equations of state, with the aim of obtaining the binary interaction parameters of both mixtures. With these parameters, the VLE of both mixtures can be accurately predicted, which includes the azeotropic point of the ethenyl acetate + methanol pair. The PC-SAFT and Peng Robinson equations of state were also employed as purely predictive.
