摘要
The isobaric binary vapor-liquid equilibrium (VLE) data for the mixture of 2-phenylethanol (2PEA) with 1-phenylethanol (1PEA), 2-phenylpropan-2ol (2P2P), ethylbenzene (ETB), and isopropylbenzene (IPB) is generated at 101.3 kPa. The Fredenslund test and Redlich-Kister area test methods were used to confirm the consistency of the measured VLE experimental data. Subsequently, the data sets are correlated by the nonrandom two-liquid (NRTL) and universal quasi-chemical (UNIQUAC) thermodynamic models, and the binary interaction parameters for the two models were estimated using the Britt-Luecke algorithm and the maximum likelihood objective function. The estimation was found to be good for both the activity coefficient models.
