Isobaric Vapor–Liquid Equilibria for Binary Mixtures of 2-Phenylethanol with 1-Phenylethanol, 2-Phenylpropan-2-ol, Ethylbenzene, and Isopropylbenzene at 101.3 kPa

Abstract

The isobaric binary vapor–liquid equilibrium (VLE) data for the mixture of 2-phenylethanol (2PEA) with 1-phenylethanol (1PEA), 2-phenylpropan-2-ol (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.

Kinetics of One-Pot Regioselective Cohydrogenation of Styrene Oxide and Aryl Alkenes: A Step toward Sustainable Development of a Novel Integrated Process for 2-Phenylethanol Production

“…The binary systems of STOX + 1PEA and STOX + 2P2P are close-boiling mixtures. 33 In order to avoid using energy-intensive distillation schemes to separate STOX and then hydrogenating STOX to produce 2PEA, novel reaction-separation networks are proposed for manufacturing 2PEA using a scheme wherein a hydrogenated mixture can be subjected to distillation (see Figures 13 and 14). In this case, conventional distillation can be employed to separate 2PEA from the aralkyl alcohols mentioned above.…”

“…In this case, conventional distillation can be employed to separate 2PEA from the aralkyl alcohols mentioned above. 33 Streamwise component distribution is given in Table 4.…”

“…Hydrogenation of the entire mixture instead, followed by distillation, may therefore facilitate easy separation. 33 In our proposed aralkyl hydroperoxide-based reaction network (Figure 3) targeted to produce 2PEA, hydrogenation of STOX becomes an integral part of the scheme inevitably. Aralkyl alcohols such as 1PEA and CA are coproduced with STOX during the epoxidation reaction.…”

“…Hence, it is evident that STOX has to be separated from the reaction mixture by an energy- and cost-intensive distillation sequence. Hydrogenation of the entire mixture instead, followed by distillation, may therefore facilitate easy separation …”

Isobaric Vapor–Liquid Equilibrium Data for the Isopropanol–Water System

“…In addition, the test on the thermodynamic consistency based on the methodology proposed by Redlich and Kister 47 was performed for all the obtained experimental data. This test was chosen to verify the thermodynamic consistency of the experimental data because of its wide use in the literature, for instance in the works by Martin et al, 48 Vargas et al, 49 Parsana et al 50 and Das et al 51 The area test has been chosen also because it does not require (and the results do not depend on) any thermodynamic model, differently from a point-to-point test.…”
