Abstract

Isobaric vapor-liquid equilibrium data of the binary systems comprising 2-ethoxyethanol, 2-ethoxyethyl acetate, and toluene were measured using an ebulliometer. The boiling temperatures of the binary mixtures are reported for six different pressures ranging from 53.3 to 101.3 kPa. The binary system 2-ethoxyethanol-toluene shows a low-boiling azeotrope around 90 mol % toluene. A nonrandom two-liquid (NRTL) model was used to fit the binary (PTx) data. The experimental data were verified using the thermodynamic consistency tests of Redlich-Kister and Wisniak. The reported data were compared with available literature data and modeling results. The studied systems are relevant for the design of azeotropic/reactive distillation columns for the esterification of 2-ethoxyethanol and acetic acid using toluene as an entrainer.
