Vapor–Liquid Equilibrium for the 2-Ethoxyethanol–2-Ethoxyethyl Acetate System

Abstract

Isobaric vapor−liquid equilibrium data for pure components as well as binary mixtures of 2-ethoxyethanol−2-ethoxyethyl acetate was generated using a modified ebulliometer. Measurements are reported for five different pressures in the range of (53 to 101) kPa. Pure component vapor pressures were correlated using the Antoine correlation and compared with the literature data. Binary mixture isobaric data was modeled using the Margules 2-suffix, Margules 3-suffix, van Laar, Wilson, nonrandom two-liquid (NRTL), and universal quasichemical (UNIQUAC) equations. Deviation plots for experimental and predicted temperatures are given.

Measurement and Correlation of Isobaric Vapor Liquid Equilibrium Data for Cyclopentyl Methyl Ether and Cyclopentanol

“…The chromatogram for an individual component showed a single peak ascertaining the absence of impurities. The pure component vapor pressure and binary VLE ( T – x ) data were generated at five different pressures ranging from 71.50 to 101.79 kPa using a differential ebulliometer setup (Figure ) used in the previous investigation . Since the operating pressures were subatmospheric, the vapor phase was assumed to be ideal.…”

“…The pure component vapor pressure and binary VLE (T−x) data were generated at five different pressures ranging from 71.50 to 101.79 kPa using a differential ebulliometer setup (Figure 1) used in the previous investigation. 6 Since the operating pressures were subatmospheric, the vapor phase was assumed to be ideal. The temperature was measured using a precalibrated mercury-inglass thermometer having a least count of 0.2 °C, and the pressure was measured with a mercury manometer with 0.1333 kPa (1 mmHg) accuracy.…”

“…The parameters of Wilson, UNIQUAC, and NRTL models 7 were determined by regression analysis. A two step process as discussed in previous work 6 was followed to regress the model parameters and estimate the vapor phase mole fraction. First, BUBL P calculations were performed to regress the parameters of the activity coefficient models under consideration by minimizing the RMSD based on the pressure.…”
