ABSTRACT

Isobaric vapor-liquid equilibrium (VLE) data were determined for the binary systems 3-methylbutan-1-ol (3-methyl-1-butanol) + ethyl (2S)-2-hydroxypropanoate (ethyl lactate) and pentan-1-ol (1-pentanol) + ethyl lactate at two pressures (13.0 and 101.3 kPa). The data were obtained using a vapor recirculating-type equilibrium device. Calculations of the nonideality of the vapor phase were made with the second virial coefficients evaluated from the Hayden-O Connell method. VLE experimental data were tested by Herrington and a modified DECHEMA test, which proved their thermodynamic consistency. The activity coefficients and boiling points of the solutions were well correlated with the mole fraction using Wilson, NRTL, and UNIQUAC equations. The mixtures do not present azeotropes.
