Liquid–liquid equilibrium data were determined for the two ternary systems of water + thioglycolic acid (TGA) + 2-ethyl-1-hexyl thioglycolate (ETE) and water + 2-ethyl-1-hexyl thioglycolate (ETE) + 2-ethyl-1-hexanol (EHL) at 293.15, 303.15, and 313.15 K under 101 kPa. The nonrandom two-liquid (NRTL) and universal quasi-chemical (UNIQUAC) activity coefficient models were used to correlate the experimental LLE data. The LLE data calculated by the NRTL and UNIQUAC models were in good agreement with the experimental ones.
Densities of binary mixtures of 1,3-diethyl propanedioate with methanol, ethanol, propan-1-ol, propan-2-ol, butan-2-ol, 2-methyl-propan-1-ol, and pentan-1-ol have been measured at temperatures of (288.15, 298.15, 313.15, and 328.15) K using an Anton Paar model DMA 5000 M oscillating densimeter. Excess molar volumes were calculated from these densities. The experimental data were fitted to the Redlich−Kister equation.
