Abstract

Ternary and quaternary liquid-liquid equilibria of three solutions (water + trimethylolpropane (TMP) + 2-ethylhexanol, water + TMP + octan-1-ol, and water + TMP + 2-ethylhexanol + formaldehyde) were studied at 298.15 K under atmospheric pressure. The consistency of the measured tie-line data was evaluated using the Othmer-Tobias, Bachman, and Hand equations. The properties of solvents, such as distribution constants, separation factors, and insolubilities, were examined in the ternary and quaternary liquid-liquid equilibrium systems. NRTL and UNIQUAC models were used to regress the ternary and quaternary systems and calculate binary interaction parameters. Finally, a comparison of experimental and calculated data, using the NRTL and UNIQUAC models, was performed.
