Liquid-liquid equilibrium study for ternary systems of water + propargyl alcohol + solvents at 308.2 K: Measurement and thermodynamic modelling

•The LLE data for water + propargyl alcohol + solvents were obtained at 308.2 K.•The reliability of LLE data were verified by the O-T and Hand equations.•Experimental data were successfully correlated using the NRTL and UNIQUAC model.•The binary interaction parameter values were obtained from the data correlation.
