Abstract The ternary systems of {(1-butanol or 1-pentanol) + (−)-trans-Cyclohexane-1,2-diamine + water} at (298.2–318.2) K under 100.02 kPa in terms of liquid-liquid equilibrium were investigated. The solubility data of each system were obtained by using cloud point method. For evaluation of extraction ability of the solvents used in this work, the distribution coefficients and separation factors were calculated and 1-pentanol was demonstrated to be very suitable. Besides, Othmer-Tobias and Hand correlation equations were applied to check the consistency of the tie-line data. Furthermore, NRTL and UNIQUAC models were used to correlate the experimental data with all the RMSD values less than 2.57%.
