In this study the correlation of phase equilibrium data of ternary system (water + citric acid + 2-ethylhexanol) under atmospheric pressure at 298.15 K were investigated. Tie lines experimental data with the use of acidimetric titration method, the Karl Fischer technique and measuring the refractive indexes were determined. Distribution coefficients and selectivity factors were calculated for each tie line .Compatibility experimental data by Othmer-Tobias and Hand equations was evaluated and the results showed a good agreement. For the regression of experimental data, NRTL and UNIQUAC models were used to compare and the results showed good accordance with experimental results.
