Abstract

Liquid-liquid equilibrium data are presented for mixtures of (water (1) + propionic acid, or propanol (2) + 1,8- cineole (3)) at T = 291.15 K and P = 1 atm. The ternary systems exhibit type-1 behavior of LLE. The tie-line data were correlated using the NRTL model. Moreover, the binary interaction parameters of this model were obtained by minimizing well defined objective functions using the Genetic Algorithm (GA) and the Particle Swarm Optimization (PSO). In addition, the reliability of the experimental tie-line data was determined through the Othmer–Tobias and Hand plots. Finally, Distribution coefficients (D) and separation factors (S) were calculated to evaluate the capability of solvent for separation of acid or alcohol from water.
