ABSTRACT
This work reports liquid-liquid equilibrium (LLE) data for the mixtures {water (1) + morpholine (2) + ethyl nonanoate, dimethyl phthalate, or isoamyl alcohol (3)} at 298.15 K and 101.3 kPa. The solubility curves and tie-line end compositions were examined for the related mixtures. The reliability of the experimental tie-line data was verified by using the Othmer-Tobias correlation. Distribution coefficients and separation factors were evaluated for the immiscibility region. Although all of the proposed solvents show low distribution coefficients, they can be served as convenient agents for extracting morpholine from aqueous medium, since they exhibit high separation factors. The experimental tie-line data were correlated by universal quasichemical activity coefficient (UNIQUAC) model representing the LLE data for these systems with respect to tie-line slopes only.
