Özet

Liquid-liquid equilibrium (LLE) data of the solubility (binodal) curves and tie-line compositions were examined for mixtures of (limonene (1) + linalool (2) + ethylene glycol or diethylene glycol or triethylene glycol or 1,2-propylene glycol (3)) at 298.15 K and 101.3 +/- 0.7 kPa. The relative mutual solubility of linalool is higher in the limonene layers than in the ethylene glycol or diethylene glycol or triethylene glycol or 1,2-propylene glycol layers. The reliability of the experimental tie-line data was confirmed by using the Othmer-Tobias correlation. The LLE data of the ternary systems was predicted by the UNIFAC method. Distribution coefficients and separation factors were evaluated for the immiscibility region.
