LIQUID - LIQUID EQUILIBRIA IN HYDROCARBON PLUS 3-METHOXYPROPIONITRILESYSTEMS, CORRELATION AND PREDICTION

Liquid-liquid equilibria (LLE) for ternary system n-hexadecane + butyl benzene + 3-methoxypropionitrile (3MOPN) at 298.15 K are reported. The se experimental results and earlier published ones dealing with mixtur es of other hydrocarbons and 3MOPN were correlated using the NRTL and the UNIQUAC equations. The UNIFAC-LLE parameters for the some hydrocar bons groups with 3MOPN were calculated from experimental binary and te rnary LLE. The prediction of liquid-liquid equilibria for ternary hydr ocarbons + 3MOPN systems were compared with the experimental data.
