E. Batista et al., Prediction of liquid-liquid equilibrium for systems of vegetable oils, fatty acids, and ethanol, J CHEM EN D, 44(6), 1999, pp. 1365-1369
Group interaction para:meters for the UNIFAC and ASOG models were specially
adjusted for predicting liquid-liquid equilibrium (LLE) for systems of veg
etable oils, fatty acids, and ethanol at temperatures ranging from 20 to 45
degrees C. Experimental liquid-liquid equilibrium data for systems of trio
lein, oleic acid, and ethanol and of triolein, stearic acid, and ethanol we
re measured and utilized in the adjustment. The average percent deviation b
etween experimental and calculated compositions was 0.79% and 0.52% for the
UNIFAC and ASOG models, respectively. The prediction of liquid-liquid equi
librium for systems of vegetable oils, fatty acids, and ethanol was quite s
uccessful, with an average deviation of 1.31% and 1.32% for the UNIFAC and
ASOG models, respectively.
