In this study, soaps, cosmetics, lubricant oil, and raw material for biodiesel, a mixture of fatty acid and natural conditions in the extraction and purification process to be used for basic data that solid - liquid equilibria of fatty acids data by measuring the equilibrium applying the solid - liquid equilibrium model prediction phase equilibria model. The solubilities data measured was cooling curve method. cooling curve method measured of freezing point and Experimental equipment. Using the measured data to determine the activity coefficient model equilibria data Van Laar, Wilson, NRTL, UNIQUAC model is applied to the coefficients of each of the equilibrium model were determined. |
