Abstract

The research of esterification kinetics of free fatty acid from liquid waste of coconut oil industry and methanol by using the montmorillonite carbon sulfonated had been carried out. Esterification was determined by variying the mole ratio between methanol and free fatty acid (10:1, 13:1, 16:1, 19:1 and 22:1), and the temperature reaction (60oC, 70oC and 80oC). Several kinetic parameters that was studied including Arrhenius constant, activation energy, reaction rate constant, and equilibrum constant. The results of the research showed that the Arrhenius constant was determined as 3.3085 x 106, therefore the activation energy for the forward reaction was determined as 0.0503 kJ/ mole. The initial rate constant was increasing as the higher temperature occured from 60oC to 80oC and decreasing as the mole ratio used from the lowest mole to the highest mole. The highest reaction rate constant occured when the temperature reaction was 80oC while the value of k1 was determined as 0.1187 and k2 was determined as 0.0595. The highest value of equilibrum constants (K) was 1,9955 at 80oC. Regression value of validation used in the study was 0.9803 and the slope was 0.9835 so that, this kinetics equation models are acceptable to calculate the kinetics of the esterification of free fatty acids.
