This research is aimed to study the synthesis of mercapto ethyl ester of fatty acid (MEFA) using palm fatty acid distillate (PFAD). The synthesis was carried out in a jacketed stirred vessel. Water as a byproduct was removed by using vacuum evaporation. p-Toluene sulfonic acid was used as catalyst. Temperature, mercaptoethanol excess, and catalyst amount were varied during the experiments. The variations ranges were 60-80°C, 5-25 %-mole, and 0.8-3.2 %-mole, respectively. The accomplishment of reaction was evaluated by measuring the mercaptan content and yield of MEFA. The mercaptan content and yield of MEFA were in the ranges of 6.4-8.0% and 64-86%, respectively. It was found that mercaptan content and yield increased with temperature. The optimum temperature was found to be 70°C, considering the mercaptan content, yield, and appearance of the product obtained. A full 22 factorial design at a reaction temperature of 70°C showed that mercaptoethanol excess and catalyst amount had significant effects on the mercaptan content and yield of MEFA.
