Abstract

In the transesterification process, the problem is the low solubility of oil in methanol, so the reaction will run slowly. The solution to this problem is to add a co-solvent to increase the solubility so that a one-phase reaction will be formed. The co-solvent methyl ester is the right choice because it is a product of the reaction itself so that it does not require a separation process. The operating conditions of the study were mass of palm oil 250 g, mass of NaOH catalyst 0.8%wt, stirring speed 100 rpm, reaction temperature 60oC, the molar ratio of oil:methanol = 1:6, reaction time (5,10,15,20,25,30 minutes), and the mass of co-solvent (0,5,10,15%wt). The first stage of the research was to make co-solvent, then proceed with the transesterification reaction by adding co-solvent which was carried out according to the research operating conditions. The optimum condition of the study was obtained at reaction time 30 minutes and the addition of co-solvent 5%, with yield 97.4171%. The density of FAME 0.88 g/mL and the concentration of FAME 99.963% which complied with SNI 7185-2015. The simulation results of ChemDraw for components of triglyceride+methanol+NaOH+co-solvent obtained kinetic energy 3479.0264 kJ/mol and dipole moment 43279.8007 debyes
