This study aims to evaluate the oxidation stability and tribological characteristics of palm oil-based Trimethylolpropane (TMP) synthetic ester (Palm Methyl Ester (PME)) as a bio-lubricant. The synthesis process was carried out through two-stage transesterification using Trimethylolpropane (TMP) as reactant and sodium methoxide as catalyst, with variations in reaction time to determine the optimum operating conditions. The results showed that increasing the reaction time tended to increase the conversion rate up to the optimum point, before the conversion rate decreased near equilibrium. The PTMPE product shows high oxidation stability with an oxidation time of 295.20 minutes, superior to mineral oil (MO), palm oil (PO), and soybean oil (SBO) based lubricants. In addition, PTMPE has a kinematic viscosity that matches the ISO VG 10 category, making it ideal for lubricant applications in high-speed and low-temperature engines. This study used a four-ball tribotester to evaluate COF under standard conditions. Results show that the strong intermolecular structure of PTMPE provides viscosity stability during friction, despite changes in temperature and pressure. Thus, PME-basedtrimethylolpropane TMP synthetic ester has promising potential as an environmentally friendly alternative in the lubricant industry.
Keywords: Bio-lubricant, Synthetic Trimethylolpropane (TMP) Ester, Oxidation Stability, Viscosity, Tribology, Palm Oil.
