Abstract

Refined, bleached and deodorized (RBD) palm oil is one of the interesting renewable resources in biolubricant application. It is due to some advantages such as biodegradable, non-toxic, excellent lubricity and high viscosity index properties. However, direct application of RBD palm oil as biolubricant is restricted due to its poor low temperature property, which limits its use at low operating temperature. This drawback can be overcome by molecule structural redesign through chemical modification process. To produce palm oil based biolubricant with good pour point, epoxidized palm oil (EPO) was chemically modified via ring opening process. EPO was reacted with oleic acid in the presence of p-toluenesulfonic acid (PTSA) as catalyst. The molecular structure confirmation of ring opening product which is palm oil hydroxy oleate (POHO) was proven through the oxirane oxygen content (OOC) value, iodin value, hydroxyl value, Fourier transformation infra-red (FTIR), proton and carbon nuclear magnetic resonance (1H-NMR and 13C-NMR) spectroscopy analysis. The physicochemical properties of POHO were determined through its pour point and flash point values. The results showed that the ring opening process for putting bending and branching molecule structures of the oil have improved the pour point (-8.5 °C) and increased the flash point of the biolubricant (255 °C).
