Abstract

The production of polyesters based on oleic acid and trimethylolpropane (TMP) or pentaerythritol (PE) as potential biolubricant were carried out. The esterification processes between oleic acid with TMP or PE were carried out using sulfuric acid as a catalyst. The esterification process produced high yield between 92%-94% w/w respectively. The formation of polyesters was confirmed using gas chromatography (GC-FID), Fourier Transform Infrared Spectroscopy (FTIR) and Nuclear Magnetic Resonance (NMR). The polyesters were analyzed for basic lubrication physicochemical properties. The results showed that polyesters of both TMP and PE having high viscosity index between 200-309, good pour points ranging from -42°C to -59°C and high flash points of 280°C - 300 °C respectively. The polyesters also showed good thermal oxidative stability with TGA onset temperatures above 180 °C. In general both products are plausible to be used as biolubricant for industrial application.
