Abstract

Biolubricant production of trimethylolpropane ester (ET) was conducted via esterification of fatty acid (FA) of Jatropha curcas oil with trimethylolpropane (TMP). The condition for this reaction was as follows: temperature was 150 °C, time of reaction was 3 hours, molar ratio of FA: TMP was 4:1 and 2% wt/wt concentrated catalyst (based on weight of FA). Different catalyst was used in this reaction such as perchloric acid, sulfuric acid, p-toluenesulfonic acid, hydrochloric acid, and nitric acid. The composition of ET was determined by Gas Chromatography (GC-FID). The ester group was confirmed by Fourier Transform Infrared Spectroscopy (FTIR) and the structure was confirmed by proton and carbon Nuclear Magnetic Resonance ( 1H-NMR and 13C-NMR) spectra. 70% of ET was successfully synthesized using perchloric acid in this research. The pour point of the product was observed as low as -23 °C, flash point is >300 °C and viscosity index is 150.
