| Summary: | The synthesis of biodiesel using rubber seed oil by a transesterification reaction using cement clinker catalysts was studied. The mineral composition and morphology of both the catalysts were analysed using X-ray diffraction and scanning electron microscopy. The gas chromatography–mass spectrometry, Fourier transform infrared spectroscopy and nuclear magnetic resonance studies were used to find the Fatty acid methyl ester content and various compounds of esters in the synthesised biodiesel, which showed an efficient conversion of rubber seed oil to biodiesel. The highest yield of 80% was obtained from calcium oxide catalyst (1.5 g) activated at 50°C with a methanol-to-oil ratio of 6:1. The highest yield of 70% biodiesel was obtained using a cement clinker catalyst (0.5 g) activated at 50°C with a methanol-to-oil ratio of 6:1. The significant physical properties of biodiesel flash point, acid value and saponification value were found, and the results are within the American standard test method (ASTM D6751) limits. |
