Abstract
The chemical properties of biodiesel fuel are much depends upon the fatty ester composition. The Calophyllum inophyllum seed oil without purification in crude stage and purified Calophyllum inophyllum oil in degummed stage were studied. The Crude Calophyllum Inophyllum Oil (CCIO) and Degummed Calophyllum Inophyllum Oil (DCIO) was the test samples considered for fatty acid quantitative analysis. The composition of fatty acids was identified by using Gas Chromatography (GC) to quantitative the test samples. In the results, the higher percentage presence of straight chain saturated fatty acid (palmitic) and unsaturated fatty acid (linoleic and oleic) has identified in the CCIO sample. By Degumming process, the percentage level of saturated fatty acid Palmitic diminished and unsaturated fatty acid Linoleic increased respectively; also the lesser amount formation of saturated fatty acid Capric, but unsaturated fatty acid Oleic and saturated fatty acid Myristic was completely removed.
