| Summary: | Biodiesel is an alternative diesel fuel to replace the fossil oil. Biodiesel is prepared through trans-esterification of vegetable oil or animal oil. Biodiesel produce low emission and environment friendly. Beside those advantages, biodiesel is freeze at relatively high temperature compared to fossil fuel. Cloud point depend on composition and molecular structure differences of the fatty acid ester. Branched fatty acid ester in biodiesel, can reduce cloud point value. In this research, we synthesized the branced fatty acid in biodiesel from palm oil, by epoxidation and subsequence esterification of unsaturated fatty acid components. 9,10 di-achetyl methylstearate is detected as a new component in the modified biodiesel. These modified biodiesel can be used as an effective blending component to reduce the cloud point of biodiesel. |
