Abstract: Biodiesel is an alternative diesel fuel defined as the mono-alkyl esters of vegetable oils or animal fats which can fulfill energy security needs without sacrificing engine’s operational performance. In this paper the relationship between the chemical structure and physical properties of biodiesel esters is analyzed and compared with conventional diesel fuel. The biodiesel were made using different oils and sodium hydroxide as catalyst in laboratory scale. The physico-chemical properties assessed includes, density, flash point, kinematic viscosity and calorific value.

Keywords: fuel, biodiesel, density, viscosity, methyl esters
