This study aimed at producing biodiesel from Jatropha oil using ZSM-5 as heterogeneous catalyst at different temperature of 70, 80, 90, 100 and 1100C was accomplished. The transesterification was carried out maintaining a butanol to oil ratio of 6:1, a reaction time of 2 hours, a catalyst loading of 0.5 g ZSM-5 and a settling time of 24 hours. An optimum yield of 56 % was obtained at 110 ˚C; the highest temperature under consideration. This gives a biodiesel which meet the EN 14214 and ASTM D 6751 standards with the following properties; Acid value of 0.486 mg KOH/g, density of 0.8485 g/ml, cloud point of 14 ˚C and a flash point of 145 ˚C. The average yield may be attributed to the reaction parameters that were kept constant.
