Biodiesel was synthesized with castor oil and methanol in the presence of CH3 ONa as catalyst. The optimal conditions were found to be as follows:reaction time was 2 h, reaction temperature was 60 ℃, the mole ratio of mthanol to oil was 7∶1, the dosage of catalyst was 1. 1%. The yield of biodiesel reached 90% under the optimized conditions, the preparation was featured by high catalytic activity, simple process and less cost.
