The oxidative stability of castor oil based biodiesel, added different antioxidant, was studied systematacially through pressure differential scanning calorimetry (PDSC), accelerated oxidation test, constant temperature method, programmed temperature method. The result shows after adding antioxidant in castor oil, the generation of hyperoxide and acid value were suffocated for the biodiesel. When the content of antioxidant 300 was 0.6 wt.%, the initiation oxide temperature raised to 197.7°C, the acid value reduced to 1.41, the solubility of oxide reduced to 1.40mg/100mL, and the activity energy of oxidation was 48.18kJ/mol.
