Abstract  

Oxidative stability is very important in the quality control of oils and biodiesel. Chemical characteristics, as acid, iodine and peroxide values, show the differences among samples and can be used by industries to evaluate the oxidation degree. In relation to advanced techniques, the use of PDSC to measure the oxidative induction time is very important. These measurements were used to evaluate the properties of castor oil after refining process and consequently the biodiesel characteristics. Oxidative induction time indicated that biodiesel samples were more stable than the refined oils. The biodiesel obtained from neutralized oil had a higher stability being probably related to the acid value.
