Abstract

This study aimed to evaluate the sucrose acetate isobutyrate (SAIB) as an antioxidant in ethyl biodiesel sample obtained from crude soybean vegetable oil at 0, 1000, 2000, 3000, 4000 and 5000 ppm concentrations, by thermal analysis, to know if the SAIB could be suitable as an antioxidant in biodiesel. Initially, the physicochemical properties of both soybean vegetable oil and the biodiesel were evaluated by 1H NMR which showed that the samples were within normal limits recommended by ANVISA and ANP, respectively. The SAIB has been tested by TG/DTG/DTA, where the results demonstrated that the antioxidant presented significant thermal resistance and the best dosage of SAIB to protect the biodiesel sample tested was 5000 ppm. Although the results has been satisfactory, researches of oxidative resistance must to be carried out to improve the knowledge about the SAIB behavior as antioxidant in the biodiesel.
