Abstract: The objective of the present work was to evaluate the effect of the addition of dichloromethane extract obtained from Ginger rhizomes (Zingiber officinale Roscoe) in biodiesel, as well as to compare the results obtained with the synthetic antioxidants BHT and TBHQ. The soybean methyl biodiesel (BMS) used was produced in our laboratory. The thermal behavior of the extract, synthetic antioxidants and biodiesel produced were evaluated using TG/DTG techniques. The additions of EDG and BHT and TBHQ were performed in increasing proportions relative to the mass of the extract: mass of the methyl biodiesel and the samples were stored under the same conditions and studied for storage time of up to ninety days using TG/DTG and method to evaluate the action of the addition of these antioxidants in inhibiting and/or retarding the oxidative stability of the biodiesel samples. After 90 days of storage, the BAN-4 sample had the highest initial decomposition temperature. Regarding the oxidative stability, the samples with EDG additions also presented values higher than the minimum regulated by the ANP, confirming the action of the antioxidants present in the EDG in the control of the oxidation reactions of BMS.
