Energy is considered a strategic issue for a country and the proportion of its use has always been directly associated with industrial development. With the discovery of oil at the beginning of the 19th century, the industrialization process was intensified even more, causing an intense modification of the space occupied by man. But the impending shortage, the generation of energy through fossil fuels such as oil, cannot indefinitely supply the energy required by the world's population. In this context, biodiesel emerges as a promising biofuel substitute for fossil fuels derived from oilseeds or animal fats composed of alkyl esters that can totally or partially replace diesel. However, it contains a significant amount of unsaturated fatty acid and is susceptible to heat-mediated oxidative degradation, especially in the presence of oxygen, which can negatively affect the stability of biodiesel. phenolic compounds submitted to the electrochemical reaction of biodiesel obtained from soybean oil, through the electrolytic reaction, structural changes were sought to improve the technical antioxidant activity of LCN, using methanol and hydroquinone as solvent and as electrolyte. The LCCHQ was the product of this reaction whose antioxidant efficiency as an additive for biodiesel was measured by the "Schaal Oven Storage Stability Test" - accelerated oxidation method and later analyzed by molecular absorption spectroscopy in the UV region (240 to 300 nm) and rancimat. The antioxidant activity results of LCCHQ were satisfactory in retarding the progress of oxidation when compared to CNSL in all technical tests.
