Resumo: | 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. |

Con el descubrimiento del petróleo a principios del siglo XIX, se intensificó aún más el proceso de industrialización, provocando una intensa modificación del espacio ocupado por el hombre. Pero la escasez inminente, la generación de energía a través de combustibles fósiles como el petróleo, no puede suplir indefinidamente la energía requerida por la población mundial. En este contexto, el biodiésel surge como un prometedor biocombustible sustituto de los combustibles fósiles derivados de semillas oleaginosas o grasas animales compuestas por ésteres alquílicos que pueden sustituir total o parcialmente al diésel. Sin embargo, contiene una cantidad significativa de ácidos grasos insaturados y es susceptible a la degradación oxidativa mediada por calor, especialmente en presencia de oxígeno, lo que puede afectar negativamente la estabilidad del biodiesel. compuestos fenólicos sometidos a la reacción electroquímica del biodiesel obtenido a partir del aceite de soya, mediante la reacción electrolítica se buscaron cambios estructurales para mejorar la actividad antioxidante técnica del LCN, utilizando metanol e hidroquinona como solvente y como electrolito. El LCCHQ fue el producto de esta reacción cuya eficiencia antioxidante como aditivo para biodiesel fue medida por el "Schaal Oven Storage Stability Test" - método de oxidación acelerada y posteriormente analizado por espectroscopía de absorción molecular en la región UV (240 a 300 nm) y rancimat. Los resultados de la actividad antioxidante de LCCHQ fueron satisfactorios para retardar el progreso de la oxidación en comparación con CNSL en todas las pruebas técnicas.A energia é considerada questão estratégica de um páis e a proporção de seu uso sempre esteve diretamente associada ao desenvolvimento industrial.
