“…They work synergistically and modify fuels' properties by increasing their degradation and, consequently, corrosivity 2 . The continuous increase in corrosivity is mainly caused by the formation of many acids: formic, acetic, propionic and caproic acids, among other 3 . Another relevant subject consists of the fact that biodiesel is thirty times more hygroscopic than mineral diesel and it means that biodiesel has greater natural tendency to absorb humidity.…”

“…Thus, biodiesel degradation speeds up 4,6,7 . Due to biodiesel low hydrolytic and oxidative stability, its storage is a critical factor because it may change the quality of the product and promote a corrosion that would be practically null with the use of petroleum diesel [1][2][3]5 . Such negative results lead to vulnerability and generate problems that may compromise the use of biodiesel as a viable alternative for the existing fuel matrix found in the market.…”

“…The oxidative degradation of biodiesel occurs primarily as a result of contact with metal, light, air and/or heat during its storage and distribution. Metal and light are pro-oxidants that affect the oxidation rate (Aquino et al, 2012), but contact with air and elevated temperature are the most deleterious parameters related to biodiesel degradation (Godoy et al, 2013). It is recognized that, in general, the rate of a chemical reaction approximately doubles for every 10 °C increase (Stoker, 2010).…”

SUMMARY:This paper proposes to examine the effect of temperature on the oxidation behavior of biodiesel. Soybean biodiesel was oxidized at different temperatures (room temperature, 60, and 110 °C), and the increase in primary and secondary oxidation products was determined based on the peroxide and anisidine values, respectively, during the induction period (IP). The results indicated that the evolution of hydroperoxides followed zero-order reaction kinetics during the IP at all temperatures, and their rate of formation was exponentially affected by temperature. It was also deduced that temperature influenced the ratio between primary and secondary oxidation products formation, which decreased as the temperature increased. Additionally, it was possible to predict the oxidation behavior of the soybean biodiesel at room temperature by an exponential model fitted to the IP values at different temperatures (70, 80, 90, 100, and 110 °C) using the Rancimat apparatus.KEYWORDS: Oxidation kinetic; Oxidation products; Soybean biodiesel; Temperature; Tocopherols RESUMEN: Influencia de la temperatura en la oxidación de biodiesel de soja. El propósito de este trabajo es evaluar el efecto de la temperatura en el comportamiento oxidativo del biodiesel. Biodiesel derivado de aceite de soja fue oxidado a diferentes temperaturas (temperatura ambiente, 60 y 110 °C) y se evaluaron el contenido de compuestos primarios y secundarios de oxidación mediante el índice de peróxidos y de anisidina, respectivamente, a lo largo del periodo de inducción. Los resultados indicaron que el contenido de hidroperóxidos evolucionó siguiendo una cinética de orden cero a lo largo del periodo de inducción a todas las temperaturas y que su velocidad de formación cambió exponencialmente con la temperatura. También se dedujo que la temperatura influyó en la relación entre la formación de los productos de oxidación primarios y secundarios, disminuyendo a medida que aumentaba la temperatura. Además, fue posible predecir el comportamiento oxidativo del biodiesel de soja a temperatura ambiente ajustando a un modelo exponencial los valores de periodo de inducción obtenidos a diferentes temperaturas (70, 80, 90, 100 y 110 °C) mediante un equipo Rancimat.
