CNSL - Used as an antioxidant in biodiesel

CNSL can be used as an antioxidant in biodiesel
CNSL liquid can be used as an antioxidant in biodiesel. Small concentrations as 0.1% m/m or less are enough to increase the IP, thereby extending the stability of the biofuel. The inverse correlation between the IP values and the calculated values of the rate constant of the reaction, k, through equation 3, clearly indicates that the added CNSL reacts with the free radicals formed in the oxidation process, leading, as a consequence, to the increase of the oxidation stability. With respect to the parameters of activation determined in this work, they allowed to suppose that a dissociative mechanism contributes for the oxidation reaction.
