Abstract

DELGADO, Arnoldo E; PALACIO, Oscar  and  APERADOR, William. Effect of Butylated Hydroxytoluene (BHT) on the Oxidative Stability of a Lubricant Based on Sesame Oil. Inf. tecnol. [online]. 2015, vol.26, n.4, pp.81-88. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642015000400011.

In this study, the effects of butylated hydroxytoluene on degradation characteristics of sesame oil (Sesamum indicum) were investigated using different concentrations of antioxidant (0.05; 0.1; 0.2 and 0.5 %w/w). Oxidative stability of samples was determined by differential scanning calorimetry. Adding 0.1% antioxidant showed higher oxidation resistance of sesame oil. Various samples with concentration of 0.1% antioxidant were prepared in order to analyze the effect of BHT on other properties of the oil. A sample with the same amount of butylated hydroxytoluene showed less degradation of sesame oil in tribological testing (Preventive Wear) without altering the lubricity. Adding the same amount of antioxidant did not modify the viscosity index, but affected the melting and crystallization temperature of sesame oil.

Keywords : sesame oil; BHT; DSC; oxidative stability; tribology.
