- Abstract
In this study, biodiesel (OSRB) from degummed oilseed radish oil (OSR) was obtained by transesterification, and the effect on its thermal stability of a binary compound containing a conventional antioxidant and a solvent dye was evaluated. A combination of the traditional antioxidant tert-butylhydroquinone (TBHQ) and a solvent dye, so-called CI Solvent Blue 35 (SB-35), was prepared and incorporated into OSR and OSRB prior to analysis. The acid value, peroxide value, and induction period were measured, and it was found that TBHQ and SB-35 were highly effective in stabilising OSR and OSRB when used in combination. The TBHQ/SB-35 blend had strong antioxidation activity, even at very low concentrations, when compared with the addition of the individual compounds. In summary, the results showed that a TBHQ/SB-35 blend may be successfully used as an alternative additive for improving oil and biodiesel preservation.
