Abstract

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.
