Figure 9. Antioxidant activity of “bio oil” (extract B) and a reference commercial antioxidant (BHT
6-ditertbutyl-4-methylphenol)-) against oxidation of DBS (2,6-di-tertbuthylo-4-methylophenol).
Concentration of DBS oxidation products versus time of oxidation in liquid phase at 150°C in the
presence of various antioxidants (“bio oil” and BHT) under investigation.
