Interpretive Summary:

Technical Abstract: A novel antioxidant, epoxidized cardanol (ECD), derived from cardanol has been synthesized and characterized by FT-IR, 1H-NMR and 13C-NMR. Oxidative stability of ECD in vegetable oils and biodiesel was evaluated by the pressurized differential scanning calorimetry and Rancimat methods, respectively. The results indicated that ECD exhibited antioxidative activity in soybean oil and increased its onset temperature by nearly 10°C with 0.7 wt.% ECD. It was also observed that other vegetable oils showed significantly improved oxidative stability with the addition of 0.7 wt.% ECD. Olive oil showed the highest increased onset temperature by 19.5°C. Furthermore, the ECD has superior antioxidant activity compared to the synthetic antioxidant butylated hydroxytoluene and, thus, could be used as an optimized primary antioxidant for biodiesel. ECD could be a new bio-based antioxidant with better thermal stability.
