A novel phenolic-ester denoted as Bz–4–tBz was synthesized by esterification reaction between the1,2,4,5-benzenetetracarboxylic acid and 3,5-di-tert-butyl-4-hydroxybenyl alcohol in N,N0-dimethyla-cetamide using N,N0-dicyclohexylcarbodiimide as catalyst. The Bz–4–tBz was evaluated as antioxidantin polyol by the rotatory bomb oxidation test while the Rancimat test were also done for evaluating theantioxidant potential in the biodiesel (B100) and blended diesel (B20). The RBOT time of polyol wasobserved to be increased from 6.72 min to 17.42 min when blended 2000 mg/kg Bz–4–tBz in it. Theoxidation stability of biodiesel (B100) and blended diesel (B20) was also found to be increased.
