Abstract:
      The effects of three phenolic antioxidants BHA，TBHQ，PG and three amine antioxidants TEPA，OPD, ADPA and their compound antioxidants on the induction period of rapeseed oil biodiesel were determined by Rancimat method, and the synergistic antioxidation mechanism was studied. The results showed that the induction period of rapeseed oil biodiesel was 2.03 h, which could not reach the national standard(6 h).The antioxidant effect of TBHQ was the strongest, followed by TEPA, PG, BHA, OPD and ADPA, when the antioxidant dosage was 0.4%. The antioxidant effect of compound antioxidants of phenolic antioxidant and TEPA increased the most obviously, followed by phenolic antioxidant compound with OPD. The compound effect of phenolic antioxidant and ADPA was the worst.
