| 中文摘要: |
| 采用Rancimat法研究3种酚类抗氧化剂丁羟基茴香醚（BHA）、叔丁基对苯二酚（TBHQ）、没食子酸丙酯（PG）与3种胺类抗氧化剂四乙烯五胺（TEPA）、邻苯二胺（OPD）、二烷基二苯胺（ADPA）及其复配对菜籽油生物柴油诱导期的影响，并对其复配后协同抗氧化机理进行了分析。结果表明：菜籽油生物柴油的诱导期为2.03 h，达不到国家标准（6 h）；6种抗氧化剂在添加量为0.4％时，抗氧化效果强弱顺序为TBHQ>TEPA>PG>BHA>OPD>ADPA；酚类抗氧化剂与TEPA复配的抗氧化效果增加最明显，其次是酚类抗氧化剂与OPD复配，而ADPA与酚类抗氧化剂复配效果最差。 |
| 英文摘要: |
| 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. |
