研究了常见7种生物柴油的氧化稳定性,分析了10种抗氧化剂对小桐子生物柴油氧化稳定性的影响。结果表明:只有棕榈油生物柴油的氧化稳定性能达到生物柴油国家标准;天然抗氧化剂VC、VE的抗氧化效果较差,且其添加量对小桐子生物柴油氧化稳定性影响也较小;GAM (没食子酸)抗氧化效果好,但油溶性能较差;TBHQ在添加量较高时对小桐子生物柴油氧化稳定性影响较大,AP( L-抗坏血酸棕榈酸酯)和TBHQ对精制和粗制小桐子生物柴油的抗氧化效果差别较大;MT(没食子酸甲酯)、PG(没食子酸丙酯)、OG(没食子酸辛酯)、BHA和BHT 5种抗氧化剂的抗氧化效果较好,且在添加量较低时对小桐子生物柴油氧化稳定性的影响较大,是较为理想的抗氧化剂。

The oxidation stabilities of seven common biodiesels were studied, and the effects of ten antiox-idants on oxidation stability of Jatropha curcas L. biodiesel were analyzed. The results showed that only the oxidation stability of palm oil biodiesel reached the national standard of biodiesel. The antioxidative effects of VC and VE were poor and their addition amounts had little effect on the oxidation stability of Jat-ropha curcas L. biodiesel;the antioxidative effect of gallic acid ( GAM) was good, but its oil solubility was weak;high dosage TBHQ had great effect on the oxidation stability of Jatropha curcas L. biodiesel, and the antioxidative effects of L-ascorbyl dipalmitare(AP)and TBHQ on crude and refined Jatropha curcas L. biodiesel were quite different;the antioxidative effects of low dosage methyl gallate( MT) ,pro-pyl gallate(PG),octyl gallate(OG),BHA and BHT on Jatropha curcas L. biodiesel were great, which were ideal antioxidants.
