Oxidative stability is a critical factor to ensure the quality of biodiesel. Here researched the inoxidizability of tertiary butyl hydroquinone(TBHQ)on biodiesel systematically and quantificationally with 873-type oxidative stability analyzer of biodiesel, according to European Standard(EN14214-2002). The result showed TBHQ obvious advantage over butylated hydroxyarisol(BHA) , which was another common antioxidanL So it can be used as an ideal antioxidant for biodiesel.%生物柴油的氧化安定性是确保生物柴油品质的关键因素.本文采用欧盟标准(EN14214-2002),使用瑞士万通公司生产的873型生物柴油氧化安定性测定仪,采用在植物油抗氧化方面最常用、最有效的特丁基对苯二酚(TBHQ)对由地沟油、大豆油和棉籽油制成的生物柴油的抗氧化性进行了系统的定量研究.结果表明,当添加量大于0.6‰时,3种生物柴油抗氧化时间均超过国标规定的6h.TBHQ是一种理想的生物柴油抗氧化剂,对比另一种常用的抗氧化剂BHA(叔丁基对羟基茴香醚)抗氧化性能优势明显.
