常规抗氧化剂在生物柴油中的抗氧化和油溶性能研究
|
摘要
根据《中国药典》(2015版)中规定的方法和Rancimat法研究常规抗氧化剂在地沟油生物柴油中的抗氧化性能和油溶性能及其关联性能。结果表明:10种常规抗氧化剂均能在一定程度上提高地沟油生物柴油的抗氧化性能,只是抗氧化效果差别较大。在常温20℃时,常规抗氧化剂的油溶性能相对较差,差别也较大,10种常规抗氧化剂在地沟油生物柴油中的油溶性能由大到小的顺序为:丁基羟基茴香醚(BHA)>特丁基对苯二酚(TBHQ)>植酸(PA)>二特丁基对苯二酚(D-TBHQ)>没食子酸丙酯(PG)>没食子酸辛酯(OG)>抗坏血酸(V_C)>没食子酸甲酯(MT)>L-抗坏血酸棕榈酸酯(AP)>没食子酸(GA)。10种常规抗氧化剂的油溶性能均随温度的升高而得到改善,但溶解特性变化不大,在一定程度上10种常规抗氧化剂的抗氧化性能的良莠与油溶性能两者之间关联性不强。
According to the method of"Chinese pharmacopoeia"(2015 edition) and Rancimat,we study the conventional antioxidants oxidation resistance and oil soluble and their associated performance in biodiesel. The results indicated that ten kinds of conventional antioxidants can improve the oxidation resistance of biodiesel to some extent,but the antioxidant effect are different. At the normal temperature of 20 ℃,the oil solubility of conventional antioxidants are relatively poor,and the distinction are large. The order of oil solubility of ten kinds of conventional antioxidants is as fellows: BHA>TBHQ>PA>D-TBHQ>PG>OG>V_C>MT>AP>GA. The oil solubility of ten kinds of conventional antioxidants is improved with the increase of temperature,but no obvious change in solubility. To a certain extent,There is no strong correlation between the antioxidant properties of 10 conventional antioxidants and their oil soluble properties.
