摘要
研究了生物柴油中硬脂酸甲酯、油酸甲酯、亚油酸甲酯的气相色谱分析方法 ,确立了最佳分析条件。实验以水杨酸甲酯为内标 ,采用HP 1大口径毛细管色谱柱 ,不分流进样 ,使生物柴油中多种脂肪酸甲酯得到良好分离 ,建立了一种简单、快速、准确的生物柴油测定方法。硬脂酸甲酯、油酸甲酯、亚油酸甲酯的平均回收率为 95 0 0 %～ 99 2 7% (n =5 ) ,相对标准偏差为 0 6 4%～ 3 0 5 %(n =5 )。
A gas chromatographic method for the determination of fatty acid methyl esters in biodiesel was described.Methyl salicylate was used as the internal standard.Gas-chromatographic analysis was made by using HP-1 wide-bore capillary column and FID detector.Temperature programming run from 190℃ to 280℃.All components and internal standard were separated in 12 min.The results show that the method is simple,rapid and accurate.The recoveries are determined to be from 95 00% to 99 27%(n=5),the relative standard deviations from 0 64% to 3 05%(n=5).
