ISO 12966-2:20 11规定了制备脂肪酸甲酯的方法。它包括由动植物油脂、脂肪酸和皂类制备脂肪酸甲酯的方法。为了满足不同的要求，规定了四种甲基化方法，即:a)碱性条件下的“快速”转甲基化方法；b)在连续的碱性和酸性条件下的“一般”转甲基化/甲基化程序；c)BF3转甲基化程序；d)使用酸催化的甘油酯甲基化的替代方法。如此制备的甲酯用于需要此类衍生物的各种分析方法，例如气液色谱(GC)、薄层色谱(TLC)和红外光谱(IR)。
ISO 12966-2:2011 specifies methods of preparing the methyl esters of fatty acids.It includes methods for preparing fatty acid methyl esters from animal and vegetable fats and oils, fatty acids and soaps. To cover different requirements four methylation methods are specified, namely: a) a "rapid" transmethylation procedure under alkaline conditions; b) a "general" transmethylation/methylation procedure under sequential alkaline and acid conditions; c) a BF3 transmethylation procedure; d) an alternative procedure using acid-catalysed transmethylation of glycerides.Methyl esters so produced are used in various analytical procedures requiring such derivatives, e.g. gas-liquid chromatography (GC), thin-layer chromatography (TLC), and infrared spectrometry (IR).
