BS EN ISO 12966-2:2017规定了脂肪酸甲酯的制备方法。它包括从动植物脂肪和油制备脂肪酸甲酯的方法 酸和肥皂。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”转甲基程序；b） 在连续的碱性和酸性条件下的“通用”转甲基化/甲基化程序；c） BF3转甲基程序；d） 使用酸催化甘油酯转甲基的替代程序。如此生产的甲酯用于各种需要此类衍生物的分析程序，例如:。 气液色谱法（GLC）、薄层色谱法（TLC）和红外光谱法（IR）。牛奶和奶制品（或来自牛奶和奶制品的脂肪）不在本协议范围内 文件交叉引用:ISO 661:2003 Ed 3ISO 1042:1998ISO 835:2007ISO 8655-2:2002 Ed 2ISO 4800:1998ISO 4799ISO 3696:1987ISO 78-2:1999购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS EN ISO 12966-2:2017 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 (GLC), thin-layer chromatography (TLC) and infrared spectrometry (IR).Milk and milk products (or fat coming from milk and milk products) are excluded from the scope of this document.Cross References:ISO 661:2003 Ed 3ISO 1042:1998ISO 835:2007ISO 8655-2:2002 Ed 2ISO 4800:1998ISO 4799ISO 3696:1987ISO 78-2:1999All current amendments available at time of purchase are included with the purchase of this document.
