标准摘要
[中文适用范围]： 该评估是通过在二甲基苯胺存在下用乙酰氯和乙酸酐对精油进行乙酰化来进行的。 分离并干燥乙酰化油并测定酯值。 游离醇含量的计算考虑了相同但非乙酰化精油的酯值。 该方法适用于含有相当比例叔醇（即芳樟醇和萜品醇）的精油。 它不适用于含有大量酚类、邻氨基苯甲酸盐、内酯类和醛类的精油。 [外文原描述]： The estimation is carried out by acetylation of the essential oil by acetyl chloride and acetic anhydride, in the presence of dimethylaniline. The acetylated oil is isolated and dried and the ester value is determined. The free alcohols content is calculated taking into account the ester values of the same but non-acetylated essential oil. This method is applicable to essential oils containing an appreciable proportion of tertiary alcohols, namely of linalol and terpineol. It is not applicable to essential oils containing appreciable proportions of phenols, anthranilates, lactones and aldehydes.
英文名称Essential oils (containing tertiary alcohols) — Estimation of free alcohols content by determination of ester value after acetylation
