Essential oils. Determination of ester values, before and after acetylation, and evaluation of the contents of free and total alcohols not-eligible BS 9991 complements BS 99991 SCOPE This International Standard specifies a method to evaluate the contents of free alcohols and total alcohols in essential oils by determination of ester values before and after acetylation by acetic anhydride in the presence of sodium acetate. The method is not applicable to essential oils containing appreciable quantities of tertiary alcohols (for example linalol and terpineols), which would not be completely acetylated. NOTE: For these
