scope:
This International Standard specifies a method for the determination of ester value after acetylation. Through the determination of ester value before and after acetylation, it is possible to evaluate free alcohols and total alcohols content. This method is not applicable to essential oils containing appreciable quantities of tertiary alcohols which would not be completely acetylated, or phenols, lactones, aldehydes or enolysable ketones, which would be acetylated in addition to free alcohols.
