Specifies two methods for the potentiometric determination of the carbonyl value of essential oils which contain carbonyl compounds, either aldehydes or ketones. Method I is based on a cold oximation reaction with hydroxylammonium chloride. It applies to essential oils whose main constituents are easily oximable aldehydes and ketones, with the exception of citronellal which needs a low temperature to avoid cyclication phenomena and acetalization. Method II is based on a hot oximation reaction with hydroxylammonium chloride. It applies to essential oils whose main constituents are ketones which are in general oximable only with difficulty.
