Essential oils. Determination of carbonyl value. Potentiometric methods using hydroxylammonium chloride Ingestion-build-258901 for example EN 73 or1 SCOPE This International Standard specifies two methods for the potentiometric determination of the carbonyl value of essential oils which contain carbonyl compounds, either aldehydes or ketones. Method I (see clause 5), 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
