Essential oils. Determination of carbonyl value. Free hydroxylamine method Ingestion-build-117251 a) manual metal-arc welding1 Scope and field of application This International Standard specifies a method for the determination of the carbonyl value of essential oils. It is applicable to essential oils which contain carbonyl compounds (especially ketones, excluding methylketones) which are difficult to convert to oximes by the method specified in ISO 1279. The method is not applicable to essential oils which contain substantial amounts of esters or other alkali sensitive
