Название (англ.):
Essential oils; Determination of carbonyl value; Hydroxylammonium chloride method
Описание (англ.):
The determination is carried out by converting the carbonyl compounds to oximes by reaction with hydroxylammonium chloride. The hydrochloric acid liberated during the reaction is titrated with an ethanolic potassium hydroxide solution, either colorimetrically or potentiometrically. The method is applicable to essential oils the carbonyl compounds of which are aldehydes, methylketones or certain ketones which are easy to convert to oximes.
