Naphthenic Acid

Naphthenic acids are technical mixtures of cyclopentane and cyclohexane acids, obtained through alkali extraction of special crude oil fractions. The composition of naphthenic acids fluctuates depending on the base crude oil that is used. The salts of naphthenic acids dissolve in the water fraction of the crude oil, and the naphthenic acids are recovered through acidification of the aqueous phase.
