To this day, petroleum acids are still being studied by a number of researchers. Interest in the above class of organic compounds is not only attributed to practical perspective, but also to general humanitarian purposes. According to S. Nametkin, "... composition and structure of petroleum acids are closely related not only to the genesis of oil, but to the origin of life on Earth as well".
Depending on their origin, oils may contain different amounts of naphthenic acids, extremely insignificant in all cases. Naphthenic acids are extracted from oils using alkali alcoholic solutions. Structure of naphthenic acids in any oil is the same and depends on the nature of oil.
Among the oil produced worldwide, and particularly in the CIS region, Azerbaijan's oil features the highest content of petroleum acids. Oils of Bibi-Heybat, Romani, Binagadi, Balakhani, Sabunchi and other fields are rich in petroleum acids, which content in some crude oil grades reaches 1.5 – 2%. Due to the fact that acids extracted from naphthene-base crude of Baku oil fields have the same composition and physical-chemical properties as synthetic naphthenic acids, they are often referred to as natural naphthenic acids.

Naphthenic acids and their derivatives are widely used in more than 40 sectors of national economy.
Naphthenic acids in a form of lead, manganese, zinc, ferrum, aluminium, chrome salts and in a form of other derivatives, are used in preparation of paint driers, varnishes, paints.
Free naphthenic acids are used as a part of inks and improves their mobility. These acids are also used as thinner for aniline colorants, sleeper impregnation material preserving wood from rotting.
Both free and derivative naphthenic acids have effective fungicidal, insecticidal, bactericidal and preservative parameters which are used in weed and pest control, for impregnation of wood, sail fabric, canvas, rope, tarpaulin, fishing gear and other materials regularly affected by moisture, bacteria, pest, etc. Lead, chrome, cobalt and manganese salts of naphthenic acids are used as antistatic, antideteriorant and antifoam additives for fuel, jet engine fuels and oils. Lubricating and emulsifying materials used for cooling of shearing machines, pasting, lubrication grease for high-pressure plants, demulsifiers brea-king petroleum and oily emulsions are based on naphthenic acids.
Simple and compound ethers of naphthenic acids are used as plasticizers for production of polymeric materials, general rubber goods, polyvinylchloride plastic, hydraulic liquids, etc.
Naphthenic acids are successfully used even at cleaning of rareearth elements, extragens of radioactive materials, catalysts, oxidation and oxonation processes, agricultural growthregulating substances, drying accelerators for glassreinforced polyesters, etc.
In order to meet consumer needs for naphthenic acids, “KARVAN-L” company has developed technology and established commercial installations for output of high-purity acids.
