APPLICATIONS

Naphthenic acid is a complex of carboxylic acids( various low-molecular-weight fatty acids, believed to have cyclopentane ring mainly.) obtained as a by-product of petroleum refining; with  a variable composition and ingredients; generally 180 - 350 mole wt. It is used in deicing, dust control, wood preservative and road stabilization. Naphthenic acid and metallic naphthenates have industrial applications in synthetic detergents, solvent additives for paint, varnish, oils and resins. They are used as lubricants, corrosion inhibitors and fuel additives. They are used as wood preservatives; catalysts; insecticides; wetting agents; lubricating oil additive.

Paint driers are substances put into paint to make dry quickly. They are metallic salts of low-molecular-weight (chiefly C8) fatty acids or naphthenic acids. Naphthenic acid is a complex of carboxylic acids( various low-molecular-weight fatty acids believed to have cyclopentane ring mainly). Hydrocarbon parts take oxygen in air and metals act as catalyst to speed up the oxidative coating. Cobalt is the most useful. It is a powerful oxidation catalyst and can keep whiteness. Auxiliary metals should be added to prevent surface wrinkling after drying. Primary metals which can replace for cobalt are zirconium, lead, cerium and iron and auxiliary metals are like calcium, manganese, barium, zinc, lithium.
