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. It's industrial applications include the production of metallic naphthenates, synthetic detergents and as a solvents. as a lubricant, Corrosion inhibitor and fuel additive.
