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. |
