Naphthenic Acid/CAS: 1338-24-5
Description:
NAPHTHENIC ACID is a dark colored liquid with an offensive odor. NAPHTHENIC ACID is insoluble in water. NAPHTHENIC ACID will burn though NAPHTHENIC ACID may take some effort to ignite. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since NAPHTHENIC ACID is a liquid NAPHTHENIC ACID can easily penetrate the soil and contaminate groundwater and nearby streams. NAPHTHENIC ACID is used to make paint dryers, detergents, and solvents.

Usage
The term naphthenic acid, as commonly used in the petroleum industry, refers collectively to all of the carboxylic acids present in crude oil.
Naphthenic acid is commonly used in the synthesis of useful metal naphthenates such as copper naphthenate, a wood preservative; titanium naphthenate, a precursor for the preparation of titanium oxide thin films and a rare earth naphthenate, a lubricant oil additive. It can also be in the synthesis of biodegradable naphthenic acid ionic liquids.
