Application
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.

The Canadian oil sands industry stores toxic oil sands process-affected water (OSPW) in large tailings ponds adjacent to the Athabasca River or its tributaries, raising concerns over potential seepage. Naphthenic acids (NAs; C(n)H(2n-Z)O(2)) are toxic components of OSPW, but are

Naphthenic acids (NAs) are an important group of trace organic pollutants predominantly comprising saturated aliphatic and alicyclic carboxylic acids. NAs are ubiquitous; occurring naturally in hydrocarbon deposits (petroleum, oil sands, bitumen, and crude oils) and also have widespread industrial uses.
