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.

Naphthenic acids (NA) are used in a variety of commercial and industrial applications, and are primary toxic components of oil sands wastewater. We investigated developmental and metabolic responses of tadpoles exposed to sub-lethal concentrations of a commercial NA blend throughout

The toxicity of oil sands process-affected waters (OSPW) from the Athabasca Oil Sands (AOS) in northern Alberta, Canada, is related to a relatively persistent group of dissolved organic acids known as naphthenic acids (NAs). Naphthenic acids are a complex mixture
