NAPHTHENIC ACID Chemical compatibility with O-rings, rubbers, & plastics

Naphthenic acid is a complex mixture of cyclopentyl and cyclohexyl carboxylic acids, commonly found in crude oil. It is used in various industrial applications, including the production of metal naphthenates, corrosion inhibitors, and wood preservatives. Naphthenic acid is also employed in the formulation of lubricants and fuel additives. Proper handling and storage of naphthenic acid are essential to prevent exposure and contamination. Safety measures should include the use of personal protective equipment, proper ventilation, and adherence to manufacturer guidelines. Regular monitoring and maintenance of processes using naphthenic acid ensure optimal performance and safety, making it a valuable component in the chemical, petroleum, and wood preservation industries.
