Crude Naphthenic Acid

MCRS can provide crude naphthenic acid products ranging in acid number from 160 to 230. Through a patented process, very high purity acids and specialty blends are also available with acid numbers ranging from 220 to 310.

MCRS crude naphthenic acid products are typically used as corrosion inhibitors and wood preservatives.

Crude naphthenic acids vary in unsaponifiable (non-carboxylic acid) matter from 7 percent to 30 percent by weight, but typically fall in the 10-20 percent range. Our high-purity naphthenic acids have a maximum of 3 percent unsaponifiables by weight.

Crude naphthenic acids are used in applications that have no color requirements. MCRS also makes refined naphthenic acids with color levels as low as 3 on the Gardner Scale.
