Metal Naphthenates Used for a Variety of Applications
Naturally Occurring Combination of Naphthenic Acids and Metal Ions
Example of cyclopentyl and cyclohexyl mixture comprising
Metal Naphthenate (n = 0-5 variable number of carbons).
(For different metals available see table)
Naphthenic acids are mixtures of cycloaliphatic carboxylic acid moities (primarily cyclopentyl and cyclohexyl) with varying structures (10 to 16 carbons long) isolated from crude oil. Metal naphthenates are salts of these naphthenic acids1 having the formula M(Naphthenate)2.2 They can be found naturally from the combination of naphthenic acids in crude oil with metal ions contained in water.
These naphthenate salts are soluble in certain organic carrier liquids and are an effective source of metal ions in organic media. Traditional applications2 include use in paint drying, wood treatment, anti-fouling agents, detergents, insecticides, fungicides, wetting agents, lubricants, surfactants, and corrosion inhibitors.
Listed below are various metal naphthenates that Strem has available for purchase.
