Cobalt naphthenate Specification

Cobalt naphthenate (61789-51-3) is one of Naphthenic acids . Ir can be obtained as a by-product of petroleum refining. They are metallic salts of low-molecular-weight (chiefly C8) fatty acids or naphthenic acids. Cobalt is the most useful. It is a powerful oxidation catalyst and can keep whiteness. Often in technical literature, naphthenates are described as salts.
