Naphthenic acid by a general formula CH O, where "n" indicates the carbon number and "z" specifies a homologous series. The "z" is equal to 0 for saturated, acyclic acids and increases to 2 in monocyclic naphthenic acids, to 4 in bicyclic naphthenic acids, to 6 in tricyclic acids, and to 8 in tetracyclic acids. Salts of naphthenic acids, called naphthenates, are widely used as hydrophobic sources of metal ions in diverse applications.Aluminium salts of naphthenic acid and palmitic acid were combined during World War II to produce napalm. The word "napalm" is derived from the words naphthenic acid and palmitic acid.
Ucuhuba seed oil Ucuhuba seed oil Ucuhuba seed oil is the oil extracted from the seed of "Virola surinamensis" (ucuhuba). The ucuhuba tree is found in Brazil, Costa Rica, Ecuador, French Guiana, Guyana, Panama, Peru, Suriname, and Venezuela. Its seeds provide oil rich in myristic acid. The ucuhuba oil contains 13% lauric acid, 69% myristic acid, 7% palmitic acid and traces of oleic acid and linoleic acid. Myristic and lauric acids comprised 91.3 mole % of the total fatty acids. Although additional saturated fatty acids were found (decanoic acid, palmitic acid, and stearic acid), they occurred only as minor components. Small amounts of
