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.
Macleaya cordata dihydrochelerythrine, and twelve fatty acids of which linoleic, oleic, palmitic and stearic acids predominate. Macleaya cordata Macleaya cordata, the five-seeded plume-poppy, is a species of flowering plant in the poppy family Papaveraceae, which is used ornamentally. It is native to China and Japan. It is a large herbaceous perennial growing to tall by or more wide, with olive green leaves and airy panicles of buff-white flowers in summer. The Latin "cordata" means "heart-shaped", referring to the leaves. The common name plume poppy is used for plants of the genus "Macleaya".
