Palmitic acid World War II to produce napalm. The word "napalm" is derived from the words naphthenic acid and palmitic acid. Palmitic acid was discovered by Edmond Frémy in 1840, in saponified palm oil. This remains the primary industrial route for its production, with the triglycerides (fats) in palm oil being hydrolysed by high temperature water (above ), and the resulting mixture fractionally distilled to give the pure product. Palmitic acid is naturally produced by a wide range of other plants and organisms, typically at low levels. It is naturally present in butter, cheese, milk, and meat, as well as cocoa butter,
